   1 MOXA ART GPIO Controller
   2
   3 Required properties:
   4
   5 - #gpio-cells : Should be 2, The first cell is the pin number,
   6                 the second cell is used to specify polarity:
   7                         0 = active high
   8                         1 = active low
   9 - compatible : Must be "moxa,moxart-gpio"
  10 - reg : Should contain registers location and length
  11
  12 Example:
  13
  14         gpio: gpio@98700000 {
  15                 gpio-controller;
  16                 #gpio-cells = <2>;
  17                 compatible = "moxa,moxart-gpio";
  18                 reg =   <0x98700000 0xC>;
  19         };
