Three weeks have passed, so resending. Could i maybe excite somebody to
review/merge at least some of the really trivial but important patches
to fix regressions back-ported to all stable kernels, mostly in Intel
kms + DP legacy in this series before the 4.8 merge window closes?
Especially patch 2, "[PATCH 2/5] drm/i915/dp: Revert "drm/i915/dp: fall
back to 18 bpp when sink capability is unknown" a revert acked by Jani
for a patch of him, and patch 5 "[PATCH 5/5] drm/edid: Set 8 bpc color
depth for displays with "DFP 1.x compliant TMDS"?
Patch 5/5 would make our EDID parsing for DVI more complete and if also
back-ported to stable would at least prevent the worst fallout for
current users if patch 2/5 doesn't get applied.
thanks,

Updated series to fix the regressions introduced into stable
kernels for active Displayport to dual-link DVI converters and
for active Displayport to VGA converters. Also to fix this stuff
better for Linux 4.8.
Patch 1 + 2 are needed to fix the regressions in the stable
kernels. These are meant for easy backporting to all affected
kernels.
Patch 3: A DP helper for parsing sink bpc from DP aux data to
assist drivers if they can't get bpc from EDID.
Patch 4: Make intel kms use patch 3.
Patch 5: Make the EDID parser recognize the "DFP1.x compatible TMDS"
bit by which DVI sinks can declare they support at least 8 bpc according
to DFP spec. This one if applied would let me sleep so much better, as
the common special display equipment for neuroscience research, which is
all DVI based atm., sets that bit in its EDID 1.3.
Thanks,
