9 depends on DM
10 help
Simon Glassf94a1be2015-02-05 21:41:35 -070011 Enable driver model for GPIO access. The standard GPIO
12 interface (gpio_get_value(), etc.) is then implemented by
13 the GPIO uclass. Drivers provide methods to query the
14 particular GPIOs that they provide. The uclass interface
15 is defined in include/asm-generic/gpio.h.

35 help
36 Say yes here to support the Atmel PIO4 driver.
37 The PIO4 is new version of Atmel PIO controller, which manages
38 up to 128 fully programmable input/output lines. Each I/O line
39 may be dedicated as a general purpose I/O or be assigned to
40 a function of an embedded peripheral.

43 bool "Intel Broadwell GPIO driver"
44 depends on DM
45 help
46 This driver supports Broadwell U devices which have an expanded
47 GPIO feature set. The difference is large enough to merit a separate
48 driver from the common Intel ICH6 driver. It supports a total of
49 95 GPIOs which can be configured from the device tree.

61 default n
62 help
63 Support GPIO controllers on Qualcomm Snapdragon family of SoCs.
64 This controller have single bank (default name "soc"), every
65 gpio has it's own set of registers.
66 Only simple GPIO operations are supported (get/set, change of
67 direction and checking pin function).
68 Supported devices:
69 - APQ8016
70 - MSM8916

74 depends on DM_GPIO
75 help
76 Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
77 a number of banks (different for each SoC type) each with 32 GPIOs.
78 The GPIOs for a device are defined in the device tree with one node
79 for each bank.

82 bool "Enable sandbox GPIO driver"
83 depends on SANDBOX && DM && DM_GPIO
84 help
85 This driver supports some simulated GPIOs which can be adjusted
86 using 'back door' functions like sandbox_gpio_set_value(). Then the
87 GPIOs can be inspected through the normal get_get_value()
88 interface. The purpose of this is to allow GPIOs to be used as
89 normal in sandbox, perhaps with test code actually driving the
90 behaviour of those GPIOs.

92config SANDBOX_GPIO_COUNT
93 int "Number of sandbox GPIOs"
94 depends on SANDBOX_GPIO
95 default 128
96 help
97 The sandbox driver can support any number of GPIOs. Generally these
98 are specified using the device tree. But you can also have a number
99 of 'anonymous' GPIOs that do not belong to any device or bank.
100 Select a suitable value depending on your needs.
