-* Samsung Exynos Image Scaler
-
-Required properties:
-  - compatible : value should be one of the following:
-	(a) "samsung,exynos5420-scaler" for Scaler IP in Exynos5420
-	(b) "samsung,exynos5433-scaler" for Scaler IP in Exynos5433
-
-  - reg : Physical base address of the IP registers and length of memory
-	  mapped region.
-
-  - interrupts : Interrupt specifier for scaler interrupt, according to format
-		 specific to interrupt parent.
-
-  - clocks : Clock specifier for scaler clock, according to generic clock
-	     bindings. (See Documentation/devicetree/bindings/clock/exynos*.txt)
-
-  - clock-names : Names of clocks. For exynos scaler, it should be "mscl"
-		  on 5420 and "pclk", "aclk" and "aclk_xiu" on 5433.
-
-Example:
-	scaler@...00000 {
-		compatible = "samsung,exynos5420-scaler";
-		reg = <0x12800000 0x1294>;
-		interrupts = <0 220 IRQ_TYPE_LEVEL_HIGH>;
-		clocks = <&clock CLK_MSCL0>;
-		clock-names = "mscl";
-	};
