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_IPROC_GPIO 56 bool "Broadcom iProc GPIO (with PINCONF) driver" 57 depends on OF_GPIO && (ARCH_BCM_IPROC || COMPILE_TEST) 58 select GPIOLIB_IRQCHIP 59 select PINCONF 60 select GENERIC_PINCONF 61 default ARCH_BCM_IPROC 62 help 63 Say yes here to enable the Broadcom iProc GPIO driver. 64 65 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use 66 same GPIO Controller IP hence this driver could be used for all. 67 68 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU 69 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and 70 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are 71 supported by this driver. 72 73 The Broadcom NSP has two GPIO controllers including the ChipcommonA 74 GPIO, the ChipcommonB GPIO. Later controller is supported by this 75 driver. 76 77 The Broadcom NS2 has two GPIO controller including the CRMU GPIO, 78 the ChipcommonG GPIO. Both controllers are supported by this driver. 79 80 The Broadcom Stingray GPIO controllers are supported by this driver. 81 82 All above SoCs GPIO controllers support basic PINCONF functions such 83 as bias pull up, pull down, and drive strength configurations, when 84 these pins are muxed to GPIO. 85 86 It provides the framework where pins from the individual GPIO can be 87 individually muxed to GPIO function, through interaction with the 88 SoCs IOMUX controller. This features could be used only on SoCs which 89 support individual pin muxing. 90 91config PINCTRL_CYGNUS_MUX 92 bool "Broadcom Cygnus IOMUX driver" 93 depends on (ARCH_BCM_CYGNUS || COMPILE_TEST) 94 depends on OF 95 select PINMUX 96 select GENERIC_PINCONF 97 default ARCH_BCM_CYGNUS 98 help 99 Say yes here to enable the Broadcom Cygnus IOMUX driver. 100 101 The Broadcom Cygnus IOMUX driver supports group based IOMUX 102 configuration, with the exception that certain individual pins 103 can be overridden to GPIO function 104 105config PINCTRL_NS 106 bool "Broadcom Northstar pins driver" 107 depends on OF && (ARCH_BCM_5301X || COMPILE_TEST) 108 select PINMUX 109 select GENERIC_PINCONF 110 default ARCH_BCM_5301X 111 help 112 Say yes here to enable the Broadcom NS SoC pins driver. 113 114 The Broadcom Northstar pins driver supports muxing multi-purpose pins 115 that can be used for various functions (e.g. SPI, I2C, UART) as well 116 as GPIOs. 117 118config PINCTRL_NSP_GPIO 119 bool "Broadcom NSP GPIO (with PINCONF) driver" 120 depends on OF_GPIO && (ARCH_BCM_NSP || COMPILE_TEST) 121 select GPIOLIB_IRQCHIP 122 select PINCONF 123 select GENERIC_PINCONF 124 default ARCH_BCM_NSP 125 help 126 Say yes here to enable the Broadcom NSP GPIO driver. 127 128 The Broadcom Northstar Plus SoC ChipcommonA GPIO controller is 129 supported by this driver. 130 131 The ChipcommonA GPIO controller support basic PINCONF functions such 132 as bias pull up, pull down, and drive strength configurations, when 133 these pins are muxed to GPIO. 134 135config PINCTRL_NS2_MUX 136 bool "Broadcom Northstar2 pinmux driver" 137 depends on OF 138 depends on ARCH_BCM_IPROC || COMPILE_TEST 139 select PINMUX 140 select GENERIC_PINCONF 141 default ARM64 && ARCH_BCM_IPROC 142 help 143 Say yes here to enable the Broadcom NS2 MUX driver. 144 145 The Broadcom Northstar2 IOMUX driver supports group based IOMUX 146 configuration. 147 148config PINCTRL_NSP_MUX 149 bool "Broadcom NSP IOMUX driver" 150 depends on (ARCH_BCM_NSP || COMPILE_TEST) 151 depends on OF 152 select PINMUX 153 select GENERIC_PINCONF 154 default ARCH_BCM_NSP 155 help 156 Say yes here to enable the Broadcom NSP SOC IOMUX driver. 157 158 The Broadcom Northstar Plus IOMUX driver supports pin based IOMUX 159 configuration, with certain individual pins can be overridden 160 to GPIO function. 161
