However, BCM6338 and BCM6345 17 are the only ones which don't need a pinctrl driver. 18 19 BCM6338 have 8-bit data and dirout registers, where GPIO state can be read 20 and/or written, and the direction changed from input to output. 21 BCM6345 have 16-bit data and dirout registers, where GPIO state can be read 22 and/or written, and the direction changed from input to output. 23 BCM6318, BCM6328, BCM6358, BCM6362, BCM6368 and BCM63268 have 32-bit data 24 and dirout registers, where GPIO state can be read and/or written, and the 25 direction changed from input to output. 26 27properties: 28 compatible: 29 enum: 30 - brcm,bcm6318-gpio 31 - brcm,bcm6328-gpio 32 - brcm,bcm6345-gpio 33 - brcm,bcm6358-gpio 34 - brcm,bcm6362-gpio 35 - brcm,bcm6368-gpio 36 - brcm,bcm63268-gpio 37 38 gpio-controller: true 39 40 "#gpio-cells": 41 const: 2 42 43 gpio-ranges: 44 maxItems: 1 45 46 native-endian: true 47 48 reg: 49 maxItems: 2 50 51 reg-names: 52 items: 53 - const: dirout 54 - const: dat 55 56required: 57 - compatible 58 - reg 59 - reg-names 60 - gpio-controller 61 - '#gpio-cells' 62 63additionalProperties: false 64 65examples: 66 - | 67 gpio@fffe0406 { 68 compatible = "brcm,bcm6345-gpio"; 69 reg-names = "dirout", "dat"; 70 reg = <0xfffe0406 2>, <0xfffe040a 2>; 71 native-endian; 72 73 gpio-controller; 74 #gpio-cells = <2>; 75 }; 76 77 - | 78 gpio@0 { 79 compatible = "brcm,bcm63268-gpio"; 80 reg-names = "dirout", "dat"; 81 reg = <0x0 0x8>, <0x8 0x8>; 82 83 gpio-controller; 84 gpio-ranges = <&pinctrl 0 0 52>; 85 #gpio-cells = <2>; 86 }; 87
