+Abilis Systems TB10x pin controller
+===================================
+
+Required properties
+-------------------
+
+- compatible: should be "abilis,tb10x-iomux";
+- reg: should contain the physical address and size of the pin controller's
+ register range.
+
+
+Function definitions
+--------------------
+
+Functions are defined (and referenced) by sub-nodes of the pin controller.
+Every sub-node defines exactly one function (implying a set of pins).
+Every function is associated to one named pin group inside the pin controller
+driver and these names are used to associate pin group predefinitions to pin
+controller sub-nodes.
+
+Required function definition subnode properties:
+ - abilis,function: should be set to the name of the function's pin group.
+
+The following pin groups are available:
+ - GPIO ports: gpioa, gpiob, gpioc, gpiod, gpioe, gpiof, gpiog,
+ gpioh, gpioi, gpioj, gpiok, gpiol, gpiom, gpion
+ - Serial TS input ports: mis0, mis1, mis2, mis3, mis4, mis5, mis6, mis7
+ - Parallel TS input ports: mip1, mip3, mip5, mip7
+ - Serial TS output ports: mos0, mos1, mos2, mos3
+ - Parallel TS output port: mop
+ - CI+ port: ciplus
+ - CableCard (Mcard) port: mcard
+ - Smart card ports: stc0, stc1
+ - UART ports: uart0, uart1
+ - SPI ports: spi1, spi3
+ - JTAG: jtag
+
+All other ports of the chip are not multiplexed and thus not managed by this
+driver.
+
+
+GPIO ranges definition
+----------------------
+
+The named pin groups of GPIO ports can be used to define GPIO ranges as
+explained in Documentation/devicetree/bindings/gpio/gpio.txt.
+
+
+Example
+-------
+
+iomux: iomux@ff10601c {
+ compatible = "abilis,tb10x-iomux";
+ reg = <0xFF10601c 0x4>;

+ };
+ pctl_uart0: pctl-uart0 {
+ abilis,function = "uart0";
+ };
+};
+uart@ff100000 {

+ reg = <0xFF100000 0x100>;
+ clock-frequency = <166666666>;
+ interrupts = <25 1>;
+ reg-shift = <2>;
+ reg-io-width = <4>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pctl_uart0>;

+Actions Semi S700 Pin Controller
+
+This binding describes the pin controller found in the S700 SoC.
+
+Required Properties:
+
+- compatible: Should be "actions,s700-pinctrl"
+- reg: Should contain the register base address and size of
+ the pin controller.
+- clocks: phandle of the clock feeding the pin controller
+- gpio-controller: Marks the device node as a GPIO controller.
+- gpio-ranges: Specifies the mapping between gpio controller and
+ pin-controller pins.
+- #gpio-cells: Should be two. The first cell is the gpio pin number
+ and the second cell is used for optional parameters.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt. Shall be set to 2. The first cell
+ defines the interrupt number, the second encodes
+ the trigger flags described in
+ bindings/interrupt-controller/interrupts.txt
+- interrupts: The interrupt outputs from the controller. There is one GPIO
+ interrupt per GPIO bank. The number of interrupts listed depends
+ on the number of GPIO banks on the SoC. The interrupts must be
+ ordered by bank, starting with bank 0.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+Pinmux functions are available only for the pin groups while pinconf
+parameters are available for both pin groups and individual pins.
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+Required Properties:
+

+Actions Semi S900 Pin Controller
+
+This binding describes the pin controller found in the S900 SoC.
+
+Required Properties:
+
+- compatible: Should be "actions,s900-pinctrl"
+- reg: Should contain the register base address and size of
+ the pin controller.
+- clocks: phandle of the clock feeding the pin controller
+- gpio-controller: Marks the device node as a GPIO controller.
+- gpio-ranges: Specifies the mapping between gpio controller and
+ pin-controller pins.
+- #gpio-cells: Should be two. The first cell is the gpio pin number
+ and the second cell is used for optional parameters.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Specifies the number of cells needed to encode an
+ interrupt. Shall be set to 2. The first cell
+ defines the interrupt number, the second encodes
+ the trigger flags described in
+ bindings/interrupt-controller/interrupts.txt
+- interrupts: The interrupt outputs from the controller. There is one GPIO
+ interrupt per GPIO bank. The number of interrupts listed depends
+ on the number of GPIO banks on the SoC. The interrupts must be
+ ordered by bank, starting with bank 0.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+PIN CONFIGURATION NODES:
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+Pinmux functions are available only for the pin groups while pinconf
+parameters are available for both pin groups and individual pins.
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+Required Properties:

+* Atmel AT91 Pinmux Controller
+
+The AT91 Pinmux Controller, enables the IC
+to share one PAD to several functional blocks. The sharing is done by
+multiplexing the PAD input/output signals. For each PAD there are up to
+8 muxing options (called periph modes). Since different modules require
+different PAD settings (like pull up, keeper, etc) the controller controls
+also the PAD settings parameters.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Atmel AT91 pin configuration node is a node of a group of pins which can be
+used for a specific device or function. This node represents both mux and config
+of the pins in that group. The 'pins' selects the function mode(also named pin
+mode) this pin can work on and the 'config' configures various pad settings
+such as pull-up, multi drive, etc.
+
+Required properties for iomux controller:
+- compatible: "atmel,at91rm9200-pinctrl" or "atmel,at91sam9x5-pinctrl"
+ or "atmel,sama5d3-pinctrl" or "microchip,sam9x60-pinctrl"
+- atmel,mux-mask: array of mask (periph per bank) to describe if a pin can be
+ configured in this periph mode. All the periph and bank need to be describe.
+
+How to create such array:
+
+Each column will represent the possible peripheral of the pinctrl
+Each line will represent a pio bank
+
+Take an example on the 9260
+Peripheral: 2 ( A and B)
+Bank: 3 (A, B and C)

+
+ /* A B */
+ 0xffffffff 0xffc00c3b /* pioA */
+ 0xffffffff 0x7fff3ccf /* pioB */
+ 0xffffffff 0x007fffff /* pioC */
+
+For each peripheral/bank we will describe in a u32 if a pin can be
+configured in it by putting 1 to the pin bit (1 << pin)
+
+Let's take the pioA on peripheral B
+From the datasheet Table 10-2.

+
+Required properties for pin configuration node:
+- atmel,pins: 4 integers array, represents a group of pins mux and config
+ setting. The format is atmel,pins = <PIN_BANK PIN_BANK_NUM PERIPH CONFIG>.
+ The PERIPH 0 means gpio, PERIPH 1 is periph A, PERIPH 2 is periph B...
+ PIN_BANK 0 is pioA, PIN_BANK 1 is pioB...
+
+Bits used for CONFIG:
+PULL_UP (1 << 0): indicate this pin needs a pull up.
+MULTIDRIVE (1 << 1): indicate this pin needs to be configured as multi-drive.
+ Multi-drive is equivalent to open-drain type output.
+DEGLITCH (1 << 2): indicate this pin needs deglitch.
+PULL_DOWN (1 << 3): indicate this pin needs a pull down.
+DIS_SCHMIT (1 << 4): indicate this pin needs to the disable schmitt trigger.
+DRIVE_STRENGTH (3 << 5): indicate the drive strength of the pin using the
+ following values:
+ 00 - No change (reset state value kept)
+ 01 - Low
+ 10 - Medium
+ 11 - High
+OUTPUT (1 << 7): indicate this pin need to be configured as an output.
+OUTPUT_VAL (1 << 8): output val (1 = high, 0 = low)
+SLEWRATE (1 << 9): slew rate of the pin: 0 = disable, 1 = enable
+DEBOUNCE (1 << 16): indicate this pin needs debounce.
+DEBOUNCE_VAL (0x3fff << 17): debounce value.
+
+NOTE:
+Some requirements for using atmel,at91rm9200-pinctrl binding:
+1. We have pin function node defined under at91 controller node to represent
+ what pinmux functions this SoC supports.
+2. The driver can use the function node's name and pin configuration node's
+ name describe the pin function and group hierarchy.
+ For example, Linux at91 pinctrl driver takes the function node's name
+ as the function name and pin configuration node's name as group name to
+ create the map table.
+3. Each pin configuration node should have a phandle, devices can set pins
+ configurations by referring to the phandle of that pin configuration node.
+4. The gpio controller must be describe in the pinctrl simple-bus.
+
+For each bank the required properties are:
+- compatible: "atmel,at91sam9x5-gpio" or "atmel,at91rm9200-gpio" or
+ "microchip,sam9x60-gpio"
+- reg: physical base address and length of the controller's registers
+- interrupts: interrupt outputs from the controller
+- interrupt-controller: marks the device node as an interrupt controller
+- #interrupt-cells: should be 2; refer to ../interrupt-controller/interrupts.txt

+* Pin-controller driver for the Marvell Berlin SoCs
+
+Pin control registers are part of both chip controller and system
+controller register sets. Pin controller nodes should be a sub-node of
+either the chip controller or system controller node. The pins
+controlled are organized in groups, so no actual pin information is
+needed.
+
+A pin-controller node should contain subnodes representing the pin group
+configurations, one per function. Each subnode has the group name and
+the muxing function used.

