Alexander, I don't know if you are still interested in this but if you check if my findings help I would definitely like to know about this.
First of all, thanks for the amazing reversing work and explanation! I only silently followed the discussions on GitHub about the RPi, since I didn't have any findings to contribute.
I did not check networking yet but eliminated -92 errors for keyboard and mouse.
I integrated your "brutal" fix and did a short test with a RPi 3. Networking seems to work and the error seems to be eliminated.
During my attempts I ported this new driver and it did not help so probably fixing dma can help on previous versions of the driver too.
I used it in conjunction with the dwc driver, so your hypothesis seems to be correct.
Best regards, Alexander
