+SKY81452 bindings
+
+Required properties:
+- compatible	: Must be "skyworks,sky81452"
+- reg		: I2C slave address
+
+Required child nodes:
+- backlight	: container node for backlight following the binding
+		in video/backlight/sky81452-backlight.txt
+- regulator	: container node for regulators following the binding
+		in regulator/sky81452-regulator.txt
+
+Example:
+
+	sky81452@2c {
+		compatible = "skyworks,sky81452";
+		reg = <0x2c>;
+
+		backlight {
+			compatible = "skyworks,sky81452-backlight";
+			name = "pwm-backlight";
+			enable = <0x3F>;
+			ignore-pwm;
+		};
+
+		regulator {
+			compatible = "skyworks,sky81452-regulator";
+			regulator-name = "touch_en";
+			regulator-min-microvolt = <4500000>;
+			regulator-max-microvolt = <8000000>;
+		};
