Himax Touch Controller

Required properties:

 - compatible		: Should be "himax,hxcommon"
 - reg			: I2C slave address of the device.
 - interrupt-parent	: Parent of interrupt.
 - interrupts		: Configuration of touch panel controller interrupt
			GPIO.
 - interrupt-gpios	: Interrupt gpio which is to provide interrupts to
			host, same as "interrupts" node.
 - reset-gpios		: Reset gpio to control the reset of chip.
 - 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:

 - avdd-supply		: Power supply needed to power up the device, this is
			for fixed voltage external regulator.
 - vdd-supply		: Power supply needed to power up the device, when use
			external regulator, do not add this property.
 - 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.

Example:
&i2c_3 {
	status = "okay";
	himax_ts@48 {
		compatible = "himax,hxcommon";
		reg = <0x48>;
		interrupt-parent = <&tlmm>;
		interrupts = <65 0x2>;
		vdd-supply = <&pm8953_l10>;
		avdd-supply = <&pm8953_l5>;
		pinctrl-names = "pmx_ts_active","pmx_ts_suspend","pmx_ts_release";
		pinctrl-0 = <&ts_int_active &ts_reset_active>;
		pinctrl-1 = <&ts_int_suspend &ts_reset_suspend>;
		pinctrl-2 = <&ts_release>;
		himax,panel-coords = <0 800 0 1280>;
		himax,display-coords = <0 800 0 1280>;
		himax,irq-gpio = <&tlmm 65 0x2008>;
		//himax,rst-gpio = <&tlmm 64 0x0>;
		report_type = <1>;
	};
