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 function: true 139 groups: true 140 pins: true 141 bias-disable: true 142 bias-pull-up: true 143 bias-pull-down: true 144 output-low: true 145 output-high: true 146 additionalProperties: false 147 148 - type: object 149 additionalProperties: 150 type: object 151 allOf: 152 - $ref: pincfg-node.yaml# 153 - $ref: pinmux-node.yaml# 154 155 properties: 156 function: true 157 groups: true 158 pins: true 159 bias-disable: true 160 bias-pull-up: true 161 bias-pull-down: true 162 output-low: true 163 output-high: true 164 additionalProperties: false 165 166examples: 167 - | 168 pinctrl@10010000 { 169 compatible = "ingenic,jz4770-pinctrl"; 170 reg = <0x10010000 0x600>; 171 172 #address-cells = <1>; 173 #size-cells = <0>; 174 175 gpio@0 { 176 compatible = "ingenic,jz4770-gpio"; 177 reg = <0>; 178 179 gpio-controller; 180 gpio-ranges = <&pinctrl 0 0 32>; 181 #gpio-cells = <2>; 182 183 interrupt-controller; 184 #interrupt-cells = <2>; 185 186 interrupt-parent = <&intc>; 187 interrupts = <17>; 188 }; 189 }; 190
