+* Samsung S6SY761 touchscreen controller
+
+Required properties:
+- compatible : must be "samsung,s6sy761"
+- reg : I2C slave address, (e.g. 0x48)
+- interrupt-parent : the phandle to the interrupt controller which provides
+ the interrupt
+- interrupts : interrupt specification
+- avdd-supply : analogic power supply
+- vdd-supply : power supply
+
+Optional properties:
+- touchscreen-size-x : see touchscreen.txt. This property is embedded in the
+ device. If defined it forces a different x resolution.
+- touchscreen-size-y : see touchscreen.txt. This property is embedded in the
+ device. If defined it forces a different y resolution.
+
+Example:
+
+i2c@00000000 {
+
+ /* ... */
+
+ touchscreen@48 {
+ compatible = "samsung,s6sy761";
+ reg = <0x48>;
+ interrupt-parent = <&gpa1>;
+ interrupts = <1 IRQ_TYPE_NONE>;
+ avdd-supply = <&ldo30_reg>;
+ vdd-supply = <&ldo31_reg>;
+ touchscreen-size-x = <4096>;
+ touchscreen-size-y = <4096>;
+ };
+};
