The upstream supplies to which the USB controller on SH would attach are not described in SH DT yet, and they are always on, so I don't think we need to describe the controller in SH DT yet, do we ?

Indeed, not necessarily, describing it would be required for power control and eventually to describe usb hubs as subnodes if they also need reset and power control.
