-* Samsung S6SY761 touchscreen controller
-
-Required properties:
-- compatible		: must be "samsung,s6sy761"
-- reg			: I2C slave address, (e.g. 0x48)
-- 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>;
-	};
-};
