This driver requires the pinctrl 16 framework. GPIO is provided by a separate GPIO driver. 17 18config PINCTRL_BCM2835 19 bool 20 select PINMUX 21 select PINCONF 22 23config PINCTRL_CYGNUS_GPIO 24 bool "Broadcom Cygnus GPIO (with PINCONF) driver" 25 depends on OF_GPIO && ARCH_BCM_CYGNUS 26 select GPIOLIB_IRQCHIP 27 select PINCONF 28 select GENERIC_PINCONF 29 default ARCH_BCM_CYGNUS 30 help 31 Say yes here to enable the Broadcom Cygnus GPIO driver. 32 33 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU 34 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and 35 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are 36 supported by this driver. 37 38 All 3 Cygnus GPIO controllers support basic PINCONF functions such 39 as bias pull up, pull down, and drive strength configurations, when 40 these pins are muxed to GPIO. 41 42 Pins from the ASIU GPIO can be individually muxed to GPIO function, 43 through interaction with the Cygnus IOMUX controller. 44 45config PINCTRL_CYGNUS_MUX 46 bool "Broadcom Cygnus IOMUX driver" 47 depends on (ARCH_BCM_CYGNUS || COMPILE_TEST) 48 select PINMUX 49 select GENERIC_PINCONF 50 default ARCH_BCM_CYGNUS 51 help 52 Say yes here to enable the Broadcom Cygnus IOMUX driver. 53 54 The Broadcom Cygnus IOMUX driver supports group based IOMUX 55 configuration, with the exception that certain individual pins 56 can be overrided to GPIO function 57