+Bitmain BM1880 Pin Controller
+
+This binding describes the pin controller found in the BM1880 SoC.
+
+Required Properties:
+
+- compatible: Should be "bitmain,bm1880-pinctrl"
+- reg: Offset and length of pinctrl space in SCTRL.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+The pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration for BM1880 SoC
+includes pinmux and various pin configuration parameters, such as pull-up,
+slew rate etc...
+
+Each configuration node can consist of multiple nodes describing the pinmux
+options. The name of each subnode is not important; all subnodes should be
+enumerated and processed purely based on their content.
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pinmux subnode:
+
+Required Properties:
+
+- pins: An array of strings, each string containing the name of a pin.
+ Valid values for pins are:
+
+ MIO0 - MIO111
+
+- groups: An array of strings, each string containing the name of a pin
+ group. Valid values for groups are:
+
+ nand_grp, spi_grp, emmc_grp, sdio_grp, eth0_grp, pwm0_grp,

+Broadcom BCM2835 GPIO (and pinmux) controller
+
+The BCM2835 GPIO module is a combined GPIO controller, (GPIO) interrupt
+controller, and pinmux/control device.
+
+Required properties:
+- compatible: "brcm,bcm2835-gpio"
+- compatible: should be one of:
+ "brcm,bcm2835-gpio" - BCM2835 compatible pinctrl
+ "brcm,bcm7211-gpio" - BCM7211 compatible pinctrl
+ "brcm,bcm2711-gpio" - BCM2711 compatible pinctrl
+ "brcm,bcm7211-gpio" - BCM7211 compatible pinctrl
+- reg: Should contain the physical address of the GPIO module's registers.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two. The first cell is the pin number and the
+ second cell is used to specify optional parameters:
+ - bit 0 specifies polarity (0 for normal, 1 for inverted)
+- interrupts : The interrupt outputs from the controller. One interrupt per
+ individual bank followed by the "all banks" interrupt. For BCM7211, an
+ additional set of per-bank interrupt line and an "all banks" wake-up
+ interrupt may be specified.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells : Should be 2.
+ The first cell is the GPIO number.
+ The second cell is used to specify flags:
+ bits[3:0] trigger type and level flags:
+ 1 = low-to-high edge triggered.
+ 2 = high-to-low edge triggered.
+ 4 = active high level-sensitive.
+ 8 = active low level-sensitive.
+ Valid combinations are 1, 2, 3, 4, 8.
+
+Please refer to ../gpio/gpio.txt for a general description of GPIO bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Each pin configuration node lists the pin(s) to which it applies, and one or
+more of the mux function to select on those pin(s), and pull-up/down
+configuration. Each subnode only affects those parameters that are explicitly
+listed. In other words, a subnode that lists only a mux function implies no
+information about any pull configuration. Similarly, a subnode that lists only
+a pul parameter implies no information about the mux function.
+
+The BCM2835 pin configuration and multiplexing supports the generic bindings.
+For details on each properties, you can refer to ./pinctrl-bindings.txt.
+
+Required sub-node properties:
+ - pins
+ - function
+
+Optional sub-node properties:
+ - bias-disable
+ - bias-pull-up
+ - bias-pull-down
+ - output-high
+ - output-low
+
+Legacy pin configuration and multiplexing binding:
+*** (Its use is deprecated, use generic multiplexing and configuration
+bindings instead)
+
+Required subnode-properties:
+- brcm,pins: An array of cells. Each cell contains the ID of a pin. Valid IDs
+ are the integer GPIO IDs; 0==GPIO0, 1==GPIO1, ... 53==GPIO53.
+
+Optional subnode-properties:
+- brcm,function: Integer, containing the function to mux to the pin(s):
+ 0: GPIO in
+ 1: GPIO out
+ 2: alt5
+ 3: alt4
+ 4: alt0
+ 5: alt1
+ 6: alt2
+ 7: alt3
+- brcm,pull: Integer, representing the pull-down/up to apply to the pin(s):
+ 0: none
+ 1: down
+ 2: up
+
+Each of brcm,function and brcm,pull may contain either a single value which
+will be applied to all pins in brcm,pins, or 1 value for each entry in
+brcm,pins.
+
+Example:
+
+ gpio: gpio {
+ compatible = "brcm,bcm2835-gpio";
+ reg = <0x2200000 0xb4>;
+ interrupts = <2 17>, <2 19>, <2 18>, <2 20>;
+
+ gpio-controller;
+ #gpio-cells = <2>;
+
+ interrupt-controller;
+ #interrupt-cells = <2>;
+ };

+Broadcom iProc GPIO/PINCONF Controller
+
+Required properties:
+
+- compatible:
+ "brcm,iproc-gpio" for the generic iProc based GPIO controller IP that
+ supports full-featured pinctrl and GPIO functions used in various iProc
+ based SoCs
+
+ May contain an SoC-specific compatibility string to accommodate any
+ SoC-specific features
+
+ "brcm,cygnus-ccm-gpio", "brcm,cygnus-asiu-gpio", or
+ "brcm,cygnus-crmu-gpio" for Cygnus SoCs
+
+ "brcm,iproc-nsp-gpio" for the iProc NSP SoC that has drive strength support
+ disabled
+
+ "brcm,iproc-stingray-gpio" for the iProc Stingray SoC that has the general
+ pinctrl support completely disabled in this IP block. In Stingray, a
+ different IP block is used to handle pinctrl related functions
+
+- reg:
+ Define the base and range of the I/O address space that contains SoC
+GPIO/PINCONF controller registers
+
+- ngpios:
+ Total number of in-use slots in GPIO controller
+
+- #gpio-cells:
+ Must be two. The first cell is the GPIO pin number (within the
+controller's pin space) and the second cell is used for the following:
+ bit[0]: polarity (0 for active high and 1 for active low)
+
+- gpio-controller:
+ Specifies that the node is a GPIO controller
+
+Optional properties:
+
+- interrupts:
+ Interrupt ID
+
+- interrupt-controller:
+ Specifies that the node is an interrupt controller
+
+- gpio-ranges:
+ Specifies the mapping between gpio controller and pin-controllers pins.
+ This requires 4 fields in cells defined as -
+ 1. Phandle of pin-controller.
+ 2. GPIO base pin offset.
+ 3 Pin-control base pin offset.
+ 4. number of gpio pins which are linearly mapped from pin base.
+
+Supported generic PINCONF properties in child nodes:
+
+- pins:
+ The list of pins (within the controller's own pin space) that properties
+in the node apply to. Pin names are "gpio-<pin>"
+
+- bias-disable:
+ Disable pin bias
+
+- bias-pull-up:
+ Enable internal pull up resistor
+
+- bias-pull-down:
+ Enable internal pull down resistor
+
+- drive-strength:
+ Valid drive strength values include 2, 4, 6, 8, 10, 12, 14, 16 (mA)
+
+Example:
+ gpio_ccm: gpio@1800a000 {

+Conexant Digicolor CX92755 General Purpose Pin Mapping
+
+This document describes the device tree binding of the pin mapping hardware
+modules in the Conexant Digicolor CX92755 SoCs. The CX92755 in one of the
+Digicolor series of SoCs.
+
+=== Pin Controller Node ===
+
+Required Properties:
+
+- compatible: Must be "cnxt,cx92755-pinctrl"
+- reg: Base address of the General Purpose Pin Mapping register block and the
+ size of the block.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells: Must be <2>. The first cell is the pin number and the
+ second cell is used to specify flags. See include/dt-bindings/gpio/gpio.h
+ for possible values.
+
+For example, the following is the bare minimum node:
+
+ pinctrl: pinctrl@f0000e20 {
+ compatible = "cnxt,cx92755-pinctrl";
+ reg = <0xf0000e20 0x100>;
+ gpio-controller;
+ #gpio-cells = <2>;
+ };
+
+As a pin controller device, in addition to the required properties, this node
+should also contain the pin configuration nodes that client devices reference,
+if any.
+
+For a general description of GPIO bindings, please refer to ../gpio/gpio.txt.
+
+=== Pin Configuration Node ===
+
+Each pin configuration node is a sub-node of the pin controller node and is a
+container of an arbitrary number of subnodes, called pin group nodes in this
+document.
+
+Please refer to the pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the definition of a
+"pin configuration node".
+
+=== Pin Group Node ===
+
+A pin group node specifies the desired pin mux for an arbitrary number of
+pins. The name of the pin group node is optional and not used.
+
+A pin group node only affects the properties specified in the node, and has no
+effect on any properties that are omitted.
+
+The pin group node accepts a subset of the generic pin config properties. For
+details generic pin config properties, please refer to pinctrl-bindings.txt
+and <include/linux/pinctrl/pinconfig-generic.h>.
+
+Required Pin Group Node Properties:
+
+- pins: Multiple strings. Specifies the name(s) of one or more pins to be
+ configured by this node. The format of a pin name string is "GP_xy", where x
+ is an uppercase character from 'A' to 'R', and y is a digit from 0 to 7.
+- function: String. Specifies the pin mux selection. Values must be one of:
+ "gpio", "client_a", "client_b", "client_c"
+
+Example:
+ pinctrl: pinctrl@f0000e20 {
+ compatible = "cnxt,cx92755-pinctrl";
+ reg = <0xf0000e20 0x100>;
+
+ uart0_default: uart0_active {
+ data_signals {
+ pins = "GP_O0", "GP_O1";
+ function = "client_b";
+ };
+ };
+ };
+
+ uart0: uart@f0000740 {
+ compatible = "cnxt,cx92755-usart";
+ ...
+ pinctrl-0 = <&uart0_default>;
+ pinctrl-names = "default";
+ };
+
+In the example above, a single pin group configuration node defines the
+"client select" for the Rx and Tx signals of uart0. The uart0 node references
+that pin configuration node using the &uart0_default phandle.

