[GIT PULL] exynos-drm-next-v2

Hi Dave,

   Just added new IPP driver since previous pull request.

   We rewrited Exynos DRM IPP driver due to below limitations and issues,
   - Userspace API covers memory-2-memory picture operations together with
     CRTC writeback and duplicating features, which belongs to video plane.
   - Lack of support of the all required image formats (for example NV12
     Samsung-tiled cannot be used due to lack of pixel format modifier
     support).
   - Userspace API designed only to mimic hardware behaviour, not easy to
     understand.
   - Lack of proper input validation in the core, drivers also didn't do that
     correctly, so it was possible to set incorrect parameters and easil
     trigger IOMMU fault or memory trash.
   - Drivers were partially disfunctional or supported only a subset of modes.

   There is no user who uses old API excepting Tizen platform[1]
   we are developing, and we will update the platform with new version.

   Sample applications for new version,

   Please kindly let me know if there is any problem.

  drm/exynos: Add driver for Exynos Scaler module (2017-11-09 19:59:22 +0900)

----------------------------------------------------------------
- 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.
- Remove old version of Exynos DRM IPP driver and add new version.
- Convert each post processing driver - Rotator, GScaler and FIMC - to new API.
