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 GPIOLIB_IRQCHIP 24 25config PINCTRL_IPROC_GPIO 26 bool "Broadcom iProc GPIO (with PINCONF) driver" 27 depends on OF_GPIO && (ARCH_BCM_IPROC || COMPILE_TEST) 28 select GPIOLIB_IRQCHIP 29 select PINCONF 30 select GENERIC_PINCONF 31 default ARCH_BCM_IPROC 32 help 33 Say yes here to enable the Broadcom iProc GPIO driver. 34 35 The Broadcom iProc based SoCs- Cygnus, NS2, NSP and Stingray, use 36 same GPIO Controller IP hence this driver could be used for all. 37 38 The Broadcom Cygnus SoC has 3 GPIO controllers including the ASIU 39 GPIO controller (ASIU), the chipCommonG GPIO controller (CCM), and 40 the always-ON GPIO controller (CRMU/AON). All 3 GPIO controllers are 41 supported by this driver. 42 43 The Broadcom NSP has two GPIO controllers including the ChipcommonA 44 GPIO, the ChipcommonB GPIO. Later controller is supported by this 45 driver. 46 47 The Broadcom NS2 has two GPIO controller including the CRMU GPIO, 48 the ChipcommonG GPIO. Both controllers are supported by this driver. 49 50 The Broadcom Stingray GPIO controllers are supported by this driver. 51 52 All above SoCs GPIO controllers support basic PINCONF functions such 53 as bias pull up, pull down, and drive strength configurations, when 54 these pins are muxed to GPIO. 55 56 It provides the framework where pins from the individual GPIO can be 57 individually muxed to GPIO function, through interaction with the 58 SoCs IOMUX controller. This features could be used only on SoCs which 59 support individual pin muxing. 60 61config PINCTRL_CYGNUS_MUX 62 bool "Broadcom Cygnus IOMUX driver" 63 depends on (ARCH_BCM_CYGNUS || COMPILE_TEST) 64 depends on OF 65 select PINMUX 66 select GENERIC_PINCONF 67 default ARCH_BCM_CYGNUS 68 help 69 Say yes here to enable the Broadcom Cygnus IOMUX driver. 70 71 The Broadcom Cygnus IOMUX driver supports group based IOMUX 72 configuration, with the exception that certain individual pins 73 can be overridden to GPIO function 74 75config PINCTRL_NSP_GPIO 76 bool "Broadcom NSP GPIO (with PINCONF) driver" 77 depends on OF_GPIO && (ARCH_BCM_NSP || COMPILE_TEST) 78 select GPIOLIB_IRQCHIP 79 select PINCONF 80 select GENERIC_PINCONF 81 default ARCH_BCM_NSP 82 help 83 Say yes here to enable the Broadcom NSP GPIO driver. 84 85 The Broadcom Northstar Plus SoC ChipcommonA GPIO controller is 86 supported by this driver. 87 88 The ChipcommonA GPIO controller support basic PINCONF functions such 89 as bias pull up, pull down, and drive strength configurations, when 90 these pins are muxed to GPIO. 91 92config PINCTRL_NS2_MUX 93 bool "Broadcom Northstar2 pinmux driver" 94 depends on OF 95 depends on ARCH_BCM_IPROC || COMPILE_TEST 96 select PINMUX 97 select GENERIC_PINCONF 98 default ARM64 && ARCH_BCM_IPROC 99 help 100 Say yes here to enable the Broadcom NS2 MUX driver. 101 102 The Broadcom Northstar2 IOMUX driver supports group based IOMUX 103 configuration. 104 105config PINCTRL_NSP_MUX 106 bool "Broadcom NSP IOMUX driver" 107 depends on (ARCH_BCM_NSP || COMPILE_TEST) 108 depends on OF 109 select PINMUX 110 select GENERIC_PINCONF 111 default ARCH_BCM_NSP 112 help 113 Say yes here to enable the Broadcom NSP SOC IOMUX driver. 114 115 The Broadcom Northstar Plus IOMUX driver supports pin based IOMUX 116 configuration, with certain individual pins can be overridden 117 to GPIO function. 118
