+* Samsung Exynos5 SCALER device
+
+SCALER is used for scaling, blending, color fill and color space
+conversion on EXYNOS[5420/5410] SoCs.
+
+Required properties:
+- compatible: should be "samsung,exynos5420-scaler" or
+			"samsung,exynos5410-scaler"
+- reg: should contain SCALER physical address location and length
+- interrupts: should contain SCALER interrupt specifier
+- clocks: should contain the SCALER clock phandle and specifier pair for
+		each clock listed in clock-names property, according to
+		the common clock bindings
+- clock-names: should contain exactly one entry
+		- "scaler" - IP bus clock
+
+Example:
+	scaler_0: scaler at 12800000 {
+		compatible = "samsung,exynos5420-scaler";
+		reg = <0x12800000 0x1000>;
+		interrupts = <0 220 0>;
+		clocks = <&clock 381>;
+		clock-names = "scaler";
+	};
