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_IPROC_GPIO 48 bool "Broadcom iProc GPIO (with PINCONF) driver" 49 depends on OF_GPIO && (ARCH_BCM_IPROC || COMPILE_TEST) 50 select GPIOLIB_IRQCHIP 51 select PINCONF 52 select GENERIC_PINCONF 53 default ARCH_BCM_IPROC 54 help 55 Say yes here to enable the Broadcom iProc GPIO driver. 56 57 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use 58 same GPIO Controller IP hence this driver could be used for all. 59 60 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU 61 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and 62 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are 63 supported by this driver. 64 65 The Broadcom NSP has two GPIO controllers including the ChipcommonA 66 GPIO, the ChipcommonB GPIO. Later controller is supported by this 67 driver. 68 69 The Broadcom NS2 has two GPIO controller including the CRMU GPIO, 70 the ChipcommonG GPIO. Both controllers are supported by this driver. 71 72 The Broadcom Stingray GPIO controllers are supported by this driver. 73 74 All above SoCs GPIO controllers support basic PINCONF functions such 75 as bias pull up, pull down, and drive strength configurations, when 76 these pins are muxed to GPIO. 77 78 It provides the framework where pins from the individual GPIO can be 79 individually muxed to GPIO function, through interaction with the 80 SoCs IOMUX controller. This features could be used only on SoCs which 81 support individual pin muxing. 82 83config PINCTRL_CYGNUS_MUX 84 bool "Broadcom Cygnus IOMUX driver" 85 depends on (ARCH_BCM_CYGNUS || COMPILE_TEST) 86 depends on OF 87 select PINMUX 88 select GENERIC_PINCONF 89 default ARCH_BCM_CYGNUS 90 help 91 Say yes here to enable the Broadcom Cygnus IOMUX driver. 92 93 The Broadcom Cygnus IOMUX driver supports group based IOMUX 94 configuration, with the exception that certain individual pins 95 can be overridden to GPIO function 96 97config PINCTRL_NS 98 bool "Broadcom Northstar pins driver" 99 depends on OF && (ARCH_BCM_5301X || COMPILE_TEST) 100 select PINMUX 101 select GENERIC_PINCONF 102 default ARCH_BCM_5301X 103 help 104 Say yes here to enable the Broadcom NS SoC pins driver. 105 106 The Broadcom Northstar pins driver supports muxing multi-purpose pins 107 that can be used for various functions (e.g. SPI, I2C, UART) as well 108 as GPIOs. 109 110config PINCTRL_NSP_GPIO 111 bool "Broadcom NSP GPIO (with PINCONF) driver" 112 depends on OF_GPIO && (ARCH_BCM_NSP || COMPILE_TEST) 113 select GPIOLIB_IRQCHIP 114 select PINCONF 115 select GENERIC_PINCONF 116 default ARCH_BCM_NSP 117 help 118 Say yes here to enable the Broadcom NSP GPIO driver. 119 120 The Broadcom Northstar Plus SoC ChipcommonA GPIO controller is 121 supported by this driver. 122 123 The ChipcommonA GPIO controller support basic PINCONF functions such 124 as bias pull up, pull down, and drive strength configurations, when 125 these pins are muxed to GPIO. 126 127config PINCTRL_NS2_MUX 128 bool "Broadcom Northstar2 pinmux driver" 129 depends on OF 130 depends on ARCH_BCM_IPROC || COMPILE_TEST 131 select PINMUX 132 select GENERIC_PINCONF 133 default ARM64 && ARCH_BCM_IPROC 134 help 135 Say yes here to enable the Broadcom NS2 MUX driver. 136 137 The Broadcom Northstar2 IOMUX driver supports group based IOMUX 138 configuration. 139 140config PINCTRL_NSP_MUX 141 bool "Broadcom NSP IOMUX driver" 142 depends on (ARCH_BCM_NSP || COMPILE_TEST) 143 depends on OF 144 select PINMUX 145 select GENERIC_PINCONF 146 default ARCH_BCM_NSP 147 help 148 Say yes here to enable the Broadcom NSP SOC IOMUX driver. 149 150 The Broadcom Northstar Plus IOMUX driver supports pin based IOMUX 151 configuration, with certain individual pins can be overridden 152 to GPIO function. 153
