+* Sitronix st1232 touchscreen controller
+
+Required properties:
+- compatible: must be "sitronix,st1232"
+- reg: I2C address of the chip
+- interrupts: interrupt to which the chip is connected
+
+Optional properties:
+- gpios: a phandle to the reset GPIO
+
+Example:
+
+        i2c@00000000 {
+                /* ... */
+
+                touchscreen@55 {
+                        compatible = "sitronix,st1232";
+                        reg = <0x55>;
+                        interrupts = <2 0>;
+                        gpios = <&gpio1 166 0>;
