-* Samsung Image Rotator
-
-Required properties:
-  - compatible : value should be one of the following:
-	* "samsung,s5pv210-rotator" for Rotator IP in S5PV210
-	* "samsung,exynos4210-rotator" for Rotator IP in Exynos4210
-	* "samsung,exynos4212-rotator" for Rotator IP in Exynos4212/4412
-	* "samsung,exynos5250-rotator" for Rotator IP in Exynos5250
-
-  - reg : Physical base address of the IP registers and length of memory
-	  mapped region.
-
-  - interrupts : Interrupt specifier for rotator interrupt, according to format
-		 specific to interrupt parent.
-
-  - clocks : Clock specifier for rotator clock, according to generic clock
-	     bindings. (See Documentation/devicetree/bindings/clock/exynos*.txt)
-
-  - clock-names : Names of clocks. For exynos rotator, it should be "rotator".
-
-Example:
-	rotator@...10000 {
-		compatible = "samsung,exynos4210-rotator";
-		reg = <0x12810000 0x1000>;
-		interrupts = <0 83 0>;
-		clocks = <&clock 278>;
-		clock-names = "rotator";
-	};
