I pushed those to dinq.
This series seems to break eDP detection on BDW RVP.
I presume this is due to the sink count check. Can you add debug logging
to print intel_dp->sink_count after it's been read in
intel_dp_get_dpcd() please?
intel_dp->sink_count is zero here. (raw value, before the
DP_GET_SINK_COUNT.)
Also, intel_dp_dpcd_read_wake suggests a possibility for reading garbage
with not overly confident wording for the workaround there.
Then the question is, is this just because you have an RVP with who
knows what panel, or do we have to take into account potentially broken
panels too? Then I assume the fix would be to to ignore sink count for
eDP.
No idea. :)
