# # Intel pin control drivers # config PINCTRL_BAYTRAIL bool "Intel Baytrail GPIO pin control" depends on GPIOLIB && ACPI select GPIOLIB_IRQCHIP help driver for memory mapped GPIO functionality on Intel Baytrail platforms. Supports 3 banks with 102, 28 and 44 gpios. Most pins are usually muxed to some other functionality by firmware, so only a small amount is available for gpio use. Requires ACPI device enumeration code to set up a platform device. config PINCTRL_CHERRYVIEW tristate "Intel Cherryview/Braswell pinctrl and GPIO driver" depends on ACPI select PINMUX select PINCONF select GENERIC_PINCONF select GPIOLIB select GPIOLIB_IRQCHIP help Cherryview/Braswell pinctrl driver provides an interface that allows configuring of SoC pins and using them as GPIOs.
