    [media] ati_remote: add support for Medion X10 Digitainer remote · 9d454d48

    Add support for another Medion X10 remote. This was apparently
    originally used with the Medion Digitainer box, but is now sold
    separately without any Digitainer labeling.
    
    A peculiarity of this remote is a scrollwheel in place of up/down
    buttons. Each direction is mapped to 8 different scancodes, each
    corresponding to 1..8 notches, allowing multiple notches to the same
    direction to be transmitted in a single scancode. The driver transforms
    the multi-notch scancodes to multiple events of the single-notch
    scancode.
    (0x70..0x77 = 1..8 notches down, 0x78..0x7f = 1..8 notches up)
    
    Since the scrollwheel scancodes are the same that are used for mouse on
    some other X10 (ati_remote) remotes, the driver will now check whether
    the active keymap has a keycode defined for the single-notch scancode
    when a mouse/scrollwheel scancode (0x70..0x7f) is received. If set,
    scrollwheel is assumed, otherwise mouse is assumed.
    
    This remote ships with a different receiver than the already supported
    Medion X10 remote, but they share the same USB ID. The only difference
    in the USB descriptors is that the Digitainer receiver has the Remote
    Wakeup bit set in bmAttributes of the Configuration Descriptor.
    Therefore that is used to select the default keymap.
    
    Thanks to Stephan Raue from OpenELEC (www.openelec.tv) for providing me
    both a Medion X10 Digitainer remote+receiver and an already supported
    Medion X10 remote+receiver. Thanks to Martin Beyss for providing some
    useful information about the remote (including the "Digitainer" name).
    This patch has been tested by both of them and myself.
