Right. I see this as glue for the most part. You could argue it's a small
pinctrl, but this doesn't route external pins, it's more to connect pins
internally to the IP block and it's sub-device parts (qup, uart, etc).

The intent of the gsbi driver is merely to provide/configure the single mux
setting for the devices that share those 4 IO lines. I don't see this as a full
blown bus.
