[PATCH 0/4] drm/msm/dp, phy: qcom: improve DP Type-C reconnect handling

[Saurabh Anand]

This series improves the Qualcomm DP Type-C bring-up and reconnect paths
by handling PHY initialization races and link-training corner cases more
consistently.

The fixes cover races and link-training corner cases in the Qualcomm DP
Type-C path. They prevent Type-C mux switching while the DP PHY is still
initializing, avoid unnecessary retraining after a successful link train,
skip LTTPR setup when no LTTPRs are present, and keep the downgrade retry
path running across transient AUX disconnects when the cable is still
plugged.

Together these changes make DP reconnect and orientation-switch
handling more robust, especially when AUX link status briefly disagrees
with Type-C cable presence during reconnect.
