    I think there is value in having everything under drivers/... With
    drivers/<bus>, we can already cover most of the architecture-specific
    bits. Maybe just a few more bus types are needed - e.g. many "system on
    a chip" design families have some tiny little bus and all the devices
    there are rather unique and may have a lot of shared resources.

    On the other hand, drivers/<function> makes sense for generic drivers
    (e.g. drivers/char/mem.c) and those supporting many buses. So perhaps a
    chipset that is used on many platforms should be split into the bus
    interfaces in drivers/<bus> and the portable part in drivers/<fn> ?

    This would probably require include/drivers or such, to avoid
    cluttering include/linux with tons of additional "internal" files.
    Also, drivers/<bus> should probably be reserved for drivers for the bus
    itself, with the device drivers in drivers/<bus>/<fn>, or drivers/pci
    would look a little nasty ;-)

    Furthermore, if a driver starts is existence in drivers/<bus>, and then
    turns out to be useful on other buses too, it would have to be split.
    This would be a departure from the current implicit assumption that you
    pick "The Right Place" once and forever. It would also make it harder
    to port somebody else's driver to a second bus. But it would limit code

    Does this sound reasonable ?
