Sorry no idea about am3517 for musb. Sounds like it's similar to the
am335x though. The USB PHY(s) is probably different though and maybe
you need a separate drivers/phy driver. Maybe check the phy drivers
we have for davinci/dm814x/dm816x, maybe it's similar to those if
not the same as on am335x.

Regards,

Tony
