+MOXA ART GPIO Controller
+
+Required properties:
+
+- #gpio-cells : Should be 2, The first cell is the pin number,
+ the second cell is used to specify polarity:
+ 0 = active high
+ 1 = active low
+- compatible : Must be "moxa,moxart-gpio"
+- reg : Should contain registers location and length
+
+Example:
+
+ gpio: gpio@98700000 {
+ gpio-controller;
+ #gpio-cells = <2>;
+ compatible = "moxa,moxart-gpio";
+ reg = <0x98700000 0xC>;
+ };
