Increasing the priority to highest because it affects ICL. commit 12a6c931beffeaaa350ef562e91e49918b4b3e68 Author: Paulo Zanoni <paulo.r.zanoni@intel.com> Date: Tue Jul 31 17:46:14 2018 -0700 drm/i915/icl: avoid unclaimed PLANE_NV12_BUF_CFG register We don't have proper watermark NV12 support on ICL due to differences in how it should be implemented. In commit 234059da0f33 ("drm/i915/icl: NV12 y-plane ddb is not in same plane") we avoided writing the non-existent PLANE_NV12_BUF_CFG registers but we forgot to also avoid them on the hardware state readout. While the code is still not correct, at least now we can avoid unclaimed register error messages when dealing with RGB formats, which makes CI happier. Also add some FIXME comments in order to make it even more clear that there's still work to do.
