+ Driver for transparent busses that don't need a real driver, but
+ where the bus controller is part of a PM domain, or under the control
+ of a functional clock, and thus relies on runtime PM for managing
+ this PM domain and/or clock.
+ An example of such a bus controller is the Renesas Bus State
+ Controller (BSC, sometimes called "LBSC within Bus Bridge", or
+ "External Bus Interface") as found on several Renesas ARM SoCs.
