[Constantine Shulyupin]

From: Constantine Shulyupin <const@MakeLinux.com>

Remove USB configuration in arch/arm/mach-davinci/usb.c accordingly 
CONFIG_USB_MUSB_OTG CONFIG_USB_MUSB_PERIPHERAL CONFIG_USB_MUSB_HOST 
and set MUSB_OTG configuration by default
because this configuration options are removed from Kconfig.

Tested it on DM6446-EVM for host mode with MSC thumb drive and gadget 
mode with g-ether. It works.

I sent a similiar patch here:

http://comments.gmane.org/gmane.linux.usb.general/54512

If the issues, mentioned from Sergei for my patch, nullified I add my:

for this patch.

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

I've tested gadget mode on DM365 without HW changes.

Queuing this patch for v3.8. Since the config options are removed there
is no use having code which refers to them. The patch has been tested on
DM644x and DM365 in both host and gadget mode (I will add this
information to commit text while committing). Without this patch .mode
seems to be defaulting to MUSB_UNDEFINED which I think is definitely wrong.

Thanks,
Sekhar

Thanks Felipe, I added your ack.

Constantine,

Patches touching arch/arm/* should be prefixed with 'ARM:' and those
touching mach-davinci should be prefixed with 'davinci:'. I added these
two while committing the patch this time. Please take care next time on.

Thanks,
Sekhar
