Right, there's a very clear role for MFD in multiplexing the various functions of the device and dealing with any core behaviour it needs for bootstrapping or things like chip level suspend and resume. Dumping that into some random subsystem doesn't seem to make any sense, but doing things that fall outside that remit also don't seem clever.
