This is a good news, one or two month ago we were looking for such a patch!
Finally we take an old version that we adapt to just make it works. Our future
plan was to clean it up and submit a correct version. As your version seems more
advanced,we will take it and test it for our board. I hope be able to feed
information by the end of the week.

Our board use the 6-pin DP/DM PHY mode, so it will be a new mode to be validated
