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*b64333ceSRay Juiconfig PINCTRL_CYGNUS_GPIO 24*b64333ceSRay Jui bool "Broadcom Cygnus GPIO (with PINCONF) driver" 25*b64333ceSRay Jui depends on OF_GPIO && ARCH_BCM_CYGNUS 26*b64333ceSRay Jui select GPIOLIB_IRQCHIP 27*b64333ceSRay Jui select PINCONF 28*b64333ceSRay Jui select GENERIC_PINCONF 29*b64333ceSRay Jui default ARCH_BCM_CYGNUS 30*b64333ceSRay Jui help 31*b64333ceSRay Jui Say yes here to enable the Broadcom Cygnus GPIO driver. 32*b64333ceSRay Jui 33*b64333ceSRay Jui The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU 34*b64333ceSRay Jui GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and 35*b64333ceSRay Jui the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are 36*b64333ceSRay Jui supported by this driver. 37*b64333ceSRay Jui 38*b64333ceSRay Jui All 3 Cygnus GPIO controllers support basic PINCONF functions such 39*b64333ceSRay Jui as bias pull up, pull down, and drive strength configurations, when 40*b64333ceSRay Jui these pins are muxed to GPIO. 41*b64333ceSRay Jui 42*b64333ceSRay Jui Pins from the ASIU GPIO can be individually muxed to GPIO function, 43*b64333ceSRay Jui through interaction with the Cygnus IOMUX controller. 44*b64333ceSRay Jui 45cbd159edSRay Juiconfig PINCTRL_CYGNUS_MUX 46cbd159edSRay Jui bool "Broadcom Cygnus IOMUX driver" 47cbd159edSRay Jui depends on (ARCH_BCM_CYGNUS || COMPILE_TEST) 48cbd159edSRay Jui select PINMUX 49cbd159edSRay Jui select GENERIC_PINCONF 50cbd159edSRay Jui default ARCH_BCM_CYGNUS 51cbd159edSRay Jui help 52cbd159edSRay Jui Say yes here to enable the Broadcom Cygnus IOMUX driver. 53cbd159edSRay Jui 54cbd159edSRay Jui The Broadcom Cygnus IOMUX driver supports group based IOMUX 55cbd159edSRay Jui configuration, with the exception that certain individual pins 56cbd159edSRay Jui can be overrided to GPIO function 57
