All pins 15 may be used as GPIOs, multiplexed device functions are configured within the 16 GPIO port configuration registers and it is typical to refer to pins using the 17 naming scheme "PxN" where x is a character identifying the GPIO port with 18 which the pin is associated and N is an integer from 0 to 31 identifying the 19 pin within that GPIO port. For example PA0 is the first pin in GPIO port A, 20 and PB31 is the last pin in GPIO port B. The JZ4730, the JZ4740, the JZ4725B, 21 the X1000 and the X1830 contains 4 GPIO ports, PA to PD, for a total of 128 22 pins. The X2000 and the X2100 contains 5 GPIO ports, PA to PE, for a total of 23 160 pins. The JZ4750, the JZ4755 the JZ4760, the JZ4770 and the JZ4780 contains 24 6 GPIO ports, PA to PF, for a total of 192 pins. The JZ4775 contains 7 GPIO 25 ports, PA to PG, for a total of 224 pins. 26 27maintainers: 28 - Paul Cercueil <paul@crapouillou.net> 29 30properties: 31 compatible: 32 oneOf: 33 - enum: 34 - ingenic,jz4730-pinctrl 35 - ingenic,jz4740-pinctrl 36 - ingenic,jz4725b-pinctrl 37 - ingenic,jz4750-pinctrl 38 - ingenic,jz4755-pinctrl 39 - ingenic,jz4760-pinctrl 40 - ingenic,jz4770-pinctrl 41 - ingenic,jz4775-pinctrl 42 - ingenic,jz4780-pinctrl 43 - ingenic,x1000-pinctrl 44 - ingenic,x1500-pinctrl 45 - ingenic,x1830-pinctrl 46 - ingenic,x2000-pinctrl 47 - ingenic,x2100-pinctrl 48 - items: 49 - const: ingenic,jz4760b-pinctrl 50 - const: ingenic,jz4760-pinctrl 51 - items: 52 - const: ingenic,x1000e-pinctrl 53 - const: ingenic,x1000-pinctrl 54 - items: 55 - const: ingenic,x2000e-pinctrl 56 - const: ingenic,x2000-pinctrl 57 58 reg: 59 maxItems: 1 60 61 "#address-cells": 62 const: 1 63 64 "#size-cells": 65 const: 0 66 67patternProperties: 68 "^gpio@[0-9]$": 69 type: object 70 properties: 71 compatible: 72 enum: 73 - ingenic,jz4730-gpio 74 - ingenic,jz4740-gpio 75 - ingenic,jz4725b-gpio 76 - ingenic,jz4750-gpio 77 - ingenic,jz4755-gpio 78 - ingenic,jz4760-gpio 79 - ingenic,jz4770-gpio 80 - ingenic,jz4775-gpio 81 - ingenic,jz4780-gpio 82 - ingenic,x1000-gpio 83 - ingenic,x1500-gpio 84 - ingenic,x1830-gpio 85 - ingenic,x2000-gpio 86 - ingenic,x2100-gpio 87 88 reg: 89 items: 90 - description: The GPIO bank number 91 92 gpio-controller: true 93 94 "#gpio-cells": 95 const: 2 96 97 gpio-ranges: 98 maxItems: 1 99 100 interrupt-controller: true 101 102 "#interrupt-cells": 103 const: 2 104 description: 105 Refer to ../interrupt-controller/interrupts.txt for more details. 106 107 interrupts: 108 maxItems: 1 109 110 required: 111 - compatible 112 - reg 113 - gpio-controller 114 - "#gpio-cells" 115 - interrupts 116 - interrupt-controller 117 - "#interrupt-cells" 118 119 additionalProperties: false 120 121allOf: 122 - $ref: pinctrl.yaml# 123 124required: 125 - compatible 126 - reg 127 - "#address-cells" 128 - "#size-cells" 129 130additionalProperties: 131 anyOf: 132 - type: object 133 allOf: 134 - $ref: pincfg-node.yaml# 135 - $ref: pinmux-node.yaml# 136 137 properties: 138 phandle: true 139 function: true 140 groups: true 141 pins: true 142 bias-disable: true 143 bias-pull-up: true 144 bias-pull-down: true 145 output-low: true 146 output-high: true 147 additionalProperties: false 148 149 - type: object 150 properties: 151 phandle: true 152 additionalProperties: 153 type: object 154 allOf: 155 - $ref: pincfg-node.yaml# 156 - $ref: pinmux-node.yaml# 157 158 properties: 159 phandle: true 160 function: true 161 groups: true 162 pins: true 163 bias-disable: true 164 bias-pull-up: true 165 bias-pull-down: true 166 output-low: true 167 output-high: true 168 additionalProperties: false 169 170examples: 171 - | 172 pinctrl@10010000 { 173 compatible = "ingenic,jz4770-pinctrl"; 174 reg = <0x10010000 0x600>; 175 176 #address-cells = <1>; 177 #size-cells = <0>; 178 179 gpio@0 { 180 compatible = "ingenic,jz4770-gpio"; 181 reg = <0>; 182 183 gpio-controller; 184 gpio-ranges = <&pinctrl 0 0 32>; 185 #gpio-cells = <2>; 186 187 interrupt-controller; 188 #interrupt-cells = <2>; 189 190 interrupt-parent = <&intc>; 191 interrupts = <17>; 192 }; 193 }; 194
