This driver requires the pinctrl 18 framework. GPIO is provided by a separate GPIO driver. 19 20config PINCTRL_BCM2835 21 bool "Broadcom BCM2835 GPIO (with PINCONF) driver" 22 depends on OF && (ARCH_BCM2835 || ARCH_BRCMSTB || COMPILE_TEST) 23 select PINMUX 24 select PINCONF 25 select GENERIC_PINCONF 26 select GPIOLIB 27 select GPIOLIB_IRQCHIP 28 default ARCH_BCM2835 || ARCH_BRCMSTB 29 help 30 Say Y here to enable the Broadcom BCM2835 GPIO driver. 31 32config PINCTRL_BCM63XX 33 bool 34 select GENERIC_PINCONF 35 select GPIO_REGMAP 36 select PINCONF 37 select PINMUX 38 39config PINCTRL_BCM6328 40 bool "Broadcom BCM6328 GPIO driver" 41 depends on (BMIPS_GENERIC || COMPILE_TEST) 42 select PINCTRL_BCM63XX 43 default BMIPS_GENERIC 44 help 45 Say Y here to enable the Broadcom BCM6328 GPIO driver. 46 47config PINCTRL_BCM6358 48 bool "Broadcom BCM6358 GPIO driver" 49 depends on (BMIPS_GENERIC || COMPILE_TEST) 50 select PINCTRL_BCM63XX 51 default BMIPS_GENERIC 52 help 53 Say Y here to enable the Broadcom BCM6358 GPIO driver. 54 55config PINCTRL_BCM6362 56 bool "Broadcom BCM6362 GPIO driver" 57 depends on (BMIPS_GENERIC || COMPILE_TEST) 58 select PINCTRL_BCM63XX 59 default BMIPS_GENERIC 60 help 61 Say Y here to enable the Broadcom BCM6362 GPIO driver. 62 63config PINCTRL_IPROC_GPIO 64 bool "Broadcom iProc GPIO (with PINCONF) driver" 65 depends on OF_GPIO && (ARCH_BCM_IPROC || COMPILE_TEST) 66 select GPIOLIB_IRQCHIP 67 select PINCONF 68 select GENERIC_PINCONF 69 default ARCH_BCM_IPROC 70 help 71 Say yes here to enable the Broadcom iProc GPIO driver. 72 73 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use 74 same GPIO Controller IP hence this driver could be used for all. 75 76 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU 77 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and 78 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are 79 supported by this driver. 80 81 The Broadcom NSP has two GPIO controllers including the ChipcommonA 82 GPIO, the ChipcommonB GPIO. Later controller is supported by this 83 driver. 84 85 The Broadcom NS2 has two GPIO controller including the CRMU GPIO, 86 the ChipcommonG GPIO. Both controllers are supported by this driver. 87 88 The Broadcom Stingray GPIO controllers are supported by this driver. 89 90 All above SoCs GPIO controllers support basic PINCONF functions such 91 as bias pull up, pull down, and drive strength configurations, when 92 these pins are muxed to GPIO. 93 94 It provides the framework where pins from the individual GPIO can be 95 individually muxed to GPIO function, through interaction with the 96 SoCs IOMUX controller.
