  18 +* Broadcom BCM6348 pin controller
  19 +
  20 +Required properties:
  21 +- compatible: Must be "brcm,bcm6348-pinctrl".
  22 +- reg: register Specifiers of dirout, dat, mode registers.
  23 +- reg-names: Must be "dirout", "dat", "mode".
  24 +- gpio-controller: Identifies this node as a GPIO controller.
  25 +- #gpio-cells: Must be <2>.
  26 +
  27 +Example:
  28 +
  29 +pinctrl: pin-controller@fffe0080 {
  30 +       compatible = "brcm,bcm6348-pinctrl";
  31 +       reg = <0xfffe0080 0x8>,
  32 +             <0xfffe0088 0x8>,
  33 +             <0xfffe0098 0x4>;
  34 +       reg-names = "dirout", "dat", "mode";
  35 +
  36 +       gpio-controller;
  37 +       #gpio-cells = <2>;
