-* Samsung 2D Graphics Accelerator
-
-Required properties:
-  - compatible : value should be one among the following:
-	(a) "samsung,s5pv210-g2d" for G2D IP present in S5PV210 & Exynos4210 SoC
-	(b) "samsung,exynos4212-g2d" for G2D IP present in Exynos4x12 SoCs
-	(c) "samsung,exynos5250-g2d" for G2D IP present in Exynos5250 SoC
-
-  - reg : Physical base address of the IP registers and length of memory
-	  mapped region.
-
-  - interrupts : G2D interrupt number to the CPU.
-  - clocks : from common clock binding: handle to G2D clocks.
-  - clock-names : names of clocks listed in clocks property, in the same
-		  order, depending on SoC type:
-		  - for S5PV210 and Exynos4 based SoCs: "fimg2d" and
-		    "sclk_fimg2d"
-		  - for Exynos5250 SoC: "fimg2d".
-
-Example:
-	g2d@...00000 {
-		compatible = "samsung,s5pv210-g2d";
-		reg = <0x12800000 0x1000>;
-		interrupts = <0 89 0>;
-		clocks = <&clock 177>, <&clock 277>;
-		clock-names = "sclk_fimg2d", "fimg2d";
-	};
