6.16-stable review patch. If anyone has any objections, please let me know.
Thanks for queuing this and the corresponding reverts for the other stable trees. This one patch doesn't match what I sent, the address should be changed to DP_TRAINING_PATTERN_SET not to DP_DPCD_REV, see [1]. I still think that's the correct thing to do here conforming to the DP Standard and matching what the upstream kernel does, also solving a link training issue for a DP2.0 docking station.
The reverts queued for the other stable trees are correct, since for now I do not want to change the behavior in those (i.e. those trees should continue to use the DP_DPCD_REV register matching what's been the case since the DPCD probing was introduced).
Ick, why were the values different for different branches? That feels wrong, and is why I missed that. Can you just send a fix-up patch for the one I got wrong?
thanks,
