# # GPIO infrastructure and drivers # 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. menuconfig GPIOLIB bool "GPIO Support" 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. If unsure, say N. if GPIOLIB config GPIOLIB_FASTPATH_LIMIT int "Maximum number of GPIOs for fast path" range 32 512 default 512 help This adjusts the point at which certain APIs will switch from using a stack allocated buffer to a dynamically allocated buffer. You shouldn't need to change this unless you really need to optimize either stack space or performance. Change this carefully since setting an incorrect value could cause stack corruption. config OF_GPIO def_bool y depends on OF depends on HAS_IOMEM config GPIO_ACPI def_bool y depends on ACPI config GPIOLIB_IRQCHIP select IRQ_DOMAIN bool 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.

Kernel drivers may also request that a particular GPIO be exported to userspace; this can be useful when debugging. config GPIO_GENERIC depends on HAS_IOMEM # Only for IOMEM drivers tristate # put drivers in the right section, in alphabetical order # This symbol is selected by both I2C and SPI expanders config GPIO_MAX730X tristate menu "Memory mapped GPIO drivers" depends on HAS_IOMEM config GPIO_74XX_MMIO tristate "GPIO driver for 74xx-ICs with MMIO access" depends on OF_GPIO select GPIO_GENERIC help Say yes here to support GPIO functionality for 74xx-compatible ICs with MMIO access.
