From: Ville Syrjälä <ville.syrjala@xxxxxxxxxxxxxxx> Ok, so while looking at the upfront link training stuff, it became obvious that we needs to do something about the link training stuff that we have in hpd_pulse currently. The thing is, you can't grab any modeset locks from that work since it could lead to a deadlock with MST sideband stuff. So here's a quick attempt at moving the stuff over to the hotplug work. I've included a few other things at the start just to make the surroundings a little less broken (some of that I've posted before). And there are a few potentially helpful snippets at the end too. The main meat is in the middle.
