* ARM Cirrus Logic CLPS711X SYSFLG1 MCTRL GPIOs

Required properties:
- compatible: Should contain "cirrus,clps711x-mctrl-gpio".
- 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.

Example:
	sysgpio: sysgpio {
		compatible = "cirrus,ep7312-mctrl-gpio",
			     "cirrus,clps711x-mctrl-gpio";
		gpio-controller;
		#gpio-cells = <2>;
	};
