Merge tag 'exynos-drm-next-for-v4.15' of git://git.kernel.org/pub/scm/linux/kernel/git/daeinki/drm-exynos into drm-next

- Improved HDMI and Mixer drivers
  . It moves mode setup and plane update code to commit
    like other CRTC drivers
  . It makes mode commit to be called in enable callback only one time
  . some cleanup and fixup to HDMI and Mixer drivers.
  . It adds 1024x768, 1280x1024 and 1366x768 modes support
- Added HDMI audio interface driver
  . As of now, HDMI audio worked on boards with external audio codec connected
    in parallel with the HDMI audio transmitter's I2S interface.
    This patch is required to support HDMI audio properly.
