2015-05-25drm: rcar-du: Consider plane to CRTC associations in the plane allocatorLaurent Pinchart
Hardware planes are driven by the timing generator of the CRTC they are associated to. Changing the association requires restarting the CRTC group that the plane belongs to, resulting in flicker on the other CRTC. To avoid flicker as much as possible, try to allocate planes first from the free planes already associated with the target CRTC. If allocation fails then fall back to allocation from all free planes.

2015-05-22drm/i915/skl: don't fail colorkey + scaler requestChandra Konduru
There is a mplayer video failure reported with xv. This is because there is a request to do both plane scaling and colorkey. Because skl hw doesn't support plane scaling and colorkey at the same time, request is failed which is expected behavior. To make xv operate, this patch allows colorkey continue to work without using scaler. Then behavior would be similar to platforms without plane scaler support.

2015-05-22drm/i915: Enable GTT caching on gen8Ville Syrjälä
GTT caching was disabled by default on gen8 due to not working with big pages. Some information suggests that it got fixed, but still GTT caching has been left disabled by default. Or could be it just meant that the default was changed to off, and hence the problem got solved. Enable GTT caching in the hopes of some performance increase. Whether or not the big pages issue has been fixed is irrelevant at this stage since we don't use big pages. This gives me a 1-2% improvement in xonotic on my BSW. Haven't tried BDW, but supposedly it has larger TLBs so might not benefit as much. On HSW GTT caching is enabled by default.

After a bit of experimentation it looks like the best way to make this work is first disable the port on transcoder B, and then re-enable it transcoder A, and immediately disable it again.
