config ARCH_HAVE_CUSTOM_GPIO_H
	bool
	help
	  Selecting this config option from the architecture Kconfig allows
	  the architecture to provide a custom asm/gpio.h implementation
	  overriding the default implementations.  New uses of this are
	  strongly discouraged.

config ARCH_WANT_OPTIONAL_GPIOLIB
	bool
	help
	  Select this config option from the architecture Kconfig, if
	  it is possible to use gpiolib on the architecture, but let the
	  user decide whether to actually build it or not.
	  Select this instead of ARCH_REQUIRE_GPIOLIB, if your architecture does
	  not depend on GPIOs being available, but rather let the user
	  decide whether he needs it or not.

config ARCH_REQUIRE_GPIOLIB
	bool
	select GPIOLIB
	help
	  Platforms select gpiolib if they use this infrastructure
	  for all their GPIOs, usually starting with ones integrated
	  into SOC processors.
	  Selecting this from the architecture code will cause the gpiolib
	  code to always get built in.


menuconfig GPIOLIB
	bool "GPIO Support"
	depends on ARCH_WANT_OPTIONAL_GPIOLIB || ARCH_REQUIRE_GPIOLIB
	select GENERIC_GPIO
	help
	  This enables GPIO support through the generic GPIO library.
	  You only need to enable this, if you also want to enable
	  one or more of the GPIO drivers below.

config OF_GPIO

config DEBUG_GPIO
	bool "Debug GPIO calls"
	depends on DEBUG_KERNEL
	help
	  Say Y here to add some extra checks and diagnostics to GPIO calls.
	  These checks help ensure that GPIOs have been properly initialized
	  before they are used, and that sleeping calls are not made from
	  non-sleeping contexts.  They can make bitbanged serial protocols
	  slower.  The diagnostics help catch the type of setup errors
	  that are most common when setting up new platforms or boards.

config GPIO_SYSFS
	bool "/sys/class/gpio/... (sysfs interface)"
	depends on SYSFS && EXPERIMENTAL
	help
	  Say Y here to add a sysfs interface for GPIOs.

	  This is mostly useful to work around omissions in a system's
	  kernel support.  Those are common in custom and semicustom
	  hardware assembled using standard kernels with a minimum of
	  custom patches.  In those cases, userspace code may import
	  a given GPIO from the kernel, if no kernel driver requested it.

	  Kernel drivers may also request that a particular GPIO be
	  exported to userspace; this can be useful when debugging.

	  the Intel SCH suspend power supply. These GPIOs remain
	  active during S3. The suspend powered GPIOs can be used to wake the
	  system from the Suspend-to-RAM state.
	  The Intel Tunnel Creek processor has 5 GPIOs powered by the
	  core power rail and 9 from suspend power supply.

config GPIO_VX855

	  Input and Output (designed by 'P'). The combinations are listed
	  below:

	  8 bits:	max7319 (8I), max7320 (8O), max7321 (8P),
		  	max7322 (4I4O), max7323 (4P4O)

	  16 bits:	max7324 (8I8O), max7325 (8P8O),
		  	max7326 (4I12O), max7327 (4P12O)

	  Board setup code must specify the model to use, and the start
	  number for these GPIOs.

config GPIO_MAX732X_IRQ
	bool "Interrupt controller support for MAX732x"
	depends on GPIO_MAX732X=y && GENERIC_HARDIRQS
	help
	  Say yes here to enable the max732x to be used as an interrupt

	            pca9671, pca9673, pca9675

	  Your board setup code will need to declare the expanders in
	  use, and assign numbers to the GPIOs they expose.  Those GPIOs
	  can then be used from drivers and other kernel code, just like
	  other GPIOs, but only accessible from task contexts.

	  This driver provides an in-kernel interface to those GPIOs using
	  platform-neutral GPIO calls.
