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.

config ALTERA_PIO
	bool "Altera PIO driver"
	depends on DM_GPIO
	help
	  Select this to enable PIO for Altera devices. Please find
	  details on the "Embedded Peripherals IP User Guide" of Altera.

config DWAPB_GPIO
	bool "DWAPB GPIO driver"
	depends on DM && DM_GPIO
	default n
	help
	  Support for the Designware APB GPIO driver.

config ATMEL_PIO4
	bool "ATMEL PIO4 driver"
	depends on DM_GPIO
	default n
	help
	  Say yes here to support the Atmel PIO4 driver.
	  The PIO4 is new version of Atmel PIO controller, which manages
	  up to 128 fully programmable input/output lines. Each I/O line
	  may be dedicated as a general purpose I/O or be assigned to
	  a function of an embedded peripheral.

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

config IMX_RGPIO2P
	bool "i.MX7ULP RGPIO2P driver"
	depends on DM
	default n
	help
	  This driver supports i.MX7ULP Rapid GPIO2P controller.

config LPC32XX_GPIO
	bool "LPC32XX GPIO driver"
	depends on DM
	default n
	help
	  Support for the LPC32XX GPIO driver.

config MSM_GPIO
	bool "Qualcomm GPIO driver"
	depends on DM_GPIO
	default n
	help
	  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 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.
	  Default name for GPIO bank is "pm8916".
	  Power and reset buttons are placed in "pm8916_key" bank and
          have gpio numbers 0 and 1 respectively.

config PCF8575_GPIO
	bool "PCF8575 I2C GPIO Expander driver"
	depends on DM_GPIO && DM_I2C
	help
	 Support for PCF8575 I2C 16-bit GPIO expander. Most of these
	 chips are from NXP and TI.

config ROCKCHIP_GPIO
	bool "Rockchip GPIO driver"
	depends on DM_GPIO
	help
	  Support GPIO access on Rockchip SoCs. The GPIOs are arranged into
	  a number of banks (different for each SoC type) each with 32 GPIOs.
	  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
	bool "Tegra20..210 GPIO driver"
	depends on DM_GPIO
	help
	  Support for the GPIO controller contained in NVIDIA Tegra20 through
	  Tegra210.

config TEGRA186_GPIO
	bool "Tegra186 GPIO driver"
	depends on DM_GPIO
	help
	  Support for the GPIO controller contained in NVIDIA Tegra186. This
	  covers both the "main" and "AON" controller instances, even though
	  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.

config PIC32_GPIO
	bool "Microchip PIC32 GPIO driver"
	depends on DM_GPIO && MACH_PIC32
	default y
	help
	  Say yes here to support Microchip PIC32 GPIOs.

	depends on DM_GPIO && ARCH_MVEBU
	default y
	help
	  Say yes here to support Marvell MVEBU (Armada XP/38x) GPIOs.

config ZYNQ_GPIO
	bool "Zynq GPIO driver"
	depends on DM_GPIO && (ARCH_ZYNQ || ARCH_ZYNQMP)
	default y
	help
	  Supports GPIO access on Zynq SoC.

config DM_74X164
	bool "74x164 serial-in/parallel-out 8-bits shift register"
	depends on DM_GPIO
	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

	  16 bits:	max7312, max7313, pca9535, pca9539, pca9555, pca9575,
			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.