+Cortina Systems Gemini pin controller
+
+This pin controller is found in the Cortina Systems Gemini SoC family,
+see further arm/gemini.txt. It is a purely group-based multiplexing pin

+* Freescale IOMUX Controller (IOMUXC) for i.MX
+
+The IOMUX Controller (IOMUXC), together with the IOMUX, enables the IC
+to share one PAD to several functional blocks. The sharing is done by
+multiplexing the PAD input/output signals. For each PAD there are up to
+8 muxing options (called ALT modes). Since different modules require
+different PAD settings (like pull up, keeper, etc) the IOMUXC controls
+also the PAD settings parameters.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Freescale IMX pin configuration node is a node of a group of pins which can be
+used for a specific device or function. This node represents both mux and config
+of the pins in that group. The 'mux' selects the function mode(also named mux
+mode) this pin can work on and the 'config' configures various pad settings
+such as pull-up, open drain, drive strength, etc.
+
+Required properties for iomux controller:
+- compatible: "fsl,<soc>-iomuxc"
+ Please refer to each fsl,<soc>-pinctrl.txt binding doc for supported SoCs.
+
+Required properties for pin configuration node:
+- fsl,pins: each entry consists of 6 integers and represents the mux and config
+ setting for one pin. The first 5 integers <mux_reg conf_reg input_reg mux_val
+ input_val> are specified using a PIN_FUNC_ID macro, which can be found in
+ imx*-pinfunc.h under device tree source folder. The last integer CONFIG is
+ the pad setting value like pull-up on this pin. And that's why fsl,pins entry
+ looks like <PIN_FUNC_ID CONFIG> in the example below.
+
+Bits used for CONFIG:
+NO_PAD_CTL(1 << 31): indicate this pin does not need config.
+
+SION(1 << 30): Software Input On Field.
+Force the selected mux mode input path no matter of MUX_MODE functionality.
+By default the input path is determined by functionality of the selected
+mux mode (regular).
+
+Other bits are used for PAD setting.
+Please refer to each fsl,<soc>-pinctrl,txt binding doc for SoC specific part
+of bits definitions.
+
+NOTE:
+Some requirements for using fsl,imx-pinctrl binding:
+1. We have pin function node defined under iomux controller node to represent
+ what pinmux functions this SoC supports.
+2. The pin configuration node intends to work on a specific function should
+ to be defined under that specific function node.
+ The function node's name should represent well about what function
+ this group of pins in this pin configuration node are working on.
+3. The driver can use the function node's name and pin configuration node's
+ name describe the pin function and group hierarchy.
+ For example, Linux IMX pinctrl driver takes the function node's name
+ as the function name and pin configuration node's name as group name to
+ create the map table.
+4. Each pin configuration node should have a phandle, devices can set pins
+ configurations by referring to the phandle of that pin configuration node.
+
+Examples:
+usdhc@219c000 { /* uSDHC4 */
+ non-removable;
+ vmmc-supply = <®_3p3v>;
+ pinctrl-names = "default";
+ pinctrl-0 = <&pinctrl_usdhc4_1>;
+};
+
+iomuxc@20e0000 {
+ compatible = "fsl,imx6q-iomuxc";
+ reg = <0x020e0000 0x4000>;
+
+ /* shared pinctrl settings */
+ usdhc4 {
+ pinctrl_usdhc4_1: usdhc4grp-1 {
+ fsl,pins = <
+ MX6QDL_PAD_SD4_CMD__SD4_CMD 0x17059

+ MX6QDL_PAD_SD4_DAT7__SD4_DATA7 0x17059
+ >;
+ };
+ ....
+};
+Refer to the IOMUXC controller chapter in imx6q datasheet,
+0x17059 means enable hysteresis, 47KOhm Pull Up, 50Mhz speed,
+80Ohm driver strength and Fast Slew Rate.
+User should refer to each SoC spec to set the correct value.

+ B. GPIO function should be selected if this is configured.
+ Possible values:
+ 0 - GPIO_IN
+ 1 - Interrupt Status Register
+ 2 - Pulldown
+ 3 - Pullup
+ Registers ICONFA1, ICONFA2, ICONFB1 and ICONFB2
+
+ CONFIG can be 0 or 1, meaning Pullup disable/enable.
+
+
+The iomux controller has gpio child nodes which are embedded in the iomux
+control registers. They have to be defined as child nodes of the iomux device
+node. If gpio subnodes are defined "#address-cells", "#size-cells" and "ranges"
+properties for the iomux device node are required.
+
+Example:
+
+iomuxc: iomuxc@10015000 {
+ compatible = "fsl,imx27-iomuxc";
+ reg = <0x10015000 0x600>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ gpio1: gpio@10015000 {
+ ...
+ };
+
+ ...
+
+ uart {
+ pinctrl_uart1: uart-1 {
+ fsl,pins = <
+ 0x8c 0x004 0x0 /* UART1_TXD__UART1_TXD */
+ 0x8d 0x000 0x0 /* UART1_RXD__UART1_RXD */
+ 0x8e 0x004 0x0 /* UART1_CTS__UART1_CTS */
+ 0x8f 0x000 0x0 /* UART1_RTS__UART1_RTS */
+ >;
+ };
+
+ ...
+ };
+};
+
+
+For convenience there are macros defined in imx27-pinfunc.h which provide PIN
+and MUX_ID. They are structured as MX27_PAD_<Pad name>__<Signal name>. The names
+are defined in the i.MX27 reference manual.
+
+The above example using macros:
+
+iomuxc: iomuxc@10015000 {
+ compatible = "fsl,imx27-iomuxc";
+ reg = <0x10015000 0x600>;
+ #address-cells = <1>;
+ #size-cells = <1>;
+ ranges;
+
+ gpio1: gpio@10015000 {
+ ...
+ };
+
+ ...
+
+ uart {
+ pinctrl_uart1: uart-1 {
+ fsl,pins = <
+ MX27_PAD_UART1_TXD__UART1_TXD 0x0
+ MX27_PAD_UART1_RXD__UART1_RXD 0x0
+ MX27_PAD_UART1_CTS__UART1_CTS 0x0
+ MX27_PAD_UART1_RTS__UART1_RTS 0x0
+ >;

+* Freescale i.MX7ULP IOMUX Controller
+
+i.MX 7ULP has three IOMUXC instances: IOMUXC0 for M4 ports, IOMUXC1 for A7
+ports and IOMUXC DDR for DDR interface.
+
+Note:
+This binding doc is only for the IOMUXC1 support in A7 Domain and it only
+supports generic pin config.
+
+Please refer to fsl,imx-pinctrl.txt in this directory for common binding
+part and usage.
+
+Required properties:
+- compatible: "fsl,imx7ulp-iomuxc1".
+- fsl,pins: Each entry consists of 5 integers which represents the mux
+ and config setting for one pin. The first 4 integers
+ <mux_conf_reg input_reg mux_mode input_val> are specified
+ using a PIN_FUNC_ID macro, which can be found in
+ imx7ulp-pinfunc.h in the device tree source folder.
+ The last integer CONFIG is the pad setting value like
+ pull-up on this pin.
+
+ Please refer to i.MX7ULP Reference Manual for detailed
+ CONFIG settings.
+
+CONFIG bits definition:
+PAD_CTL_OBE (1 << 17)
+PAD_CTL_IBE (1 << 16)
+PAD_CTL_LK (1 << 16)

+* Freescale MXS Pin Controller
+
+The pins controlled by mxs pin controller are organized in banks, each bank
+has 32 pins. Each pin has 4 multiplexing functions, and generally, the 4th
+function is GPIO. The configuration on the pins includes drive strength,
+voltage and pull-up.
+
+Required properties:
+- compatible: "fsl,imx23-pinctrl" or "fsl,imx28-pinctrl"
+- reg: Should contain the register physical address and length for the
+ pin controller.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices.
+
+The node of mxs pin controller acts as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for
+a group of pins, and only affects those parameters that are explicitly listed.
+In other words, a subnode that describes a drive strength parameter implies no
+information about pull-up. For this reason, even seemingly boolean values are
+actually tristates in this binding: unspecified, off, or on. Unspecified is
+represented as an absent property, and off/on are represented as integer
+values 0 and 1.
+
+Those subnodes under mxs pin controller node will fall into two categories.
+One is to set up a group of pins for a function, both mux selection and pin
+configurations, and it's called group node in the binding document. The other
+one is to adjust the pin configuration for some particular pins that need a
+different configuration than what is defined in group node. The binding
+document calls this type of node config node.
+
+On mxs, there is no hardware pin group. The pin group in this binding only
+means a group of pins put together for particular peripheral to work in
+particular function, like SSP0 functioning as mmc0-8bit. That said, the
+group node should include all the pins needed for one function rather than
+having these pins defined in several group nodes. It also means each of
+"pinctrl-*" phandle in client device node should only have one group node
+pointed in there, while the phandle can have multiple config node referenced
+there to adjust configurations for some pins in the group.
+
+Required subnode-properties:
+- fsl,pinmux-ids: An integer array. Each integer in the array specify a pin
+ with given mux function, with bank, pin and mux packed as below.
+
+ [15..12] : bank number
+ [11..4] : pin number
+ [3..0] : mux selection
+
+ This integer with mux selection packed is used as an entity by both group
+ and config nodes to identify a pin. The mux selection in the integer takes
+ effects only on group node, and will get ignored by driver with config node,
+ since config node is only meant to set up pin configurations.
+
+ Valid values for these integers are listed below.
+
+- reg: Should be the index of the group nodes for same function. This property
+ is required only for group nodes, and should not be present in any config
+ nodes.
+
+Optional subnode-properties:
+- fsl,drive-strength: Integer.
+ 0: MXS_DRIVE_4mA
+ 1: MXS_DRIVE_8mA
+ 2: MXS_DRIVE_12mA
+ 3: MXS_DRIVE_16mA
+- fsl,voltage: Integer.
+ 0: MXS_VOLTAGE_LOW - 1.8 V
+ 1: MXS_VOLTAGE_HIGH - 3.3 V
+- fsl,pull-up: Integer.
+ 0: MXS_PULL_DISABLE - Disable the internal pull-up
+ 1: MXS_PULL_ENABLE - Enable the internal pull-up
+
+Note that when enabling the pull-up, the internal pad keeper gets disabled.
+Also, some pins doesn't have a pull up, in that case, setting the fsl,pull-up
+will only disable the internal pad keeper.
+

+ #size-cells = <0>;

+In this example, group node mmc0-8bit defines a group of pins for mxs SSP0
+to function as a 8-bit mmc device, with 8mA, 3.3V and pull-up configurations
+applied on all these pins. And config nodes mmc-cd-cfg and mmc-sck-cfg are
+adjusting the configuration for pins card-detection and clock from what group
+node mmc0-8bit defines. Only the configuration properties to be adjusted need
+to be listed in the config nodes.
+
+Valid values for i.MX28/i.MX23 pinmux-id are defined in
+arch/arm/boot/dts/imx28-pinfunc.h and arch/arm/boot/dts/imx23-pinfunc.h.
+The definitions for the padconfig properties can be found in
+arch/arm/boot/dts/mxs-pinfunc.h.

