* 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@12800000 {

		compatible = "samsung,exynos5420-scaler";

		reg = <0x12800000 0x1294>;

		interrupts = <0 220 IRQ_TYPE_LEVEL_HIGH>;

		clocks = <&clock CLK_MSCL0>;

		clock-names = "mscl";

	};
