    Could you expand on how you see that being implemented, please? It
    doesn't feel entirely comfortable to me - providing a bus for the chip
    seems more direct and the platform bus not what I'd think of using for
    something hanging off another bus - but I think I'm just not visualising
    what you're thinking of properly.

    The multi-function device support does feel like it could be a good fit.
    I'd seen it discussed sometime last year but don't recall seeing
    anything for quite a while. Like Ben said, any pointers to current work
    would be appreciated.

    It's probably worth mentioning that in addition to what is in the
    current patch series these chips all also provide an audio codec which
    requires a reasonably substantial driver for full support.
