+Ilitek ILI210x/ILI251x touchscreen controller
+
+Required properties:
+- compatible:
+ ilitek,ili210x for ILI210x
+ ilitek,ili251x for ILI251x
+
+- reg: The I2C address of the device
+
+- interrupts: The sink for the touchscreen's IRQ output
+ See ../interrupt-controller/interrupts.txt
+
+Optional properties for main touchpad device:
+
+- reset-gpios: GPIO specifier for the touchscreen's reset pin (active low)
+
+Example:
+
+ touchscreen@41 {
+ compatible = "ilitek,ili251x";
+ reg = <0x41>;
+ interrupt-parent = <&gpio4>;
+ interrupts = <7 IRQ_TYPE_EDGE_FALLING>;
+ reset-gpios = <&gpio5 21 GPIO_ACTIVE_LOW>;
+ };
