    ALSA: firewire-digi00x: add support for MIDI ports corresponding to isochronous packet streaming · 9fbfd38b
    Takashi Sakamoto authored
    This commit adds MIDI functionality to capture/playback MIDI messages
    from/to physical MIDI ports. These messages are transferred in isochronous
    packets.
    
    When no substreams request AMDTP streams to run, this driver starts the
    streams at current sampling rate. When other substreams start at different
    sampling rate, the streams are stopped temporarily, then start again at
    requested sampling rate. This operation can generate missing MIDI bytes,
    thus it's preferable to start PCM substreams at favorite sampling rate in
    advance.
    
    Digi 002/003 console also has a set of MIDI port for physical controls.
    These ports are added in later commits.
