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>;
    };