+Imagination Technologies Pistachio SoC pin controllers
+======================================================
+
+The pin controllers on Pistachio are a combined GPIO controller, (GPIO)
+interrupt controller, and pinmux + pinconf device. The system ("east") pin
+controller on Pistachio has 99 pins, 90 of which are MFIOs which can be
+configured as GPIOs. The 90 GPIOs are divided into 6 banks of up to 16 GPIOs
+each. The GPIO banks are represented as sub-nodes of the pad controller node.
+
+Please refer to pinctrl-bindings.txt, ../gpio/gpio.txt, and
+../interrupt-controller/interrupts.txt for generic information regarding
+pin controller, GPIO, and interrupt bindings.
+
+Required properties for pin controller node:
+--------------------------------------------
+ - compatible: "img,pistachio-system-pinctrl".
+ - reg: Address range of the pinctrl registers.
+
+Required properties for GPIO bank sub-nodes:
+--------------------------------------------
+ - interrupts: Interrupt line for the GPIO bank.
+ - gpio-controller: Indicates the device is a GPIO controller.

+description: >
+ Please refer to pinctrl-bindings.txt in this directory for details of the
+ common pinctrl bindings used by client devices, including the meaning of the
+ phrase "pin configuration node".
+
+ For the Ingenic SoCs, pin control is tightly bound with GPIO ports. All pins
+ may be used as GPIOs, multiplexed device functions are configured within the
+ GPIO port configuration registers and it is typical to refer to pins using the
+ naming scheme "PxN" where x is a character identifying the GPIO port with
+ which the pin is associated and N is an integer from 0 to 31 identifying the
+ pin within that GPIO port. For example PA0 is the first pin in GPIO port A,
+ and PB31 is the last pin in GPIO port B. The JZ4730, the JZ4740, the JZ4725B,
+ the X1000 and the X1830 contains 4 GPIO ports, PA to PD, for a total of 128
+ pins. The X2000 and the X2100 contains 5 GPIO ports, PA to PE, for a total of
+ 160 pins. The JZ4750, the JZ4755 the JZ4760, the JZ4770 and the JZ4780 contains
+ 6 GPIO ports, PA to PF, for a total of 192 pins. The JZ4775 contains 7 GPIO
+ ports, PA to PG, for a total of 224 pins.

+Lantiq FALCON pinmux controller

+Required properties:

+ register range
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Lantiq's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those group(s), and two pin configuration parameters:
+pull-up and open-drain
+
+The name of each subnode is not important as long as it is unique; all subnodes
+should be enumerated and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+We support 2 types of nodes.
+
+Definition of mux function groups:
+
+Required subnode-properties:
+- lantiq,groups : An array of strings. Each string contains the name of a group.
+ Valid values for these names are listed below.
+- lantiq,function: A string containing the name of the function to mux to the
+ group. Valid values for function names are listed below.
+
+Valid values for group and function names:
+

+* Marvell Armada 37xx SoC pin and gpio controller
+
+Each Armada 37xx SoC come with two pin and gpio controller one for the
+south bridge and the other for the north bridge.
+
+Inside this set of register the gpio latch allows exposing some
+configuration of the SoC and especially the clock frequency of the
+xtal. Hence, this node is a represent as syscon allowing sharing the
+register between multiple hardware block.

+* Marvell SoC pinctrl core driver for mpp
+
+The pinctrl driver enables Marvell SoCs to configure the multi-purpose pins
+(mpp) to a specific function. For each SoC family there is a SoC specific
+driver using this core driver.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+A Marvell SoC pin configuration node is a node of a group of pins which can
+be used for a specific device or function. Each node requires one or more
+mpp pins or group of pins and a mpp function common to all pins.
+
+Required properties for pinctrl driver:
+- compatible: "marvell,<soc>-pinctrl"
+ Please refer to each marvell,<soc>-pinctrl.txt binding doc for supported SoCs.
+
+Required properties for pin configuration node:
+- marvell,pins: string array of mpp pins or group of pins to be muxed.
+- marvell,function: string representing a function to mux to for all
+ marvell,pins given in this pin configuration node. The function has to be
+ common for all marvell,pins. Please refer to marvell,<soc>-pinctrl.txt for
+ valid pin/pin group names and available function names for each SoC.
+
+Examples:
+
+uart1: serial@12100 {
+ compatible = "ns16550a";
+ reg = <0x12100 0x100>;
+ reg-shift = <2>;
+ interrupts = <7>;
+
+ pinctrl-0 = <&pmx_uart1_sw>;
+ pinctrl-names = "default";
+};
+
+pinctrl: pinctrl@d0200 {
+ compatible = "marvell,dove-pinctrl";
+ reg = <0xd0200 0x14>, <0xd0440 0x04>, <0xd802c 0x08>;
+
+ pmx_uart1_sw: pmx-uart1-sw {
+ marvell,pins = "mpp_uart1";
+ marvell,function = "uart1";
+ };
+};

+ Describe the specific driving setup property.
+ For I2C pins, the existing generic driving setup can only support
+ 2/4/6/8/10/12/14/16mA driving. But in specific driving setup, they
+ can support 0.125/0.25/0.5/1mA adjustment. If we enable specific
+ driving setup, the existing generic setup will be disabled.
+ The specific driving setup is controlled by E1E0EN.
+ When E1=0/E0=0, the strength is 0.125mA.
+ When E1=0/E0=1, the strength is 0.25mA.
+ When E1=1/E0=0, the strength is 0.5mA.
+ When E1=1/E0=1, the strength is 1mA.
+ EN is used to enable or disable the specific driving setup.
+ Valid arguments are described as below:
+ 0: (E1, E0, EN) = (0, 0, 0)
+ 1: (E1, E0, EN) = (0, 0, 1)
+ 2: (E1, E0, EN) = (0, 1, 0)

+ 6: (E1, E0, EN) = (1, 1, 0)
+ 7: (E1, E0, EN) = (1, 1, 1)

+ The specific driving setup is controlled by E1E0EN.
+ When E1=0/E0=0, the strength is 0.125mA.
+ When E1=0/E0=1, the strength is 0.25mA.
+ When E1=1/E0=0, the strength is 0.5mA.
+ When E1=1/E0=1, the strength is 1mA.
+ EN is used to enable or disable the specific driving setup.
+ Valid arguments are described as below:
+ 0: (E1, E0, EN) = (0, 0, 0)

+* Microchip PIC32 Pin Controller
+
+Please refer to pinctrl-bindings.txt, ../gpio/gpio.txt, and
+../interrupt-controller/interrupts.txt for generic information regarding
+pin controller, GPIO, and interrupt bindings.
+
+PIC32 'pin configuration node' is a node of a group of pins which can be
+used for a specific device or function. This node represents configurations of
+pins, optional function, and optional mux related configuration.
+
+Required properties for pin controller node:
+ - compatible: "microchip,pic32mada-pinctrl"
+ - reg: Address range of the pinctrl registers.
+ - clocks: Clock specifier (see clock bindings for details)
+
+Required properties for pin configuration sub-nodes:
+ - pins: List of pins to which the configuration applies.
+
+Optional properties for pin configuration sub-nodes:
+----------------------------------------------------
+ - function: Mux function for the specified pins.
+ - bias-pull-up: Enable weak pull-up.
+ - bias-pull-down: Enable weak pull-down.
+ - input-enable: Set the pin as an input.
+ - output-low: Set the pin as an output level low.
+ - output-high: Set the pin as an output level high.

+Nuvoton NPCM7XX Pin Controllers
+
+The Nuvoton BMC NPCM7XX Pin Controller multi-function routed through
+the multiplexing block, Each pin supports GPIO functionality (GPIOx)
+and multiple functions that directly connect the pin to different
+hardware blocks.
+
+Required properties:
+- #address-cells : should be 1.
+- #size-cells : should be 1.
+- compatible : "nuvoton,npcm750-pinctrl" for Poleg NPCM7XX.
+- ranges : defines mapping ranges between pin controller node (parent)
+ to GPIO bank node (children).
+
+=== GPIO Bank Subnode ===
+
+The NPCM7XX has 8 GPIO Banks each GPIO bank supports 32 GPIO.
+
+Required GPIO Bank subnode-properties:
+- reg : specifies physical base address and size of the GPIO
+ bank registers.
+- gpio-controller : Marks the device node as a GPIO controller.
+- #gpio-cells : Must be <2>. The first cell is the gpio pin number
+ and the second cell is used for optional parameters.
+- interrupts : contain the GPIO bank interrupt with flags for falling edge.
+- gpio-ranges : defines the range of pins managed by the GPIO bank controller.
+
+For example, GPIO bank subnodes like the following:
+ gpio0: gpio@f0010000 {
+ gpio-controller;
+ #gpio-cells = <2>;
+ reg = <0x0 0x80>;
+ interrupts = <GIC_SPI 116 IRQ_TYPE_LEVEL_HIGH>;
+ gpio-ranges = <&pinctrl 0 0 32>;
+ };
+
+=== Pin Mux Subnode ===
+
+- pin: A string containing the name of the pin
+ An array of strings, each string containing the name of a pin.
+ These pin are used for selecting pin configuration.
+
+The following are the list of pins available:
+ "GPIO0/IOX1DI", "GPIO1/IOX1LD", "GPIO2/IOX1CK", "GPIO3/IOX1D0",

+
+Required pin group subnode-properties:
+- groups : A string containing the name of the group to mux.
+- function: A string containing the name of the function to mux to the
+ group.
+
+The following are the list of the available groups and functions :
+ smb0, smb0b, smb0c, smb0d, smb0den, smb1, smb1b, smb1c, smb1d,
+ smb2, smb2b, smb2c, smb2d, smb3, smb3b, smb3c, smb3d, smb4, smb4b,

