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"
+                 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";
+       };
