This may be a good idea, but I prefer to add it to my todo list (or you can 
do it once this series gets submitted or as dependant patch).

I need wait_for_bit for my board/driver. Doing another set of upgrades 
will delay it.
I will also have access to dwc2 device around mid. Jan so will be able to test
"bigger" refactors.

Is it ok with you?