+
+For example, pinctrl might have group subnodes like the following:
+ r1err_pins: r1err-pins {
+ groups = "r1err";
+ function = "r1err";
+ };
+ r1md_pins: r1md-pins {

+description: |
+ Please refer to pinctrl-bindings.txt in this directory for details of the
+ common pinctrl bindings used by client devices, including the meaning of
+ the phrase "pin configuration node".
+
+ Tegra's pin configuration nodes act as a container for an arbitrary number
+ of subnodes. Each of these subnodes represents some desired configuration
+ for a pin, a group, or a list of pins or groups. This configuration can
+ include the mux function to select on those pin(s)/ group(s), and various
+ pin configuration parameters, such as pull-up, tristate, drive strength,
+ etc.
+
+ The name of each subnode is not important; all subnodes should be
+ enumerated and processed purely based on their content.
+
+ Each subnode only affects those parameters that are explicitly listed. In
+ other words, a subnode that lists a mux function but no pin configuration
+ parameters implies no information about any pin configuration parameters.
+
+ Similarly, a pin subnode that describes a pullup parameter implies no
+ information about e.g. the mux function or tristate parameter. For this
+ reason, even seemingly boolean values are actually tristates in this
+ binding: unspecified, off, or on. Unspecified is represented as an absent
+ property, and off/on are represented as integer values 0 and 1.
+
+ Note that many of these properties are only valid for certain specific pins
+ or groups. See the Tegra TRM and various pinmux spreadsheets for complete
+ details regarding which groups support which functionality. The Linux
+ pinctrl driver may also be a useful reference, since it consolidates,
+ disambiguates, and corrects data from all those sources.

+Device tree binding for NVIDIA Tegra XUSB pad controller
+========================================================
+
+NOTE: It turns out that this binding isn't an accurate description of the XUSB
+pad controller. While the description is good enough for the functional subset
+required for PCIe and SATA, it lacks the flexibility to represent the features
+needed for USB. For the new binding, see ../phy/nvidia,tegra-xusb-padctl.txt.
+The binding described in this file is deprecated and should not be used.
+
+The Tegra XUSB pad controller manages a set of lanes, each of which can be
+assigned to one out of a set of different pads. Some of these pads have an
+associated PHY that must be powered up before the pad can be used.
+
+This document defines the device-specific binding for the XUSB pad controller.
+
+Refer to pinctrl-bindings.txt in this directory for generic information about
+pin controller device tree bindings and ../phy/phy-bindings.txt for details on
+how to describe and reference PHYs in device trees.
+
+Required properties:
+--------------------
+- compatible: For Tegra124, must contain "nvidia,tegra124-xusb-padctl".
+ Otherwise, must contain '"nvidia,<chip>-xusb-padctl",
+ "nvidia-tegra124-xusb-padctl"', where <chip> is tegra132 or tegra210.
+- reg: Physical base address and length of the controller's registers.
+- resets: Must contain an entry for each entry in reset-names.
+ See ../reset/reset.txt for details.
+- reset-names: Must include the following entries:
+ - padctl
+- #phy-cells: Should be 1. The specifier is the index of the PHY to reference.
+ See <dt-bindings/pinctrl/pinctrl-tegra-xusb.h> for the list of valid values.
+
+Lane muxing:
+------------
+
+Child nodes contain the pinmux configurations following the conventions from
+the pinctrl-bindings.txt document. Typically a single, static configuration is
+given and applied at boot time.
+
+Each subnode describes groups of lanes along with parameters and pads that
+they should be assigned to. The name of these subnodes is not important. All
+subnodes should be parsed solely based on their content.
+
+Each subnode only applies the parameters that are explicitly listed. In other
+words, if a subnode that lists a function but no pin configuration parameters
+implies no information about any pin configuration parameters. Similarly, a
+subnode that describes only an IDDQ parameter implies no information about
+what function the pins are assigned to. For this reason even seemingly boolean
+values are actually tristates in this binding: unspecified, off or on.
+Unspecified is represented as an absent property, and off/on are represented
+as integer values 0 and 1.
+
+Required properties:
+- nvidia,lanes: An array of strings. Each string is the name of a lane.
+
+Optional properties:
+- nvidia,function: A string that is the name of the function (pad) that the
+ pin or group should be assigned to. Valid values for function names are
+ listed below.
+- nvidia,iddq: Enables IDDQ mode of the lane. (0: no, 1: yes)
+
+Note that not all of these properties are valid for all lanes. Lanes can be
+divided into three groups:
+
+ - otg-0, otg-1, otg-2:
+
+ Valid functions for this group are: "snps", "xusb", "uart", "rsvd".
+
+ The nvidia,iddq property does not apply to this group.
+
+ - ulpi-0, hsic-0, hsic-1:
+
+ Valid functions for this group are: "snps", "xusb".
+
+ The nvidia,iddq property does not apply to this group.
+
+ - pcie-0, pcie-1, pcie-2, pcie-3, pcie-4, sata-0:
+
+ Valid functions for this group are: "pcie", "usb3", "sata", "rsvd".

+NXP LPC18xx/43xx SCU pin controller Device Tree Bindings
+--------------------------------------------------------
+
+Required properties:
+- compatible : Should be "nxp,lpc1850-scu"
+- reg : Address and length of the register set for the device
+- clocks : Clock specifier (see clock bindings for details)
+
+The lpc1850-scu driver uses the generic pin multiplexing and generic pin
+configuration documented in pinctrl-bindings.txt.
+
+The following generic nodes are supported:
+ - function
+ - pins
+ - bias-disable
+ - bias-pull-up
+ - bias-pull-down
+ - drive-strength
+ - input-enable
+ - input-disable
+ - input-schmitt-enable
+ - input-schmitt-disable
+ - slew-rate
+
+NXP specific properties:
+ - nxp,gpio-pin-interrupt : Assign pin to gpio pin interrupt controller
+ irq number 0 to 7. See example below.
+
+Not all pins support all properties so either refer to the NXP 1850/4350
+user manual or the pin table in the pinctrl-lpc18xx driver for supported
+pin properties.
+
+Example:
+pinctrl: pinctrl@40086000 {

+== Introduction ==
+
+Hardware modules that control pin multiplexing or configuration parameters
+such as pull-up/down, tri-state, drive-strength etc are designated as pin
+controllers. Each pin controller must be represented as a node in device tree,
+just like any other hardware module.
+
+Hardware modules whose signals are affected by pin configuration are
+designated client devices. Again, each client device must be represented as a
+node in device tree, just like any other hardware module.
+
+For a client device to operate correctly, certain pin controllers must
+set up certain specific pin configurations. Some client devices need a
+single static pin configuration, e.g. set up during initialization. Others
+need to reconfigure pins at run-time, for example to tri-state pins when the
+device is inactive. Hence, each client device can define a set of named
+states. The number and names of those states is defined by the client device's
+own binding.
+
+The common pinctrl bindings defined in this file provide an infrastructure
+for client device device tree nodes to map those state names to the pin
+configuration used by those states.
+
+Note that pin controllers themselves may also be client devices of themselves.
+For example, a pin controller may set up its own "active" state when the
+driver loads. This would allow representing a board's static pin configuration
+in a single place, rather than splitting it across multiple client device
+nodes. The decision to do this or not somewhat rests with the author of
+individual board device tree files, and any requirements imposed by the
+bindings for the individual client devices in use by that board, i.e. whether
+they require certain specific named states for dynamic pin configuration.
+
+== Pinctrl client devices ==
+
+For each client device individually, every pin state is assigned an integer
+ID. These numbers start at 0, and are contiguous. For each state ID, a unique
+property exists to define the pin configuration. Each state may also be
+assigned a name. When names are used, another property exists to map from
+those names to the integer IDs.
+
+Each client device's own binding determines the set of states that must be
+defined in its device tree node, and whether to define the set of state
+IDs that must be provided, or whether to define the set of state names that
+must be provided.
+
+Required properties:
+pinctrl-0: List of phandles, each pointing at a pin configuration
+ node. These referenced pin configuration nodes must be child
+ nodes of the pin controller that they configure. Multiple
+ entries may exist in this list so that multiple pin
+ controllers may be configured, or so that a state may be built
+ from multiple nodes for a single pin controller, each
+ contributing part of the overall configuration. See the next
+ section of this document for details of the format of these
+ pin configuration nodes.
+
+ In some cases, it may be useful to define a state, but for it
+ to be empty. This may be required when a common IP block is
+ used in an SoC either without a pin controller, or where the
+ pin controller does not affect the HW module in question. If
+ the binding for that IP block requires certain pin states to
+ exist, they must still be defined, but may be left empty.
+
+Optional properties:
+pinctrl-1: List of phandles, each pointing at a pin configuration
+ node within a pin controller.
+...
+pinctrl-n: List of phandles, each pointing at a pin configuration
+ node within a pin controller.
+pinctrl-names: The list of names to assign states. List entry 0 defines the
+ name for integer state ID 0, list entry 1 for state ID 1, and
+ so on.
+
+For example:
+
+ /* For a client device requiring named states */
+ device {
+ pinctrl-names = "active", "idle";
+ pinctrl-0 = <&state_0_node_a>;
+ pinctrl-1 = <&state_1_node_a>, <&state_1_node_b>;
+ };
+
+ /* For the same device if using state IDs */
+ device {
+ pinctrl-0 = <&state_0_node_a>;
+ pinctrl-1 = <&state_1_node_a>, <&state_1_node_b>;
+ };
+
+ /*
+ * For an IP block whose binding supports pin configuration,
+ * but in use on an SoC that doesn't have any pin control hardware
+ */
+ device {
+ pinctrl-names = "active", "idle";
+ pinctrl-0 = <>;
+ pinctrl-1 = <>;
+ };

