+* Samsung 2D Graphics Accelerator
+
+Samsung FIMG2D is a 2D graphics accelerator which supports Bit Block Transfer.
+We set the drawing-context registers for configuring the rendering parameters
+and then start rendering.
+The G2D has V4L2 as well as DRM framework based driver support.
+
+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
+	(b) "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.
+
+Optional properties:
+  - samsung,power-domain : power-domain property defined with a phandle
+			   to respective power domain.
+
+Example:
+	g2d@12800000 {
+		compatible = "samsung,s5pv210-g2d";
+		reg = <0x12800000 0x1000>;
+		interrupts = <0 89 0>;
+		samsung,power-domain = <&pd_lcd0>;
+		status = "disabled";
+	};
