		Himax touch controller

		The Himax touch controller is connected to host processor
		via i2c. The controller generates interrupts when the
		user touches the panel. The host controller is expected
		to read the touch coordinates over i2c and pass the coordinates
		to the rest of the system.

		Required properties:

		- compatible : Should be "himax,hxcommon"
		- reg : i2c slave address of the device.
		- interrupt-parent : parent of interrupt.
		- himax,irq-gpio : irq gpio.
		- himax,reset-gpio : reset gpio.
		- vdd-supply : Power supply needed to power up the device.
		- avdd-supply : Power source required to power up i2c bus.
		- himax,panel-coords : panel coordinates for the chip in pixels.
		It is a four tuple consisting of min x,
		min y, max x and max y values.
		- himax,display-coords : display coordinates in pixels. It is a four
		tuple consisting of min x, min y, max x and
		max y values

		Optional properties:
		- himax,3v3-gpio : gpio acting as 3.3 v supply.
		- himax,report_type : Multi-touch protocol type. Default 0.
		0 for protocol A, 1 for protocol B.
