You can find a driver for this Synopsys DWC OTG controller in our 
linux-2.6-denx repository:

http://git.denx.de/?p=linux-2.6-denx.git;a=tree;f=drivers/usb/gadget/dwc_otg;h=526d515e4764a0c92cebbf909c245d6aec7e198c;hb=HEAD

But please note that this driver is currently not in shape for mainline 
inclusion. It's working though, so it should help you while writing a new, 
clean driver.

Best regards,
Stefan
