    Copyright (C) 1998,1999,2000 Michael Hunold <michael@mihu.de>

    The tea6415c is a bus controlled video-matrix-switch
    with 8 inputs and 6 outputs.
    It is cascadable, i.e. it can be found at the addresses
    0x86 and 0x06 on the i2c-bus.

   8 inputs and 6 outputs, these aren't enumerated in any way. because
   I don't want to say "connect input pin 20 to output pin 17", I define
   a "virtual" pin-order. */
