Merge branch 'exynos-drm-next' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

Inki writes:
      This is initial pull request for Exynos. It includes a big change
       that it makes drm_display_mode for timings parameters to be used
       for exynos4 and exynos5 commonly and cleans up unnecessary codes.
       And also it adds device tree support for fimd to get timing values
       and interrupt source from dts file.

       In addition, one more patch, device tree support feature for Exynos
       FIMC, is being reviewed. This patch was posted a little ago like below,
            http://www.mail-archive.com/linux-samsung-soc@vger.kernel.org/msg17568.html

       So we are going to request git pull one more time after reviewed.

-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>;
-	};
