-* 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";
- };
