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 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 SPL_PINCTRL
	bool "Support pin controlloers 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 SPL_PINCTRL_FULL
	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_FULL option.
	  See the help of PINCTRL_FULL for details.

config SPL_PINCTRL_GENERIC
	bool "Support generic pin controllers in SPL"
	depends on SPL_PINCTRL_FULL
	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"
	depends on SPL_PINCTRL_GENERIC
	help
	  This option is an SPL-variant of the PINCONF option.
	  See the help of PINCONF for details.

config PINCTRL_AR933X
	bool "QCA/Athores ar933x pin control driver"
	depends on DM && SOC_AR933X
	help
	  Support pin multiplexing control on QCA/Athores ar933x SoCs.
	  The driver is controlled by a device tree node which contains
	  both the GPIO definitions and pin control functions for each
	  available multiplex function.

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
	bool "AT91 PIO4 pinctrl driver"
	depends on DM
	help
	  This option is to enable the AT91 pinctrl driver for AT91 PIO4
	  controller which is available on SAMA5D2 SoC.

config PINCTRL_PIC32
	bool "Microchip PIC32 pin-control and pin-mux driver"
	depends on DM && MACH_PIC32
	default y
	help
	  Supports individual pin selection and configuration for each
	  remappable peripheral available on Microchip PIC32
	  SoCs. This driver is controlled by a device tree node which
	  contains both GPIO defintion and pin control functions.

config PINCTRL_QCA953X
	bool "QCA/Athores qca953x pin control driver"
	depends on DM && SOC_QCA953X
	help
	  Support pin multiplexing control on QCA/Athores qca953x SoCs.

	  The driver is controlled by a device tree node which contains both
	  the GPIO definitions and pin control functions for each available
	  multiplex function.

config PINCTRL_ROCKCHIP_RK3036
	bool "Rockchip rk3036 pin control driver"
	depends on DM
	help
	  Support pin multiplexing control on Rockchip rk3036 SoCs.

	  The driver is controlled by a device tree node which contains both
	  the GPIO definitions and pin control functions for each available
	  multiplex function.

config PINCTRL_ROCKCHIP_RK3188
	bool "Rockchip rk3188 pin control driver"
	depends on DM
	help
	  Support pin multiplexing control on Rockchip rk3188 SoCs.

	  The driver is controlled by a device tree node which contains both
	  the GPIO definitions and pin control functions for each available
	  multiplex function.

config PINCTRL_ROCKCHIP_RK3288
	bool "Rockchip rk3288 pin control driver"
	depends on DM
	help
	  Support pin multiplexing control on Rockchip rk3288 SoCs.

	  The driver is controlled by a device tree node which contains both
	  the GPIO definitions and pin control functions for each available
	  multiplex function.

config PINCTRL_ROCKCHIP_RK3328

	depends on DM
	help
	  Support pin multiplexing control on Rockchip rk3328 SoCs.

	  The driver is controlled by a device tree node which contains both
	  the GPIO definitions and pin control functions for each available
	  multiplex function.

config PINCTRL_ROCKCHIP_RK3399
	bool "Rockchip rk3399 pin control driver"
	depends on DM
	help
	  Support pin multiplexing control on Rockchip rk3399 SoCs.

	  The driver is controlled by a device tree node which contains both
	  the GPIO definitions and pin control functions for each available
	  multiplex function.

config PINCTRL_SANDBOX
	bool "Sandbox pinctrl driver"
	depends on SANDBOX
	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.

config PINCTRL_STI
	bool "STMicroelectronics STi pin-control and pin-mux driver"
	depends on DM && ARCH_STI
	default y
	help
	  Support pin multiplexing control on STMicrolectronics STi SoCs.

	Generic Pinctrl framework and is compatible with the Linux driver,
	i.e. it uses the same device tree configuration.
