Unrelated accidental change here though. :)

Did I miss a matching series actually implementing the driver? I'd need
to test the latest version to determine how to update the Parallella
device tree - I assume that USB0 is in dr_mode="host", but with the
previous patchsets I was unable to verify. CC'ing Ola.
