Vendor: Nuvoton Technology Corporation

Description

Nuvoton NCT38XX series I2C-based GPIO expander

This must be a child of the NCT38xx multi-function device.

Example:
  &i2c0_0 {
    nct3807@70 {
      compatible = "nuvoton,nct38xx";
      reg = <0x70>;

      nct3807-gpio {
        #address-cells = <1>;
        #size-cells = <0>;
        compatible = "nuvoton,nct38xx-gpio";

        gpio@0 {
          compatible = "nuvoton,nct38xx-gpio-port";
          reg = <0x0>;
          gpio-controller;
          #gpio-cells = <2>;
          ngpios = <8>;
          pin_mask = <0xff>;
          pinmux_mask = <0xf7>;
        };

        gpio@1 {
          compatible = "nuvoton,nct38xx-gpio-port";
          reg = <0x1>;
          gpio-controller;
          #gpio-cells = <2>;
          ngpios = <8>;
          pin_mask = <0xff>;
        };
      };
    };

    nct3808_0_P1@71 {
      compatible = "nuvoton,nct38xx";
      reg = <0x71>;

      nct3808-0-p1-gpio {
        #address-cells = <1>;
        #size-cells = <0>;
        compatible = "nuvoton,nct38xx-gpio";

        gpio@0 {
          compatible = "nuvoton,nct38xx-gpio-port";
          reg = <0x0>;
          gpio-controller;
          #gpio-cells = <2>;
          ngpios = <8>;
          pin_mask = <0xdc>;
          pinmux_mask = <0xff>;
        };
      };
    };

      compatible = "nuvoton,nct38xx";
      reg = <0x75>;

      nct3808-0-P2-gpio {
        #address-cells = <1>;
        #size-cells = <0>;
        compatible = "nuvoton,nct38xx-gpio";

        gpio@0 {
          compatible = "nuvoton,nct38xx-gpio-port";
          reg = <0x0>;
          gpio-controller;
          #gpio-cells = <2>;
          ngpios = <8>;
          pin_mask = <0xdc>;
          pinmux_mask = <0xff>;
