This patch series is adding initial NV12 support for Skylake display after rebasing on latest drm-intel-nightly. Earlier I had two patch series one for 0/180 and another for 90/270. Some of the patches were already merged. This is combined series to support 0/90/180/270 and removing the ones that are already merged. Feature is tested with igt/kms_nv12 testcases. Feature is unit tested for linear/X/Y formats in 0, 90, 180, 270 orientations with combinations of 1 or 2 planes enabled along with scaling. Also negatively tested for enabling NV12 on unsupported plane. The last patch in this series depends on Tvrtko's GEM remapping for NV12 format patch series. First two patches fixing couple things in dbuf logic to allocate correct min number of dbuf blocks and use correct source width and height in 90/270 rotation cases. Update from last rev: -Resolved Ville's full review comments. -Changes were described in individual patch headers. So far R-B tag was issued for 1, 4, 6, 9 (in old series) That changes to 1, 3, 5, 8 because older 3rd patch was squashed. As number of patches are changed from previous rev due to some code refactoring, squashing and various minor updates, sending full series to keep patch numbering consistent.
