None at all. That sounds good to me.

To be able to use DSPS-based controllers with device-tree descriptions of the USB topology, we need to associate the glue device's device-tree node with the child controller device. Note that this can also be used to eventually let USB core manage generic phys. Also note that the other glue drivers will require similar changes to be able to describe their buses in DT.
