I think all, not most DWC drivers should be aligned. Plus the code here is pretty much the same, so I'm working on moving all this to the common DWC code. Drivers that need to bring up the link will need to implement .start_link() (currently only used for EP mode). Most of the time that is just setting the LTSSM bit which Synopsys thought letting every vendor do their own register for was a good idea. Sigh. Rob
