  19 +* Broadcom BCM63268 pin controller
  20 +
  21 +Required properties:
  22 +- compatible: "brcm,bcm6362-pinctrl"
  23 +- regs: register specifiers of data, dirout, led, mode, ctrl, basemode,
  24 +       and miscmisc registers.
  25 +- reg-names: must be "data", "dirout", "led", "mode", "ctrl", "basemode",
  26 +            "miscmisc".
  27 +- gpio-controller: identifies this node as a gpio controller.
  28 +- #gpio-cells: must be 2.
  29 +
  30 +Example:
  31 +
  32 +pinctrl: pin-controller@100000c0 {
  33 +       compatible = "brcm,bcm63268-pinctrl";
  34 +       reg = <0x100000c0 0x8>,
  35 +             <0x100000c8 0x8>,
  36 +             <0x100000d0 0x4>,
  37 +             <0x100000d8 0x4>,
  38 +             <0x100000dc 0x4>,
  39 +             <0x100000f8 0x4>,
  40 +             <0x100018a0 0x4>;
  41 +       reg-names = "dirout", "data", "led", "mode",
  42 +                   "ctrl", "basemode", "miscmisc";
  43 +
  44 +       gpio-controller;
  45 +       #gpio-cells = <2>;
