The last outstanding issue from Sergei seems to be additional comments
describing why MUSB_OTG is OK to use.
Prakash/Constantine,
Did you have to make any hardware changes when testing host/gadget on
DM6446 EVM? Or change in kernel configuration?
It appears that there is no way to choose any of the config option
affecting the mode setting. Right now it seems to be just defaulting to
MUSB_UNDEFINED. Setting it to MUSB_OTG would be better than that.
Thanks,
Sekhar
