In linux kernel since version 4.1 (release Date: 2015-06-21)
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.
