  18 +* Broadcom BCM6328 pin controller
  19 +
  20 +Required properties:
  21 +- compatible: Must be "brcm,bcm6328-pinctrl".
  22 +- reg: Register specifies of dirout, dat, mode, mux registers.
  23 +- reg-names: Must be "dirout", "dat", "mode", "mux".
  24 +- gpio-controller: Identifies this node as a GPIO controller.
  25 +- #gpio-cells: Must be <2>
  26 +
  27 +Example:
  28 +
  29 +pinctrl: pin-controller@10000080 {
  30 +       compatible = "brcm,bcm6328-pinctrl";
  31 +       reg = <0x10000080 0x8>,
  32 +             <0x10000088 0x8>,
  33 +             <0x10000098 0x4>,
  34 +             <0x1000009c 0xc>;
  35 +       reg-names = "dirout", "dat", "mode", "mux";
  36 +
  37 +       gpio-controller;
  38 +       #gpio-cells = <2>;
