You went to the other extreme of combining everything (host/gadget/drd) together
which again makes this very hard to review.

I think what Felipe meant was to only combine the gadget driver code into one patch.

The series could be split into 6 patches like so.
-dt binding
-pci glue
-core driver
-host driver
-gadget driver
-drd driver
