-Device tree bindings for Microchip CAP1106, 6 channel capacitive touch sensor
-
-The node for this driver must be a child of a I2C controller node, as the
-device communication via I2C only.
-
-Required properties:
-
-	compatible:		Must be "microchip,cap1106"
-
-	reg:			The I2C slave address of the device.
-				Only 0x28 is valid.
-
-	interrupts:		Property describing the interrupt line the
-				device's ALERT#/CM_IRQ# pin is connected to.
-				The device only has one interrupt source.
-
-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
