This driver requires the pinctrl framework. GPIO is provided by a separate GPIO driver. config PINCTRL_BCM2835 bool "Broadcom BCM2835 GPIO (with PINCONF) driver" depends on OF && (ARCH_BCM2835 || ARCH_BRCMSTB || COMPILE_TEST) select PINMUX select PINCONF select GENERIC_PINCONF select GPIOLIB_IRQCHIP default ARCH_BCM2835 || ARCH_BRCMSTB help Say Y here to enable the Broadcom BCM2835 GPIO driver. config PINCTRL_IPROC_GPIO bool "Broadcom iProc GPIO (with PINCONF) driver" depends on OF_GPIO && (ARCH_BCM_IPROC || COMPILE_TEST) select GPIOLIB_IRQCHIP select PINCONF select GENERIC_PINCONF default ARCH_BCM_IPROC help Say yes here to enable the Broadcom iProc GPIO driver. The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use same GPIO Controller IP hence this driver could be used for all. The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are supported by this driver. The Broadcom NSP has two GPIO controllers including the ChipcommonA GPIO, the ChipcommonB GPIO. Later controller is supported by this driver. The Broadcom NS2 has two GPIO controller including the CRMU GPIO, the ChipcommonG GPIO. Both controllers are supported by this driver. The Broadcom Stingray GPIO controllers are supported by this driver. All above SoCs GPIO controllers support basic PINCONF functions such as bias pull up, pull down, and drive strength configurations, when these pins are muxed to GPIO. It provides the framework where pins from the individual GPIO can be individually muxed to GPIO function, through interaction with the SoCs IOMUX controller. This features could be used only on SoCs which support individual pin muxing. config PINCTRL_CYGNUS_MUX bool "Broadcom Cygnus IOMUX driver" depends on (ARCH_BCM_CYGNUS || COMPILE_TEST) depends on OF select PINMUX select GENERIC_PINCONF default ARCH_BCM_CYGNUS help Say yes here to enable the Broadcom Cygnus IOMUX driver.
