Dear All, This patch series introduces a new life into Exynos IPP (Image Post Processing) subsystem by integrating it (transparently for userspace applications) with Exynos DRM core plane management. This means that all CRTC drivers transparently get support for standard features of IPP subsystem like rotation, scaling and color space conversion. Support for features not supported natively by CRTC drivers is implemented with a help of temporary framebuffers, where image data is processed by IPP subsystem before performing the scanout by a CRTC driver. This is second version of this patchset. The initial version is available here: http://thread.gmane.org/gmane.linux.kernel.samsung-soc/49743 The main change since v1 is support for color space conversion and minor fixes in the preparation patches (added support for native scaling in Exynos Video Processor module). This feature is 'experimental'. From the initial discussion I see that there is no consensus if this feature should be integrated seamplessly in Exynos DRM core or provided by a separate API. This will be further discussed. However, I would like to ask for merging patches 1-15, which are pure bugfixes and code cleanups. The patches are based on top of current exynos-drm-next branch.
