+Device tree bindings for Microchip CAP1106, 6 channel capacitive touch sensor

+
+Optional properties:
+
+	autorepeat:		Enables the Linux input system's autorepeat
+				feature on the input device.
+
+	microchip,sensor-gain:	Defines the gain of the sensor circuitry. This
+				effectively controls the sensitivity, as a
+				smaller delta capacitance is required to
+				generate the same delta count values.
+				Valid values are 1, 2, 4, and 8.
+				By default, a gain of 1 is set.
+
+	linux,keycodes:		Specifies an array of numeric keycode values to
+				be used for the channels. If this property is
+				omitted, KEY_A, KEY_B, etc are used as
