I can't find good answer about this online.
What is the difference in DWCOTG and DWC2 drivers?
I see both of them work on RPI3 but haven't tested them much.
Is DWC2 newer or somehow better?
I remember those dwc_otg configuration parameters few years ago until it become quite stable.
I never saw anything introducing dwc2 or explaining what is it's role, except that it's used for RPI Zero (in device tree).
Does anyone know something deeper about it?
