| config PINCTRL |
| bool "Support pin controllers" |
| depends on DM |
| help |
| This enables the basic support for pinctrl framework. You may want |
| to enable some more options depending on what you want to do. |
| |
| config PINCTRL_FULL |
| bool "Support full pin controllers" |
| depends on PINCTRL && OF_CONTROL |
| default y |
| help |
| This provides Linux-compatible device tree interface for the pinctrl |
| subsystem. This feature depends on device tree configuration because |
| it parses a device tree to look for the pinctrl device which the |
| peripheral device is associated with. |
| |
| If this option is disabled (it is the only possible choice for non-DT |
| boards), the pinctrl core provides no systematic mechanism for |
| identifying peripheral devices, applying needed pinctrl settings. |
| It is totally up to the implementation of each low-level driver. |
| You can save memory footprint in return for some limitations. |
| |
| config PINCTRL_GENERIC |
| bool "Support generic pin controllers" |
| depends on PINCTRL_FULL |
| default y |
| help |
| Say Y here if you want to use the pinctrl subsystem through the |
| generic DT interface. If enabled, some functions become available |
| to parse common properties such as "pins", "groups", "functions" and |
| some pin configuration parameters. It would be easier if you only |
| need the generic DT interface for pin muxing and pin configuration. |
| If you need to handle vendor-specific DT properties, you can disable |
| this option and implement your own set_state callback in the pinctrl |
| operations. |
| |
| config PINMUX |
| bool "Support pin multiplexing controllers" |
| depends on PINCTRL_GENERIC |
| default y |
| help |
| This option enables pin multiplexing through the generic pinctrl |
| framework. Most SoCs have their own multiplexing arrangement where |
| a single pin can be used for several functions. An SoC pinctrl driver |
| allows the required function to be selected for each pin. |
| The driver is typically controlled by the device tree. |
| |
| config PINCONF |
| bool "Support pin configuration controllers" |
| depends on PINCTRL_GENERIC |
| help |
| This option enables pin configuration through the generic pinctrl |
| framework. |
| |
| config PINCONF_RECURSIVE |
| bool "Support recursive binding for pin configuration nodes" |
| depends on PINCTRL_FULL |
| default n if ARCH_STM32MP |
| default y |
| help |
| In the Linux pinctrl binding, the pin configuration nodes need not be |
| direct children of the pin controller device (may be grandchildren for |
| example). It is define is each individual pin controller device. |
| Say Y here if you want to keep this behavior with the pinconfig |
| u-class: all sub are recursively bounded. |
| If the option is disabled, this behavior is deactivated and only |
| the direct children of pin controller will be assumed as pin |
| configuration; you can save memory footprint when this feature is |
| no needed. |

| config SPL_PINCTRL |
| bool "Support pin controllers in SPL" |
| depends on SPL && SPL_DM |
| help |
| This option is an SPL-variant of the PINCTRL option. |
| See the help of PINCTRL for details. |
| |
| config TPL_PINCTRL |
| bool "Support pin controllers in TPL" |
| depends on TPL && TPL_DM |
| help |
| This option is an TPL variant of the PINCTRL option. |
| See the help of PINCTRL for details. |

| bool "Support full pin controllers in SPL" |
| depends on SPL_PINCTRL && SPL_OF_CONTROL |

| default y |
| help |
| This option is an SPL-variant of the PINCTRL_GENERIC option. |
| See the help of PINCTRL_GENERIC for details. |
| |
| config SPL_PINMUX |
| bool "Support pin multiplexing controllers in SPL" |
| depends on SPL_PINCTRL_GENERIC |
| default y |
| help |
| This option is an SPL-variant of the PINMUX option. |
| See the help of PINMUX for details. |
| The pinctrl subsystem can add a substantial overhead to the SPL |
| image since it typically requires quite a few tables either in the |
| driver or in the device tree. If this is acceptable and you need |
| to adjust pin multiplexing in SPL in order to boot into U-Boot, |
| enable this option. You will need to enable device tree in SPL |
| for this to work. |
| |
| config SPL_PINCONF |
| bool "Support pin configuration controllers in SPL" |

| config PINCTRL_AT91 |
| bool "AT91 pinctrl driver" |
| depends on DM |
| help |
| This option is to enable the AT91 pinctrl driver for AT91 PIO |
| controller. |
| |
| AT91 PIO controller is a combined gpio-controller, pin-mux and |
| pin-config module. Each I/O pin may be dedicated as a general-purpose |
| I/O or be assigned to a function of an embedded peripheral. Each I/O |
| pin has a glitch filter providing rejection of glitches lower than |
| one-half of peripheral clock cycle and a debouncing filter providing |
| rejection of unwanted pulses from key or push button operations. You |
| can also control the multi-driver capability, pull-up and pull-down |
| feature on each I/O pin. |
| |
| config PINCTRL_AT91PIO4 |

| controller which is available on SAMA5D2 SoC. |

| config PINCTRL_INTEL |
| bool "Standard Intel pin-control and pin-mux driver" |
| help |
| Recent Intel chips such as Apollo Lake (APL) use a common pin control |
| and GPIO scheme. The settings for this come from an SoC-specific |
| driver which must be separately enabled. The driver supports setting |
| pins on start-up and changing the GPIO attributes. |

| help |
| This enables pinctrl driver for sandbox. |
| |
| Currently, this driver actually does nothing but print debug |
| messages when pinctrl operations are invoked. |
| |
| config PINCTRL_SINGLE |
| bool "Single register pin-control and pin-multiplex driver" |
| depends on DM |
| help |
| This enables pinctrl driver for systems using a single register for |
| pin configuration and multiplexing. TI's AM335X SoCs are examples of |
| such systems. |
| |
| Depending on the platform make sure to also enable OF_TRANSLATE and |
| eventually SPL_OF_TRANSLATE to get correct address translations. |
