We lose all the git history this way and it's not good. We
should apply another opnfv project repo in future.

+* TI's Keypad Controller device tree bindings
+
+TI's Keypad controller is used to interface a SoC with a matrix-type
+keypad device. The keypad controller supports multiple row and column lines.
+A key can be placed at each intersection of a unique row and a unique column.
+The keypad controller can sense a key-press and key-release and report the
+event using a interrupt to the cpu.
+
+This binding is based on the matrix-keymap binding with the following
+changes:
+
+keypad,num-rows and keypad,num-columns are required.
+
+Required SoC Specific Properties:
+- compatible: should be one of the following
+   - "ti,omap4-keypad": For controllers compatible with omap4 keypad
+      controller.
+
+Optional Properties specific to linux:
+- linux,keypad-no-autorepeat: do no enable autorepeat feature.
+
+Example:
+	keypad@4ae1c000{
+		compatible = "ti,omap4-keypad";
+		keypad,num-rows = <2>;
+		keypad,num-columns = <8>;
+		linux,keypad-no-autorepeat;
+	};
