+* Neonode infrared touchscreen controller
+
+Required properties:
+- compatible: must be "hyn,cst226"
+- 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:
