  18 +* Broadcom BCM6318 pin controller
  19 +
  20 +Required properties:
  21 +- compatible: Must be "brcm,bcm6318-pinctrl".
  22 +- regs: Register specifiers of dirout, dat, mode, mux, and pad registers.
  23 +- reg-names: Must be "dirout", "dat", "mode", "mux", "pad".
  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,bcm6318-pinctrl";
  31 +       reg = <0x10000080 0x08>,
  32 +             <0x10000088 0x08>,
  33 +             <0x10000098 0x04>,
  34 +             <0x1000009c 0x0c>,
  35 +             <0x100000d4 0x18>;
  36 +       reg-names = "dirout", "dat", "mode", "mux", "pad";
  37 +
  38 +       gpio-controller;
  39 +       #gpio-cells = <2>;
