From: Andrzej Pietrasiewicz <andrzej.p@xxxxxxxxxxx>
Exynos Scaler is a hardware module, which processes graphic data fetched
from memory and transfers the resultant dato another memory buffer.
Graphics data can be up/down-scaled, rotated, flipped and converted color
space. Scaler hardware modules are a part of Exynos5420 and newer Exynos
SoCs.

+* 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".
+
+Example:
+ scaler@12800000 {
+ compatible = "samsung,exynos5420-scaler";
+ reg = <0x12800000 0x1294>;
+ interrupts = <0 220 IRQ_TYPE_LEVEL_HIGH>;
+ clocks = <&clock CLK_MSCL0>;
+ clock-names = "mscl";
+ };
