Subject: c67x00 gadget support?

Hi Peter K,

Back in April 2007 you posted a patch series that included a prototype
of gadget support for the c67x00.

http://www.spinics.net/lists/linux-usb-devel/msg04766.html

The host-side stuff is all merged, just wondering what, if anything,
became of the gadget layer? It was some low level tweaks on
c67x00-drv.c but the majority was in c67x00-udc.[ch]

Thanks,

John

Yes, long time ago ;)

I'm afraid it never went much further. We ended up not using the gadget
side for that project, and haven't used the chip in any newer designs.

I do remember that we ended up having to patch the bios code running on
the device to get gadget mode running on port B. I'll see if I can find
the latest code somewhere if you're interested.
