    It's essentially what we're doing currently for the part of the system
    where we decide that everything is registered and we should run the
    actual probe functions so it'll help with that. Having a clock API we
    can actually use off-SoC will help with a lot of the remaining stuff.

    I *think* we'll still going to need to have the infrastructure to deal
    with running all the probes together, at least for a while, as the
    current code really assumes that it's got some of the card wide stuff
    around when all the devices get instantiated but I think if we were
    starting from fresh this would be fairly good. The only thing I can
    think might be an issue is n way dependencies, but those mostly shake
    out as being a dependency of the overall card on subdevices. I'd need
    to separate out the implementation issues from the assumptions to be
    100% clear if that was the case, though.
