Subject: [PATCH 0/7] drm/msm/dp: Simplify DPCD related code with helpers

This driver open-codes a few of the DPCD register reads when it can be
simplified by using the helpers instead. This series reworks the MSM DP
driver to use the DPCD helpers and removes some dead code along the way.
There's the potential for even more code reduction around the test
registers, but I haven't tried to do that yet.

Stephen Boyd (7):
  drm/msm/dp: Replace open-coded drm_dp_read_dpcd_caps()
  drm/msm/dp: Use drm_dp_read_sink_count() helper
  drm/msm/dp: Remove dead code related to downstream cap info
  drm/msm/dp: Remove aux_cfg_update_done and related code
  drm/msm/dp: Simplify with drm_dp_{max_link_rate,max_lane_count}()
  drm/msm/dp: Inline dp_link_parse_sink_count()
  drm/msm/dp: Remove dp_display_is_ds_bridge()
