Maybe the DT syscfg node shouldn't be a plain syscon , but rather there should be an actual driver which binds to the syscfg DT node and configures all these hardware details early on boot ? The USB controller drivers will start only later, when the syscfg configuration is already set in the hardware by this (future) driver, since they depend on the syscfg node and the PHY subnodes. Maybe that is the way to fix the MP21 without having USB controller glue ?Hello Marek, Ok, I'll think more about it regarding MP21. Let's continue on current series without any additional glue driver for MP23/25.
There is really no rush, if you can come up with something for MP21 that does not require the controller glue, that would be real nice. Thank you for your help !