+ - "microchip,mcp23018" for 16 GPIO I2C version
+ NOTE: Do not use the old mcp prefix any more. It is deprecated and will be
+ removed.
+- #gpio-cells : Should be two.
+ - first cell is the pin number
+ - second cell is used to specify flags as described in
+ 'Documentation/devicetree/bindings/gpio/gpio.txt'. Allowed values defined by
+ 'include/dt-bindings/gpio/gpio.h' (e.g. GPIO_ACTIVE_LOW).
+- gpio-controller : Marks the device node as a GPIO controller.
+- reg : For an address on its bus. I2C uses this a the I2C address of the chip.
+ SPI uses this to specify the chipselect line which the chip is
+ connected to. The driver and the SPI variant of the chip support
+ multiple chips on the same chipselect. Have a look at
+ microchip,spi-present-mask below.
+
+Required device specific properties (only for SPI chips):
+- mcp,spi-present-mask (DEPRECATED)
+- microchip,spi-present-mask : This is a present flag, that makes only sense for SPI
+ chips - as the name suggests. Multiple SPI chips can share the same
+ SPI chipselect. Set a bit in bit0-7 in this mask to 1 if there is a
+ chip connected with the corresponding spi address set. For example if
+ you have a chip with address 3 connected, you have to set bit3 to 1,
+ which is 0x08. mcp23s08 chip variant only supports bits 0-3. It is not
+ possible to mix mcp23s08 and mcp23s17 on the same chipselect. Set at
+ least one bit to 1 for SPI chips.
+ NOTE: Do not use the old mcp prefix any more. It is deprecated and will be
+ removed.
+- spi-max-frequency = The maximum frequency this chip is able to handle
+
+Optional properties:
+- #interrupt-cells : Should be two.
+ - first cell is the pin number
+ - second cell is used to specify flags.
+- interrupt-controller: Marks the device node as a interrupt controller.
+- drive-open-drain: Sets the ODR flag in the IOCON register. This configures
+ the IRQ output as open drain active low.
+- reset-gpios: Corresponds to the active-low RESET# pin for the chip
+
+Optional device specific properties:
+- microchip,irq-mirror: Sets the mirror flag in the IOCON register. Devices
+ with two interrupt outputs (these are the devices ending with 17 and
+ those that have 16 IOs) have two IO banks: IO 0-7 form bank 1 and
+ IO 8-15 are bank 2. These chips have two different interrupt outputs:
+ One for bank 1 and another for bank 2. If irq-mirror is set, both
+ interrupts are generated regardless of the bank that an input change
+ occurred on. If it is not set, the interrupt are only generated for the
+ bank they belong to.
+ On devices with only one interrupt output this property is useless.
+- microchip,irq-active-high: Sets the INTPOL flag in the IOCON register. This
+ configures the IRQ output polarity as active high.
+
+Example I2C (with interrupt):
+gpiom1: gpio@20 {
+ compatible = "microchip,mcp23017";
+ gpio-controller;
+ #gpio-cells = <2>;
+ reg = <0x20>;
+
+ interrupt-parent = <&gpio1>;
+ interrupts = <17 IRQ_TYPE_LEVEL_LOW>;
+ interrupt-controller;
+ #interrupt-cells=<2>;
+ microchip,irq-mirror;

+ #gpio-cells = <2>;
+ microchip,spi-present-mask = <0x01>;
+ reg = <0>;
+ spi-max-frequency = <1000000>;

+Pull-up configuration
+=====================
+
+If pins are used as output, they can also be configured with pull-ups. This is
+done with pinctrl.

+Palmas Pincontrol bindings
+
+The pins of Palmas device can be set on different option and provides
+the configuration for Pull UP/DOWN, open drain etc.
+
+Required properties:
+- compatible: It must be one of following:
+ - "ti,palmas-pinctrl" for Palma series of the pincontrol.
+ - "ti,tps65913-pinctrl" for Palma series device TPS65913.
+ - "ti,tps80036-pinctrl" for Palma series device TPS80036.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Palmas's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+list of pins. This configuration can include the mux function to select on
+those pin(s), and various pin configuration parameters, such as pull-up,
+open drain.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+Optional properties:
+- ti,palmas-enable-dvfs1: Enable DVFS1. Configure pins for DVFS1 mode.
+ Selection primary or secondary function associated to I2C2_SCL_SCE,
+ I2C2_SDA_SDO pin/pad for DVFS1 interface
+- ti,palmas-enable-dvfs2: Enable DVFS2. Configure pins for DVFS2 mode.
+ Selection primary or secondary function associated to GPADC_START
+ and SYSEN2 pin/pad for DVFS2 interface
+- ti,palmas-override-powerhold: This is applicable for PMICs for which
+ GPIO7 is configured in POWERHOLD mode which has higher priority
+ over DEV_ON bit and keeps the PMIC supplies on even after the DEV_ON
+ bit is turned off. This property enables driver to over ride the
+ POWERHOLD value to GPIO7 so as to turn off the PMIC in power off
+ scenarios. So for GPIO7 if ti,palmas-override-powerhold is set
+ then the GPIO_7 field should never be muxed to anything else.
+ It should be set to POWERHOLD by default and only in case of
+ power off scenarios the driver will over ride the mux value.
+
+This binding uses the following generic properties as defined in
+pinctrl-bindings.txt:
+
+Required: pins
+Options: function, bias-disable, bias-pull-up, bias-pull-down,
+ drive-open-drain.
+
+Note that many of these properties are only valid for certain specific pins.
+See the Palmas device datasheet for complete details regarding which pins
+support which functionality.
+
+Valid values for pin names are:
+ gpio0, gpio1, gpio2, gpio3, gpio4, gpio5, gpio6, gpio7, gpio8, gpio9,
+ gpio10, gpio11, gpio12, gpio13, gpio14, gpio15, vac, powergood,
+ nreswarm, pwrdown, gpadc_start, reset_in, nsleep, enable1, enable2,
+ int.
+
+Valid value of function names are:
+ gpio, led, pwm, regen, sysen, clk32kgaudio, id, vbus_det, chrg_det,
+ vac, vacok, powergood, usb_psel, msecure, pwrhold, int, nreswarm,
+ simrsto, simrsti, low_vbat, wireless_chrg1, rcm, pwrdown, gpadc_start,
+ reset_in, nsleep, enable.
+
+There are 4 special functions: opt0, opt1, opt2 and opt3. If any of these
+functions is selected then directly pins register will be written with 0, 1, 2
+or 3 respectively if it is valid for that pins or list of pins.
+
+Example:
+ palmas: tps65913 {
+ ....
+ pinctrl {
+ compatible = "ti,tps65913-pinctrl";
+ ti,palmas-enable-dvfs1;
+ pinctrl-names = "default";

+*ST pin controller.
+
+Each multi-function pin is controlled, driven and routed through the
+PIO multiplexing block. Each pin supports GPIO functionality (ALT0)
+and multiple alternate functions(ALT1 - ALTx) that directly connect
+the pin to different hardware blocks.
+
+When a pin is in GPIO mode, Output Enable (OE), Open Drain(OD), and
+Pull Up (PU) are driven by the related PIO block.
+
+ST pinctrl driver controls PIO multiplexing block and also interacts with
+gpio driver to configure a pin.
+
+GPIO bank can have one of the two possible types of interrupt-wirings.
+
+First type is via irqmux, single interrupt is used by multiple gpio banks. This
+reduces number of overall interrupts numbers required. All these banks belong to
+a single pincontroller.
+ _________
+ | |----> [gpio-bank (n) ]
+ | |----> [gpio-bank (n + 1)]
+ [irqN]-- | irq-mux |----> [gpio-bank (n + 2)]
+ | |----> [gpio-bank (... )]
+ |_________|----> [gpio-bank (n + 7)]
+
+Second type has a dedicated interrupt per gpio bank.
+
+ [irqN]----> [gpio-bank (n)]
+
+
+Pin controller node:
+Required properties:
+- compatible : should be "st,stih407-<pio-block>-pinctrl"
+- st,syscfg : Should be a phandle of the syscfg node.
+- st,retime-pin-mask : Should be mask to specify which pins can be retimed.
+ If the property is not present, it is assumed that all the pins in the
+ bank are capable of retiming. Retiming is mainly used to improve the
+ IO timing margins of external synchronous interfaces.
+- ranges : defines mapping between pin controller node (parent) to gpio-bank
+ node (children).
+
+Optional properties:
+- interrupts : Interrupt number of the irqmux. If the interrupt is shared
+ with other gpio banks via irqmux.
+ a irqline and gpio banks.
+- reg : irqmux memory resource. If irqmux is present.
+- reg-names : irqmux resource should be named as "irqmux".
+
+GPIO controller/bank node.
+Required properties:
+- gpio-controller : Indicates this device is a GPIO controller
+- #gpio-cells : Must be two.
+ - First cell: specifies the pin number inside the controller
+ - Second cell: specifies whether the pin is logically inverted.
+ - 0 = active high
+ - 1 = active low
+- st,bank-name : Should be a name string for this bank as specified in
+ datasheet.
+
+Optional properties:
+- interrupts : Interrupt number for this gpio bank. If there is a dedicated
+ interrupt wired up for this gpio bank.
+
+- interrupt-controller : Indicates this device is a interrupt controller. GPIO
+ bank can be an interrupt controller iff one of the interrupt type either via
+irqmux or a dedicated interrupt per bank is specified.
+
+- #interrupt-cells: the value of this property should be 2.
+ - First Cell: represents the external gpio interrupt number local to the
+ gpio interrupt space of the controller.
+ - Second Cell: flags to identify the type of the interrupt
+ - 1 = rising edge triggered
+ - 2 = falling edge triggered
+ - 3 = rising and falling edge triggered

