USB Peripheral Controller
└─>AMD5536 UDC
In linux kernel since version 2.6.24 (release Date: 2008-01-24)  
The AMD5536 UDC is part of the AMD Geode CS5536, an x86 southbridge.
It is a USB Highspeed DMA capable USB device controller. Beside ep0
it provides 4 IN and 4 OUT endpoints (bulk or interrupt type).
The UDC port supports OTG operation, and may be used as a host port
if it's not being used to implement peripheral or OTG roles.

Say "y" to link the driver statically, or "m" to build a
dynamically linked module called "amd5536udc" and force all
gadget drivers to also be dynamically linked.
