   8 - reg: I2C slave address
   9 - gpio-controller: Marks the device node as a GPIO controller.
  10 - #gpio-cells: Should be <2>. The first cell is the gpio number and

  15 pld@56 {
  16         compatible = "gateworks,pld-gpio";
  17         reg = <0x56>;
  18         gpio-controller;
  19         #gpio-cells = <2>;