+VIA VT8500 and Wondermedia WM8xxx-series pinmux/gpio controller
+
+These SoCs contain a combined Pinmux/GPIO module. Each pin may operate as
+either a GPIO in, GPIO out or as an alternate function (I2C, SPI etc).
+
+Required properties:
+- compatible: "via,vt8500-pinctrl", "wm,wm8505-pinctrl", "wm,wm8650-pinctrl",
+ "wm8750-pinctrl" or "wm,wm8850-pinctrl"
+- reg: Should contain the physical address of the module's registers.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be two.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two. The first cell is the pin number and the
+ second cell is used to specify optional parameters.
+ bit 0 - active low
+
+Please refer to ../gpio/gpio.txt for a general description of GPIO bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Each pin configuration node lists the pin(s) to which it applies, and one or
+more of the mux functions to select on those pin(s), and pull-up/down
+configuration. Each subnode only affects those parameters that are explicitly
+listed. In other words, a subnode that lists only a mux function implies no
+information about any pull configuration. Similarly, a subnode that lists only
+a pull parameter implies no information about the mux function.
+
+Required subnode-properties:
+- wm,pins: An array of cells. Each cell contains the ID of a pin.
+
+Optional subnode-properties:
+- wm,function: Integer, containing the function to mux to the pin(s):
+ 0: GPIO in
+ 1: GPIO out
+ 2: alternate
+
+- wm,pull: Integer, representing the pull-down/up to apply to the pin(s):
+ 0: none
+ 1: down
+ 2: up
+
+Each of wm,function and wm,pull may contain either a single value which
+will be applied to all pins in wm,pins, or one value for each entry in
+wm,pins.
+
+Example:
+
+ pinctrl: pinctrl {
+ compatible = "wm,wm8505-pinctrl";
+ reg = <0xD8110000 0x10000>;
+ interrupt-controller;
+ #interrupt-cells = <2>;

+title: Generic Pin Multiplexing Node
+
+maintainers:
+ - Linus Walleij <linus.walleij@linaro.org>
+
+description: |
+ The contents of the pin configuration child nodes are defined by the binding
+ for the individual pin controller device. The pin configuration nodes need not
+ be direct children of the pin controller device; they may be grandchildren,
+ for example. Whether this is legal, and whether there is any interaction
+ between the child and intermediate parent nodes, is again defined entirely by
+ the binding for the individual pin controller device.
+
+ While not required to be used, there are 3 generic forms of pin muxing nodes
+ which pin controller devices can use.
+
+ pin multiplexing nodes:
+
+ Example:
+
+ state_0_node_a {
+ uart0 {
+ function = "uart0";
+ groups = "u0rxtx", "u0rtscts";
+ };
+ };
+ state_1_node_a {
+ spi {
+ function = "spi0";
+ groups = "spi0pins";
+ };
+ };
+ state_2_node_a {
+ function = "i2c0";
+ pins = "mfio29", "mfio30";
+ };
+
+ Optionally an alternative binding can be used if more suitable depending on the
+ pin controller hardware. For hardware where there is a large number of identical
+ pin controller instances, naming each pin and function can easily become
+ unmaintainable. This is especially the case if the same controller is used for
+ different pins and functions depending on the SoC revision and packaging.
+
+ For cases like this, the pin controller driver may use pinctrl-pin-array helper
+ binding with a hardware based index and a number of pin configuration values:
+
+ pincontroller {
+ ... /* Standard DT properties for the device itself elided */
+ #pinctrl-cells = <2>;
+
+ state_0_node_a {
+ pinctrl-pin-array = <
+ 0 A_DELAY_PS(0) G_DELAY_PS(120)
+ 4 A_DELAY_PS(0) G_DELAY_PS(360)
+ ...
+ >;
+ };
+ ...
+ };
+
+ Above #pinctrl-cells specifies the number of value cells in addition to the
+ index of the registers. This is similar to the interrupts-extended binding with
+ one exception. There is no need to specify the phandle for each entry as that
+ is already known as the defined pins are always children of the pin controller
+ node. Further having the phandle pointing to another pin controller would not
+ currently work as the pinctrl framework uses named modes to group pins for each
+ pin control device.
+
+ The index for pinctrl-pin-array must relate to the hardware for the pinctrl
+ registers, and must not be a virtual index of pin instances. The reason for
+ this is to avoid mapping of the index in the dts files and the pin controller
+ driver as it can change.
+
+ For hardware where pin multiplexing configurations have to be specified for
+ each single pin the number of required sub-nodes containing "pin" and
+ "function" properties can quickly escalate and become hard to write and
+ maintain.
+
+ For cases like this, the pin controller driver may use the pinmux helper
+ property, where the pin identifier is provided with mux configuration settings
+ in a pinmux group. A pinmux group consists of the pin identifier and mux
+ settings represented as a single integer or an array of integers.
+
+ The pinmux property accepts an array of pinmux groups, each of them describing
+ a single pin multiplexing configuration.
+
+ pincontroller {
+ state_0_node_a {
+ pinmux = <PINMUX_GROUP>, <PINMUX_GROUP>, ...;
+ };
+ };
+
+ Each individual pin controller driver bindings documentation shall specify
+ how pin IDs and pin multiplexing configuration are defined and assembled
+ together in a pinmux group.

+
+Qualcomm's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid

+Qualcomm IPQ8064 TLMM block
+
+Required properties:
+- compatible: "qcom,ipq8064-pinctrl"
+- reg: Should be the base address and length of the TLMM block.
+- interrupts: Should be the parent IRQ of the TLMM block.
+- interrupt-controller: Marks the device node as an interrupt controller.
+- #interrupt-cells: Should be two.
+- gpio-controller: Marks the device node as a GPIO controller.
+- #gpio-cells : Should be two.
+ The first cell is the gpio pin number and the
+ second cell is used for optional parameters.
+- gpio-ranges: see ../gpio/gpio.txt
+
+Optional properties:
+
+- gpio-reserved-ranges: see ../gpio/gpio.txt
+
+Please refer to ../gpio/gpio.txt and ../interrupt-controller/interrupts.txt for
+a general description of GPIO and interrupt bindings.
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+Qualcomm's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as pull-up, drive strength, etc.
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content.
+
+Each subnode only affects those parameters that are explicitly listed. In
+other words, a subnode that lists a mux function but no pin configuration
+parameters implies no information about any pin configuration parameters.
+Similarly, a pin subnode that describes a pullup parameter implies no
+information about e.g. the mux function.
+
+
+The following generic properties as defined in pinctrl-bindings.txt are valid
+to specify in a pin configuration subnode:
+
+ pins, function, bias-disable, bias-pull-down, bias-pull-up, drive-strength,
+ output-low, output-high.
+
+Non-empty subnodes must specify the 'pins' property.
+
+Valid values for qcom,pins are:
+ gpio0-gpio68
+ Supports mux, bias, and drive-strength
+
+ sdc3_clk, sdc3_cmd, sdc3_data
+ Supports bias and drive-strength
+
+
+Valid values for function are:
+ mdio, mi2s, pdm, ssbi, spmi, audio_pcm, gpio, gsbi1, gsbi2, gsbi4, gsbi5,
+ gsbi5_spi_cs1, gsbi5_spi_cs2, gsbi5_spi_cs3, gsbi6, gsbi7, nss_spi, sdc1,
+ spdif, nand, tsif1, tsif2, usb_fs_n, usb_fs, usb2_hsic, rgmii2, sata,
+ pcie1_rst, pcie1_prsnt, pcie1_pwren_n, pcie1_pwren, pcie1_pwrflt,
+ pcie1_clk_req, pcie2_rst, pcie2_prsnt, pcie2_pwren_n, pcie2_pwren,
+ pcie2_pwrflt, pcie2_clk_req, pcie3_rst, pcie3_prsnt, pcie3_pwren_n,
+ pcie3_pwren, pcie3_pwrflt, pcie3_clk_req, ps_hold
+
+Example:
+
+ pinmux: pinctrl@800000 {
+ compatible = "qcom,ipq8064-pinctrl";
+ reg = <0x800000 0x4000>;

+ A pin multiplexing sub-node describes how to configure a set of (or a

+ A single sub-node may define several pin configurations.
+ A few alternate function require special pin configuration flags to be
+ supplied along with the alternate function configuration number.

+ "software IO driven" mode to be specified. To do so use the generic
+ properties from the <include/linux/pinctrl/pinconf_generic.h> header
+ file to instruct the pin controller to perform the desired pin
+ configuration operation.
+ The hardware reference manual specifies when a pin has to be configured
+ to work in bi-directional mode and when the IO direction has to be

+ controller driver internally, while software driven IO direction has to

+ options with option 0 being used as a GPIO.
+
+ Please refer to pinctrl-bindings.txt in this directory for details of the
+ common pinctrl bindings used by client devices, including the meaning of the
+ phrase "pin configuration node".
+
+ The Rockchip pin configuration node is a node of a group of pins which can be
+ used for a specific device or function. This node represents both mux and
+ config of the pins in that group. The 'pins' selects the function mode
+ (also named pin mode) this pin can work on and the 'config' configures
+ various pad settings such as pull-up, etc.
+
+ The pins are grouped into up to 9 individual pin banks which need to be
+ defined as gpio sub-nodes of the pinmux controller.

