    The MFDs I've looked at (which admittedly might not be that many) all
    have the top-level chip described in device tree, but not all the
    component sub-devices, since they're all a static part of the top-level
    chip. Instead, the top-level MFD instantiates all the sub-devices
    itself. I'm curious why this MFD device works differently - do many work
    like this?
