    Actually... no, what you done is not GNSS subsystem. It is generic
    subsystem for a link + some controls, typically for power.

    Yes, that setup is common for GPS receivers, but it is there also for
    modems (droid 4: usb + gpios) and bluetooth dongles (n900: serial +
    gpios).

    Best regards,
