* 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:
i2c@00000000 {
/* ... */
hyn@1A {
compatible = "hyn,cst226";
status = "okay";
reg = <0x1a>;
reset-gpio = <&gpio GPIOA_5 0x00>;
irq-gpio = <&gpio GPIOA_6 0x00>;
};
/* ... */
};
