* Cirrus Logic CLPS711X matrix keypad device tree bindings

Required Properties:
- compatible:    Shall contain "cirrus,clps711x-keypad".
- row-gpios:     List of GPIOs used as row lines.
- poll-interval: Poll interval time in milliseconds.
- linux,keymap:  The definition can be found at
                 bindings/input/matrix-keymap.txt.

Optional Properties:
- autorepeat:    Enable autorepeat feature.

Example:
	keypad {
		compatible = "cirrus,ep7312-keypad", "cirrus,clps711x-keypad";
		autorepeat;
		poll-interval = <120>;
		row-gpios = <&porta 0 0>,
			    <&porta 1 0>;

		linux,keymap = <
			MATRIX_KEY(0, 0, KEY_UP)
			MATRIX_KEY(0, 1, KEY_DOWN)
			MATRIX_KEY(1, 0, KEY_LEFT)
			MATRIX_KEY(1, 1, KEY_RIGHT)
