Currently, all HPD interrupt handling must go through the HPD state
machine.
This has caused many issues where the DRM framework assumes that DP is
in one state while the state machine is stuck in another state.
As discussed here [1], this series:
- Removes the state machine
- Moves link training to atomic_enable()
- Changes the detect() behavior to return true if a display is
physically
plugged in (as opposed to if the DP link is ready).
- Remove event queue and move internal HPD handling to hpd_notify()
To correctly detect the displays which are plugged on boot on the boards
which use dp-connector devices, this series depends on [2]. USB-C and
eDP panels are handled natively.

Unfortunately this currently seems to mostly break link training with
USB-C, on x1e80100-dell-latitude-7455:

Actually looks like that might've been due to having applied the [2]
dp-connector series from above.
Interesting. The series only affects dp-connector. It can't affect
pmic-glink usecase.
Removed it and rebooted, now plugging and unplugging multiple times between
the 2 ports works fine.
Except unplug is still not reliable, the "ghost" monitor often remains after
unplugging.
Does the patch at [3] fix the issue?

Yes!
Overall works better than ever now, looks like I can unplug the cable
with the laptop closed and then open it and it's all fine, and even play
with dual-role / gadget mode USB and plug the alt-mode/dock cable back
in and it doesn't crash.
Still, rare link training failures can happen, e.g.:
Almost nothing is logged to dmesg, literally I've only seen this line once:
[drm:msm_dp_panel_read_sink_caps [msm]] *ERROR* panel edid read failed
You might want to use drm.debug=0x100 to get DP-related messages.
