>From the log on 2/26, it looks like the AUX write is failing at the beginning
of link training. So the sink device wouldn't be aware that the source device
was attempting to train it.

It's unclear why we try to continue link training when clearly the sink device
hasn't responded. I'll see if I can track this down on a ByT here in Oregon
since mine doesn't have the eDP display on it.
