* Neonode infrared touchscreen controller



Required properties:

- compatible: must be "neonode,zforce"

- reg: I2C address of the chip

- interrupts: interrupt to which the chip is connected

- reset-gpios: reset gpio the chip is connected to

- x-size: horizontal resolution of touchscreen

- y-size: vertical resolution of touchscreen



Optional properties:

- irq-gpios : interrupt gpio the chip is connected to

- vdd-supply: Regulator controlling the controller supply



Example:



	i2c@00000000 {

		/* ... */



		zforce_ts@50 {

			compatible = "neonode,zforce";

			reg = <0x50>;

			interrupts = <2 0>;

			vdd-supply = <&reg_zforce_vdd>;



			reset-gpios = <&gpio5 9 0>; /* RST */

			irq-gpios = <&gpio5 6 0>; /* IRQ, optional */



			x-size = <800>;

			y-size = <600>;

		};



		/* ... */

	};
