[Intel-gfx] [PATCH 0/3] Detect DP displays based on sink count change

[Sivakumar Thulasimani]

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.

Thulasimani,Sivakumar (3):
  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
