-Required Properties:
-- compatible:		Should be "fsl,mpr121-touchkey"
-- reg:			The I2C slave address of the device.
-- interrupts:		The interrupt number to the cpu.
-- vdd-supply:		Phandle to the Vdd power supply.
-- linux,keycodes:	Specifies an array of numeric keycode values to
-			be used for reporting button presses. The array can
