+* Samsung Exynos5 M-Scaler device
+
+M-Scaler is used for scaling, blending, color fill and color space
+conversion on EXYNOS5 SoCs.
+
+Required properties:
+- compatible: should be "samsung,exynos5-mscl"
+- reg: should contain M-Scaler physical address location and length.
+- interrupts: should contain M-Scaler interrupt number
+- clocks: should contain the clock number according to CCF
+- clock-names: should be "mscl"
+
+Example:
+
+ mscl_0: mscl@0x12800000 {
+ compatible = "samsung,exynos5-mscl";
+ reg = <0x12800000 0x1000>;
+ interrupts = <0 220 0>;
+ clocks = <&clock 381>;
+ clock-names = "mscl";
+ };
+
+Aliases:
+Each M-Scaler node should have a numbered alias in the aliases node,
+in the form of msclN, N = 0...2. M-Scaler driver uses these aliases
+to retrieve the device IDs using "of_alias_get_id()" call.
+
+Example:
+
+aliases {
+ mscl0 =&mscl_0;
+ mscl1 =&mscl_1;
+ mscl2 =&mscl_2;
+};
