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