From: "Thulasimani,Sivakumar" <sivakumar.thulasimani at intel.com>
These patches together help detect DP displays on short pulse HPD
and pass the respective compliance test case (4.2.2.8)
v2: modifed first patch so we will read sink_count independent of
downstream ports availablility.
v3: split first patch so crtc enabled check is done in one patch
and rest of sink_count changes in second patch.
Thulasimani,Sivakumar (4):
drm/i915: read dpcd 0 - 12 & link_status always
drm/i915: read sink_count dpcd always
drm/i915: Save sink_count for tracking changes to it
drm/i915: force full detect on sink count change
