Dave Airlie 64c026e28d 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.

************************************************************

The Direct Rendering Manager (drm) is a device-independent kernel-level
device driver that provides support for the XFree86 Direct Rendering
Infrastructure (DRI).

The DRM supports the Direct Rendering Infrastructure (DRI) in four major
ways:

    1. The DRM provides synchronized access to the graphics hardware via
       the use of an optimized two-tiered lock.

    2. The DRM enforces the DRI security policy for access to the graphics
       hardware by only allowing authenticated X11 clients access to
       restricted regions of memory.

    3. The DRM provides a generic DMA engine, complete with multiple
       queues and the ability to detect the need for an OpenGL context
       switch.

    4. The DRM is extensible via the use of small device-specific modules
       that rely extensively on the API exported by the DRM module.


Documentation on the DRI is available from:
