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.
