    The driver creates a fake "ibmebus" device so all ibmebus based devices
    have
    a common parent device -- the vio bus does the same.

    What do you think about linking this device to the device tree "/" node?
    All
    ibmebus-based devices are linked to dt nodes residing directly beneath
    "/",
    so the mapping would fit.

    Cheers,
    Joachim
