   3 Required properties:
   4 - compatible: Must be "technologic,ts4800-gpio".
   5 - #gpio-cells: Should be two. The first cell is the pin number.
   6 - reg: Physical base address of the controller and length
   7        of memory mapped region.

  12 Example:
  13
  14 gpio1: gpio {
  15         compatible = "technologic,ts4800-gpio";
  16         reg = <0x10020 0x6>;
  17         ngpios = <8>;
  18         gpio-controller;
  19         #gpio-cells = <2>;
  20 };
