[Intel-gfx] [PATCH 00/20] skylake display scalers

[Chandra Konduru]

primary changes in this version are:
- moved changes to state from commit patch to check path (Matt)
- squashed few patches into others (Matt)
- rebased colorkey related patches ontop of recent updates (Daniel)
- rebased all patches onto today's drm-intel-nightly (me)
- initialized colorkey to NONE (me)
- changed primary plane src values to regular integers align with sprite (me)
- used updated get display clock function (me)

Numbers of patches updated in this version:
 4, 6, 8, 9, 11, 18, 19, 20

Sending full patch series for completeness. Individual patch headers
have additional details on changes. This series should cleanly
merge to latest drm-intel-nighly.
