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 select GENERIC_PINCONF 24 select GPIOLIB 25 select GPIOLIB_IRQCHIP 26 27config PINCTRL_IPROC_GPIO 28 bool "Broadcom iProc GPIO (with PINCONF) driver" 29 depends on OF_GPIO && (ARCH_BCM_IPROC || COMPILE_TEST) 30 select GPIOLIB_IRQCHIP 31 select PINCONF 32 select GENERIC_PINCONF 33 default ARCH_BCM_IPROC 34 help 35 Say yes here to enable the Broadcom iProc GPIO driver. 36 37 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use 38 same GPIO Controller IP hence this driver could be used for all. 39 40 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU 41 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and 42 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are 43 supported by this driver. 44 45 The Broadcom NSP has two GPIO controllers including the ChipcommonA 46 GPIO, the ChipcommonB GPIO. Later controller is supported by this 47 driver. 48 49 The Broadcom NS2 has two GPIO controller including the CRMU GPIO, 50 the ChipcommonG GPIO. Both controllers are supported by this driver. 51 52 The Broadcom Stingray GPIO controllers are supported by this driver. 53 54 All above SoCs GPIO controllers support basic PINCONF functions such 55 as bias pull up, pull down, and drive strength configurations, when 56 these pins are muxed to GPIO. 57 58 It provides the framework where pins from the individual GPIO can be 59 individually muxed to GPIO function, through interaction with the 60 SoCs IOMUX controller. This features could be used only on SoCs which 61 support individual pin muxing. 62 63config PINCTRL_CYGNUS_MUX 64 bool "Broadcom Cygnus IOMUX driver" 65 depends on (ARCH_BCM_CYGNUS || COMPILE_TEST) 66 depends on OF 67 select PINMUX 68 select GENERIC_PINCONF 69 default ARCH_BCM_CYGNUS 70 help 71 Say yes here to enable the Broadcom Cygnus IOMUX driver. 72 73 The Broadcom Cygnus IOMUX driver supports group based IOMUX 74 configuration, with the exception that certain individual pins 75 can be overridden to GPIO function 76 77config PINCTRL_NSP_GPIO 78 bool "Broadcom NSP GPIO (with PINCONF) driver" 79 depends on OF_GPIO && (ARCH_BCM_NSP || COMPILE_TEST) 80 select GPIOLIB_IRQCHIP 81 select PINCONF 82 select GENERIC_PINCONF 83 default ARCH_BCM_NSP 84 help 85 Say yes here to enable the Broadcom NSP GPIO driver. 86 87 The Broadcom Northstar Plus SoC ChipcommonA GPIO controller is 88 supported by this driver. 89 90 The ChipcommonA GPIO controller 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 94config PINCTRL_NS2_MUX 95 bool "Broadcom Northstar2 pinmux driver" 96 depends on OF 97 depends on ARCH_BCM_IPROC || COMPILE_TEST 98 select PINMUX 99 select GENERIC_PINCONF 100 default ARM64 && ARCH_BCM_IPROC 101 help 102 Say yes here to enable the Broadcom NS2 MUX driver. 103 104 The Broadcom Northstar2 IOMUX driver supports group based IOMUX 105 configuration. 106 107config PINCTRL_NSP_MUX 108 bool "Broadcom NSP IOMUX driver" 109 depends on (ARCH_BCM_NSP || COMPILE_TEST) 110 depends on OF 111 select PINMUX 112 select GENERIC_PINCONF 113 default ARCH_BCM_NSP 114 help 115 Say yes here to enable the Broadcom NSP SOC IOMUX driver. 116 117 The Broadcom Northstar Plus IOMUX driver supports pin based IOMUX 118 configuration, with certain individual pins can be overridden 119 to GPIO function. 120