+* Spreadtrum Pin Controller
+
+The Spreadtrum pin controller are organized in 3 blocks (types).
+
+The first block comprises some global control registers, and each
+register contains several bit fields with one bit or several bits
+to configure for some global common configuration, such as domain
+pad driving level, system control select and so on ("domain pad
+driving level": One pin can output 3.0v or 1.8v, depending on the
+related domain pad driving selection, if the related domain pad
+select 3.0v, then the pin can output 3.0v. "system control" is used
+to choose one function (like: UART0) for which system, since we
+have several systems (AP/CP/CM4) on one SoC.).
+
+There are too much various configuration that we can not list all
+of them, so we can not make every Spreadtrum-special configuration
+as one generic configuration, and maybe it will add more strange
+global configuration in future. Then we add one "sprd,control" to
+set these various global control configuration, and we need use
+magic number for this property.
+
+Moreover we recognise every fields comprising one bit or several
+bits in one global control register as one pin, thus we should
+record every pin's bit offset, bit width and register offset to
+configure this field (pin).
+
+The second block comprises some common registers which have unified
+register definition, and each register described one pin is used
+to configure the pin sleep mode, function select and sleep related
+configuration.
+
+Now we have 4 systems for sleep mode on SC9860 SoC: AP system,
+PUBCP system, TGLDSP system and AGDSP system. And the pin sleep
+related configuration are:
+- input-enable
+- input-disable
+- output-high
+- output-low
+- bias-pull-up
+- bias-pull-down
+
+In some situation we need set the pin sleep mode and pin sleep related
+configuration, to set the pin sleep related configuration automatically
+by hardware when the system specified by sleep mode goes into deep
+sleep mode. For example, if we set the pin sleep mode as PUBCP_SLEEP
+and set the pin sleep related configuration as "input-enable", which
+means when PUBCP system goes into deep sleep mode, this pin will be set
+input enable automatically.
+
+Moreover we can not use the "sleep" state, since some systems (like:
+PUBCP system) do not run linux kernel OS (only AP system run linux
+kernel on SC9860 platform), then we can not select "sleep" state
+when the PUBCP system goes into deep sleep mode. Thus we introduce
+"sprd,sleep-mode" property to set pin sleep mode.
+
+The last block comprises some misc registers which also have unified
+register definition, and each register described one pin is used to
+configure drive strength, pull up/down and so on. Especially for pull
+up, we have two kind pull up resistor: 20K and 4.7K.
+
+Required properties for Spreadtrum pin controller:
+- compatible: "sprd,<soc>-pinctrl"
+ Please refer to each sprd,<soc>-pinctrl.txt binding doc for supported SoCs.
+- reg: The register address of pin controller device.
+- pins : An array of pin names.
+
+Optional properties:
+- function: Specified the function name.
+- drive-strength: Drive strength in mA.
+- input-schmitt-disable: Enable schmitt-trigger mode.
+- input-schmitt-enable: Disable schmitt-trigger mode.
+- bias-disable: Disable pin bias.
+- bias-pull-down: Pull down on pin.
+- bias-pull-up: Pull up on pin.
+- input-enable: Enable pin input.
+- input-disable: Enable pin output.
+- output-high: Set the pin as an output level high.
+- output-low: Set the pin as an output level low.
+- sleep-hardware-state: Indicate these configs in this state are sleep related.
+- sprd,control: Control values referring to databook for global control pins.
+- sprd,sleep-mode: Sleep mode selection.
+
+Please refer to each sprd,<soc>-pinctrl.txt binding doc for supported values.

+description: |
+ Bindings for the JH7100 RISC-V SoC from StarFive Ltd.
+
+ Out of the SoC's many pins only the ones named PAD_GPIO[0] to PAD_GPIO[63]
+ and PAD_FUNC_SHARE[0] to PAD_FUNC_SHARE[141] can be multiplexed and have
+ configurable bias, drive strength, schmitt trigger etc. The SoC has an
+ interesting 2-layered approach to pin muxing best illustrated by the diagram
+ below.
+
+ Signal group 0, 1, ... or 6
+ ___|___

+ LCD output -----------------| |
+ CMOS Camera interface ------| |--- PAD_GPIO[0]
+ Ethernet PHY interface -----| MUX |--- PAD_GPIO[1]

+ | | | | | |--- PAD_FUNC_SHARE[141]
+ | | -----|---|-- GPIO63 ---| |
+ | | | | | | -------
+ UART0 UART1 --
+
+
+ The big MUX in the diagram only has 7 different ways of mapping peripherals
+ on the left to pins on the right. StarFive calls the 7 configurations "signal
+ groups".
+ However some peripherals have their I/O go through the 64 "GPIOs". The
+ diagram only shows UART0 and UART1, but this also includes a number of other
+ UARTs, I2Cs, SPIs, PWMs etc. All these peripherals are connected to all 64
+ GPIOs such that any GPIO can be set up to be controlled by any of the
+ peripherals.
+ Note that signal group 0 doesn't map any of the GPIOs to pins, and only
+ signal group 1 maps the GPIOs to the pins named PAD_GPIO[0] to PAD_GPIO[63].

+ST Ericsson Nomadik pinmux controller
+
+Required properties:
+- compatible: "stericsson,db8500-pinctrl", "stericsson,db8540-pinctrl",
+ "stericsson,stn8815-pinctrl"
+- nomadik-gpio-chips: array of phandles to the corresponding GPIO chips
+ (these have the register ranges used by the pin controller).
+- prcm: phandle to the PRCMU managing the back end of this pin controller
+
+Please refer to pinctrl-bindings.txt in this directory for details of the
+common pinctrl bindings used by client devices, including the meaning of the
+phrase "pin configuration node".
+
+ST Ericsson's pin configuration nodes act as a container for an arbitrary number of
+subnodes. Each of these subnodes represents some desired configuration for a
+pin, a group, or a list of pins or groups. This configuration can include the
+mux function to select on those pin(s)/group(s), and various pin configuration
+parameters, such as input, output, pull up, pull down...
+
+The name of each subnode is not important; all subnodes should be enumerated
+and processed purely based on their content. The subnodes use the generic
+pin multiplexing node layout from the standard pin control bindings
+(see pinctrl-bindings.txt):
+
+Required pin multiplexing subnode properties:
+- function: A string containing the name of the function to mux to the
+ pin or group.
+- groups : An array of strings. Each string contains the name of a pin
+ group that will be combined with the function to form a multiplexing
+ set-up.
+
+Required pin configuration subnode properties:
+- pins: A string array describing the pins affected by the configuration
+ in the node.
+- ste,config: Handle of pin configuration node
+ (e.g. ste,config = <&slpm_in_wkup_pdis>)
+
+- ste,input : <0/1/2>
+ 0: input with no pull
+ 1: input with pull up,
+ 2: input with pull down,
+
+- ste,output: <0/1/2>
+ 0: output low,
+ 1: output high,
+ 2: output (value is not specified).
+

+ 0: sleep mode disable,
+ 1: sleep mode enable.
+
+- ste,sleep-input: <0/1/2/3>
+ 0: sleep input with no pull,
+ 1: sleep input with pull up,
+ 2: sleep input with pull down.
+ 3: sleep input and keep last input configuration (no pull, pull up or pull down).
+
+- ste,sleep-output: <0/1/2>
+ 0: sleep output low,
+ 1: sleep output high,
+ 2: sleep output (value is not specified).
+
+- ste,sleep-gpio: <0/1>
+ 0: disable sleep gpio mode,
+ 1: enable sleep gpio mode.
+
+- ste,sleep-wakeup: <0/1>
+ 0: wake-up detection enabled,

+
+description: |
+ The Sunplus SP7021 pin controller is used to control SoC pins. Please
+ refer to pinctrl-bindings.txt in this directory for details of the common
+ pinctrl bindings used by client devices.
+
+ SP7021 has 99 digital GPIO pins which are numbered from GPIO 0 to 98. All
+ are multiplexed with some special function pins. SP7021 has 3 types of
+ special function pins:
+
+ (1) function-group pins:
+ Ex 1 (SPI-NOR flash):
+ If control-field SPI_FLASH_SEL is set to 1, GPIO 83, 84, 86 and 87
+ will be pins of SPI-NOR flash. If it is set to 2, GPIO 76, 78, 79
+ and 81 will be pins of SPI-NOR flash.
+
+ Ex 2 (UART_0):
+ If control-bit UA0_SEL is set to 1, GPIO 88 and 89 will be TX and
+ RX pins of UART_0 (UART channel 0).
+
+ Ex 3 (eMMC):
+ If control-bit EMMC_SEL is set to 1, GPIO 72, 73, 74, 75, 76, 77,
+ 78, 79, 80, 81 will be pins of an eMMC device.
+
+ Properties "function" and "groups" are used to select function-group
+ pins.
+
+ (2) fully pin-mux (like phone exchange mux) pins:
+ GPIO 8 to 71 are 'fully pin-mux' pins. Any pins of peripherals of
+ SP7021 (ex: UART_1, UART_2, UART_3, UART_4, I2C_0, I2C_1, and etc.)
+ can be routed to any pins of fully pin-mux pins.
+
+ Ex 1 (UART channel 1):
+ If control-field UA1_TX_SEL is set to 3, TX pin of UART_1 will be
+ routed to GPIO 10 (3 - 1 + 8 = 10).
+ If control-field UA1_RX_SEL is set to 4, RX pin of UART_1 will be
+ routed to GPIO 11 (4 - 1 + 8 = 11).
+ If control-field UA1_RTS_SEL is set to 5, RTS pin of UART_1 will
+ be routed to GPIO 12 (5 - 1 + 8 = 12).
+ If control-field UA1_CTS_SEL is set to 6, CTS pin of UART_1 will
+ be routed to GPIO 13 (6 - 1 + 8 = 13).
+
+ Ex 2 (I2C channel 0):
+ If control-field I2C0_CLK_SEL is set to 20, CLK pin of I2C_0 will
+ be routed to GPIO 27 (20 - 1 + 8 = 27).
+ If control-field I2C0_DATA_SEL is set to 21, DATA pin of I2C_0
+ will be routed to GPIO 28 (21 - 1 + 9 = 28).
+
+ Totally, SP7021 has 120 peripheral pins. The peripheral pins can be
+ routed to any of 64 'fully pin-mux' pins.
+
+ (3) I/O processor pins
+ SP7021 has a built-in I/O processor.
+ Any GPIO pins (GPIO 0 to 98) can be set to pins of I/O processor.
+
+ Vendor property "sunplus,pins" is used to select "fully pin-mux" pins,
+ "I/O processor pins" and "digital GPIO" pins.
+
+ The device node of pin controller of Sunplus SP7021 has following
+ properties.

+
+ Zynq's pin configuration nodes act as a container for an arbitrary number of
+ subnodes. Each of these subnodes represents some desired configuration for a
+ pin, a group, or a list of pins or groups. This configuration can include the
+ mux function to select on those pin(s)/group(s), and various pin configuration

+
+ Each configuration node can consist of multiple nodes describing the pinmux and
+ pinconf options. Those nodes can be pinmux nodes or pinconf nodes.
+
+ The name of each subnode is not important; all subnodes should be enumerated
+ and processed purely based on their content.
