This driver requires the pinctrl 16b17f2f9bSRay Jui framework. GPIO is provided by a separate GPIO driver. 17b17f2f9bSRay Jui 18b17f2f9bSRay Juiconfig PINCTRL_BCM2835 19b17f2f9bSRay Jui bool 20b17f2f9bSRay Jui select PINMUX 21b17f2f9bSRay Jui select PINCONF 22cbd159edSRay Jui 23*616043d5SPramod Kumarconfig PINCTRL_IPROC_GPIO 24*616043d5SPramod Kumar bool "Broadcom iProc GPIO (with PINCONF) driver" 25*616043d5SPramod Kumar depends on OF_GPIO && (ARCH_BCM_IPROC || COMPILE_TEST) 26b64333ceSRay Jui select GPIOLIB_IRQCHIP 27b64333ceSRay Jui select PINCONF 28b64333ceSRay Jui select GENERIC_PINCONF 29*616043d5SPramod Kumar default ARCH_BCM_IPROC 30b64333ceSRay Jui help 31*616043d5SPramod Kumar Say yes here to enable the Broadcom iProc GPIO driver. 32*616043d5SPramod Kumar 33*616043d5SPramod Kumar The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use 34*616043d5SPramod Kumar same GPIO Controller IP hence this driver could be used for all. 35b64333ceSRay Jui 36b64333ceSRay Jui The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU 37b64333ceSRay Jui GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and 38b64333ceSRay Jui the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are 39b64333ceSRay Jui supported by this driver. 40b64333ceSRay Jui 41*616043d5SPramod Kumar The Broadcom NSP has two GPIO controllers including the ChipcommonA 42*616043d5SPramod Kumar GPIO, the ChipcommonB GPIO. Later controller is supported by this 43*616043d5SPramod Kumar driver. 44*616043d5SPramod Kumar 45*616043d5SPramod Kumar The Broadcom NS2 has two GPIO controller including the CRMU GPIO, 46*616043d5SPramod Kumar the ChipcommonG GPIO. Both controllers are supported by this driver. 47*616043d5SPramod Kumar 48*616043d5SPramod Kumar The Broadcom Stingray GPIO controllers are supported by this driver. 49*616043d5SPramod Kumar 50*616043d5SPramod Kumar All above SoCs GPIO controllers support basic PINCONF functions such 51b64333ceSRay Jui as bias pull up, pull down, and drive strength configurations, when 52b64333ceSRay Jui these pins are muxed to GPIO. 53b64333ceSRay Jui 54*616043d5SPramod Kumar It provides the framework where pins from the individual GPIO can be 55*616043d5SPramod Kumar individually muxed to GPIO function, through interaction with the 56*616043d5SPramod Kumar SoCs IOMUX controller. This features could be used only on SoCs which 57*616043d5SPramod Kumar support individual pin muxing. 58b64333ceSRay Jui 59cbd159edSRay Juiconfig PINCTRL_CYGNUS_MUX 60cbd159edSRay Jui bool "Broadcom Cygnus IOMUX driver" 61cbd159edSRay Jui depends on (ARCH_BCM_CYGNUS || COMPILE_TEST) 62cbd159edSRay Jui select PINMUX 63cbd159edSRay Jui select GENERIC_PINCONF 64cbd159edSRay Jui default ARCH_BCM_CYGNUS 65cbd159edSRay Jui help 66cbd159edSRay Jui Say yes here to enable the Broadcom Cygnus IOMUX driver. 67cbd159edSRay Jui 68cbd159edSRay Jui The Broadcom Cygnus IOMUX driver supports group based IOMUX 69cbd159edSRay Jui configuration, with the exception that certain individual pins 70cbd159edSRay Jui can be overrided to GPIO function 71
