+Cirrus Logic CLPS711X GPIO controller
+
+Required properties:
+- compatible: Should be "cirrus,ep7209-gpio"
+- reg: Physical base GPIO controller registers location and length.
+ There should be two registers, first is DATA register, the second
+ is DIRECTION.
+- gpio-controller: Marks the device node as a gpio controller.
+- #gpio-cells: Should be two. The first cell is the pin number and
+ the second cell is used to specify the gpio polarity:
+ 0 = active high
+ 1 = active low
+
+Note: Each GPIO port should have an alias correctly numbered in "aliases"
+node.
+
+Example:
+
+aliases {
+ gpio0 = &porta;
+};
+
+porta: gpio@80000000 {
+ compatible = "cirrus,ep7312-gpio","cirrus,ep7209-gpio";
+ reg = <0x80000000 0x1>, <0x80000040 0x1>;
+ gpio-controller;
+ #gpio-cells = <2>;
+};
