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
