+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>;
+ };
