[PATCH 0/5] drm/i915/dp: Fix LTTPR detection

[Imre Deak]

Fix the DP LTTPR PHY detection, avoiding a loss of link synchronization
when the detection is done while the link through the LTTPR is active.
Also dump the LTTPR PHY descriptors to help debugging similar issues.

Imre Deak (5):
  drm/i915/dp: Don't switch the LTTPR mode on an active link
  drm/i915/dp: Reset cached LTTPR count if number of LTTPRs is
    unsupported
  drm/i915/dp: Keep cached LTTPR mode up-to-date
  drm/dp: Add the LTTPR PHY OUI DPCD register
  drm/i915/dp: Dump the LTTPR PHY descriptors
