config DM_GPIO
	bool "Enable Driver Model for GPIO drivers"
	depends on DM
	help
	  Enable driver model for GPIO access. The standard GPIO
	  interface (gpio_get_value(), etc.) is then implemented by
	  the GPIO uclass. Drivers provide methods to query the
	  particular GPIOs that they provide. The uclass interface
	  is defined in include/asm-generic/gpio.h.

	  I/O or be assigned to a function of an embedded peripheral.
	  The assignment to a function of an embedded peripheral is
	  the responsibility of AT91 Pinctrl driver. This driver is
	  responsible for the general-purpose I/O.

config ATMEL_PIO4

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

config OMAP_GPIO
	bool "TI OMAP GPIO driver"
	depends on ARCH_OMAP2PLUS

config CMD_PCA953X
	bool "Enable the pca953x command"
	help
	  Deprecated: This should be converted to driver model.

	  This command provides access to a pca953x GPIO device using the
	  legacy GPIO interface. Several subcommands are provided which mirror
	  the standard 'gpio' command. It should use that instead.

config PM8916_GPIO
	bool "Qualcomm PM8916 PMIC GPIO/keypad driver"
	depends on DM_GPIO && PMIC_PM8916
	help
	  Support for GPIO pins and power/reset buttons found on
	  Qualcomm PM8916 PMIC.

	help
	  Support GPIO access on Rockchip SoCs. The GPIOs are arranged into

	  The GPIOs for a device are defined in the device tree with one node
	  for each bank.

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

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

config TEGRA_GPIO

	  they have slightly different register layout.

config GPIO_UNIPHIER
	bool "UniPhier GPIO"
	depends on ARCH_UNIPHIER
	help
	  Say yes here to support UniPhier GPIOs.

config VYBRID_GPIO
	bool "Vybrid GPIO driver"
	depends on DM
	default n
	help
	  Say yes here to support Vybrid vf610 GPIOs.

	help
	  Driver for 74x164 compatible serial-in/parallel-out 8-outputs
	  shift registers, such as 74lv165, 74hc595.
	  This driver can be used to provide access to more gpio outputs.

config DM_PCA953X
	bool "PCA95[357]x, PCA9698, TCA64xx, and MAX7310 I/O ports"
	depends on DM_GPIO
	help
	  Say yes here to provide access to several register-oriented
	  SMBus I/O expanders, made mostly by NXP or TI.  Compatible
	  models include:

	  4 bits:	pca9536, pca9537

	  8 bits:	max7310, max7315, pca6107, pca9534, pca9538, pca9554,
			pca9556, pca9557, pca9574, tca6408, xra1202

			tca6416

	  24 bits:	tca6424

	  40 bits:	pca9505, pca9698

	  Now, max 24 bits chips and PCA953X compatible chips are
	  supported

config MPC85XX_GPIO
	bool "Freescale MPC85XX GPIO driver"
	depends on DM_GPIO
	help
	  This driver supports the built-in GPIO controller of MPC85XX CPUs.
	  Each GPIO bank is identified by its own entry in the device tree,
	  i.e.

	  gpio-controller@fc00 {
		#gpio-cells = <2>;
		compatible = "fsl,pq3-gpio";
		reg = <0xfc00 0x100>
	  }

	  By default, each bank is assumed to have 32 GPIOs, but the ngpios
	  setting is honored, so the number of GPIOs for each bank is
	  configurable to match the actual GPIO count of the SoC (e.g. the
	  32/32/23 banks of the P1022 SoC).

	  Aside from the standard functions of input/output mode, and output
	  value setting, the open-drain feature, which can configure individual
	  GPIOs to work as open-drain outputs, is supported.

	  The driver has been tested on MPC85XX, but it is likely that other
	  PowerQUICC III devices will work as well.
