The comment about Gen3 speed above reminds me that you took some shortcuts to get here and you removed support for some features as well as some bug workarounds in the process. I'm guessing some of them won't be necessary because they are only for prototype hardware or for early boot loader versions that don't yet set up the hardware right, but others actually need to come back. That is usually a good approach, but I'd also like to make sure we can deal with them nicely when you have to add them back later, and don't have to add ugly extensions to the DT binding to support the old dtb files. Can you list (also in the changelog) the parts of the driver that you have taken out for now and that you expect to add back at later stage? I think that would be helpful for perspective. Regarding the support for multiple link speeds, how do you think it will be done? Can you have a driver-side link speed autoconfiguration, or do you have to add DT properties and let the driver know about the attached device?
