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- reset-gpios: reset gpio the chip is connected to
8- x-size: horizontal resolution of touchscreen
9- y-size: vertical resolution of touchscreen
10
11Optional properties:
12- irq-gpios : interrupt gpio the chip is connected to
13- vdd-supply: Regulator controlling the controller supply
14
15Example:

17	i2c@00000000 {
18		/* ... */
