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

The summary:
. Add display mode check operaion to mixer driver
  - Mixer IP also can put certain restrictions on the proposed
    display modes and these restrictions need to be considered
    during mode negotiation, which happens immediately after
    edid parsing.
. Set correct mode for range of resolutions
  - With this patch, the mixer driver could find the correct mode
    for the range of resolutions upto 1080 vertical lines.
. Support extra resolution for hdmi
  - This patch programs the core and timing generator registers
    using the timing data provided in drm_display_mode without
    hard-coded configurations. So this patch adds additional PHY
    configs to allow us to support more permissible resolutions
    and refresh rates.
. Add device tree support for g2d
  - This patch adds just the compatible string for exynos5250 SoC
    so that with device tree enabling, this driver can be probed.
. And bug fixes and code cleanups.
