However, BCM6338 and BCM634517 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 read20 and/or written, and the direction changed from input to output.21 BCM6318, BCM6328, BCM6358, BCM6362, BCM6368 and BCM63268 have 32-bit data22 and dirout registers, where GPIO state can be read and/or written, and the23 direction changed from input to output.24 25properties:26 compatible:27 enum:28 - brcm,bcm6318-gpio29 - brcm,bcm6328-gpio30 - brcm,bcm6358-gpio31 - brcm,bcm6362-gpio32 - brcm,bcm6368-gpio33 - brcm,bcm63268-gpio34 35 gpio-controller: true36 37 "#gpio-cells":38 const: 239 40 gpio-ranges:41 maxItems: 142 43 native-endian: true44 45 reg:46 maxItems: 247 48 reg-names:49 items:50 - const: dirout51 - const: dat52 53required:54 - compatible55 - reg56 - reg-names57 - gpio-controller58 - '#gpio-cells'59 60additionalProperties: false61 62examples:63 - |64 gpio@0 {65 compatible = "brcm,bcm63268-gpio";66 reg-names = "dirout", "dat";67 reg = <0x0 0x8>, <0x8 0x8>;68 69 gpio-controller;70 gpio-ranges = <&pinctrl 0 0 52>;71 #gpio-cells = <2>;72 };73
