OK so Felipe can merge these smallish patches to musb, fine...

The other (DMA) stuff needs to be merged together with the rest
of the DMA40 series, so here basically Felipe needs an indication
if he can ACK it so I merge it through ARM SoC without colissions
and it sounds like we can make the assumption that this will work.
