1* Neonode infrared touchscreen controller
2
3Required properties:
4- compatible: must be "neonode,zforce"
5- reg: I2C address of the chip
6- interrupts: interrupt to which the chip is connected
7- gpios: gpios the chip is connected to
8  first one is the interrupt gpio and second one the reset gpio
9- x-size: horizontal resolution of touchscreen
10- y-size: vertical resolution of touchscreen
