Backporting it to stable is what is causing most of the issues today, combined with a number of broken DT descriptions. So i would be happy for stable to get a patch which looks at the strapping, sees ID is enabled via strapping, warns the DT blob is FUBAR, and then ignores the requested PHY-mode. That gives developers time to fix their broken DT. Andrew
