Yes it does.

Some minor things:
- please use to_udc() in start then
- would it make sense to use platform_get_drvdata() in
   lpc32xx_udc_shutdown() ?
- could you please remove struct usb_endpoint_descriptor from struct
   lpc32xx_ep? It has been removed a while back from other drivers.

Your proc_udc_show() makes me sad. Felipe, didn't we want something
like this in udc-core?
