    Nice to see work done on a cellphone...

    Seeing all the GPIO name changes... would it be possible / make sense
    to make to device tree one day?

    What userspace do you run on the phone? Can it do calls?

    [I have N900 here, kernel is in pretty good state, and I have Mate desktop
    running with python application for calls, but...]

    Thanks (a pozdrav :-),
