-* 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
-
