Why ?

A device needs to vote on its own interconnect and power-domains on any 
bus. A sub-device of another device may wish to ramp a clock for 
whatever reason.

There is no "master" device in this block of devices - save perhaps for 
the CSID mux / wrappers on some of these parts.

We have shared resources like camera noc, system noc and external clocks.

Please include power-domains and interconnects.
