-Samsung 2D Graphic Accelerator using DRM frame work
-
-Samsung FIMG2D is a graphics 2D accelerator which supports Bit Block Transfer.
-We set the drawing-context registers for configuring rendering parameters and
-then start rendering.
-This driver is for SOCs which contain G2D IPs with version 4.1.
-
-Required properties:
-	-compatible:
-		should be "samsung,exynos-g2d-41".
-	-reg:
-		physical base address of the controller and length
-		of memory mapped region.
-	-interrupts:
-		interrupt combiner values.
-
-Example:
-	g2d {
-		compatible = "samsung,exynos-g2d-41";
-		reg = <0x10850000 0x1000>;
-		interrupts = <0 91 0>;
-	};
