But what I can do is test this on an x86 device using a pi3usb30532 mux for USB super-speed and DP-alt-mode muxing / orientation switching. I'm going to wait a bit with doing that till this has had some reviews and possibly also some newer versions because of those reviews. If you haven't received a Tested-by from me when this looks like it is ready for merging please ping me.

I realize that I failed to mention that I don't have this hardware, so I've not been able to test it myself. > I'm going to wait a bit with doing that till this has had > some reviews and possibly also some newer versions because > of those reviews.
