+* 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@12800000 {
+		compatible = "samsung,s5pv210-g2d";
+		reg = <0x12800000 0x1000>;
+		interrupts = <0 89 0>;
+		clocks = <&clock 177>, <&clock 277>;
+		clock-names = "sclk_fimg2d", "fimg2d";
+	};
