   2 -----------------------------------------------------
   3
   4 Required properties:
   5 - compatible : "via,vt8500-gpio", "wm,wm8505-gpio"
   6         or "wm,wm8650-gpio" depending on your SoC
   7 - reg : Should contain 1 register range (address and length)
   8 - #gpio-cells : should be <3>.
   9         1) bank
  10         2) pin number
  11         3) flags - should be 0

  13 Example:
  14
  15         gpio: gpio-controller@d8110000 {
  16                 compatible = "via,vt8500-gpio";
  17                 gpio-controller;
  18                 reg = <0xd8110000 0x10000>;
  19                 #gpio-cells = <3>;
  20         };
  21
  22         vibrate {
  23                 gpios = <&gpio 0 1 0>; /* Bank 0, Pin 1, No flags */
  24         };
