+Ilitek I2C 23XX/25XX/Lego Series Touch ICs
+
+Required properties:
+- compatible		: Must be equal to one of following:
+			  "ilitek,ili2520"
+			  "ilitek,ili2510"
+- reg			: I2C slave address for touch device.
+- reset-gpios		: GPIO output high to reset pin of touch device.
+- irq-gpios		: GPIO as active low input from touch irq pin.
+
+Example:
+        &i2c1 {
+                /* ... */
+
+                touchscreen@41 {
+			compatible = "ilitek,ili2520";
+                        reg = <0x41>;
+			irq-gpios = <&gpio1 13 0>;
+			reset-gpios = <&gpio1 14 GPIO_ACTIVE_HIGH>;
+                };
+
+                /* ... */
+        };
