Takashi Sakamoto 6c5e1ac0e1 ALSA: firewire-motu: add support for Motu Traveler
This commit adds support for MOTU Traveler, launched in 2005, discontinued
quite before. As a result, transmission of PCM frame and MIDI messages is
available via ALSA PCM and RawMIDI/Sequencer interfaces.

This model supports sampling transmission frequency up to 192.0 kHz, and
AES/EBU on XLR interface and ADAT on optical interface. Unlike
Motu 828MkII, Windows driver can switch fetching mode for DSP, like
mute/unmute feature.

Although this commit enables high sampling transmission frequency, actual
sound from this model is not good. As long as I tested, it's silence at
176.4 kHz, and it includes hissing noise at 192.0 kHz. In my opinion, as I
reported at 3526ce7f9ba7 ('ALSA: firewire-motu: add MOTU specific protocol
layer'), timestamping on source packet header (SPH) may not still be good
for this model as well.
