This driver requires the pinctrl 17 framework. GPIO is provided by a separate GPIO driver. 18 19config PINCTRL_BCM2835 20 bool 21 select PINMUX 22 select PINCONF 23 24config PINCTRL_IPROC_GPIO 25 bool "Broadcom iProc GPIO (with PINCONF) driver" 26 depends on OF_GPIO && (ARCH_BCM_IPROC || COMPILE_TEST) 27 select GPIOLIB_IRQCHIP 28 select PINCONF 29 select GENERIC_PINCONF 30 default ARCH_BCM_IPROC 31 help 32 Say yes here to enable the Broadcom iProc GPIO driver. 33 34 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use 35 same GPIO Controller IP hence this driver could be used for all. 36 37 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU 38 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and 39 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are 40 supported by this driver. 41 42 The Broadcom NSP has two GPIO controllers including the ChipcommonA 43 GPIO, the ChipcommonB GPIO. Later controller is supported by this 44 driver. 45 46 The Broadcom NS2 has two GPIO controller including the CRMU GPIO, 47 the ChipcommonG GPIO. Both controllers are supported by this driver. 48 49 The Broadcom Stingray GPIO controllers are supported by this driver. 50 51 All above SoCs GPIO controllers support basic PINCONF functions such 52 as bias pull up, pull down, and drive strength configurations, when 53 these pins are muxed to GPIO. 54 55 It provides the framework where pins from the individual GPIO can be 56 individually muxed to GPIO function, through interaction with the 57 SoCs IOMUX controller. This features could be used only on SoCs which 58 support individual pin muxing. 59 60config PINCTRL_CYGNUS_MUX 61 bool "Broadcom Cygnus IOMUX driver" 62 depends on (ARCH_BCM_CYGNUS || COMPILE_TEST) 63 select PINMUX 64 select GENERIC_PINCONF 65 default ARCH_BCM_CYGNUS 66 help 67 Say yes here to enable the Broadcom Cygnus IOMUX driver. 68 69 The Broadcom Cygnus IOMUX driver supports group based IOMUX 70 configuration, with the exception that certain individual pins 71 can be overrided to GPIO function 72 73config PINCTRL_NSP_GPIO 74 bool "Broadcom NSP GPIO (with PINCONF) driver" 75 depends on OF_GPIO && (ARCH_BCM_NSP || COMPILE_TEST) 76 select GPIOLIB_IRQCHIP 77 select PINCONF 78 select GENERIC_PINCONF 79 default ARCH_BCM_NSP 80 help 81 Say yes here to enable the Broadcom NSP GPIO driver. 82 83 The Broadcom Northstar Plus SoC ChipcommonA GPIO controller is 84 supported by this driver. 85 86 The ChipcommonA GPIO controller support basic PINCONF functions such 87 as bias pull up, pull down, and drive strength configurations, when 88 these pins are muxed to GPIO. 89
