Following DWC USB example, I think wrappers are discouraged. The
integration of a block is together with that block an entire device.
Integration is not something separate, at least usually. If it is,
author should provide some arguments in terms of hardware. The arguments
of driver are unconvincing.

And to prove this is same device (integration = block), the MMIO is the
same.
