3Required properties:
4- compatible: Should contain "cirrus,ep7209-mctrl-gpio".
5- gpio-controller: Marks the device node as a gpio controller.
6- #gpio-cells: Should be two. The first cell is the pin number and
7 the second cell is used to specify the gpio polarity:
8 0 = Active high,
9 1 = Active low.

12 sysgpio: sysgpio {
13 compatible = "cirrus,ep7312-mctrl-gpio",
14 "cirrus,ep7209-mctrl-gpio";
15 gpio-controller;
16 #gpio-cells = <2>;
