Here's a patch that fixes clock recovery (part of link training) for me. It's on top of drm-intel-nightly branch of [1]. I don't know if it does the right thing or whether it's strictly per the DP spec, but it's worth a try. Please report whether it works for you. Also available at dp-training-pattern branch of [2].
