ALSA: firewire-motu: add support for MOTU UltraLite
UltraLite was shipped in 2005 by MOTU, and already discontinued. This
model consists of below ICs:
- Texus Instruments TSB41AB2 for physical layer of IEEE 1394 bus
- Xilinx Spartan XC35S200 for link layer of IEEE 1394 bus, protocol layer
and signal processing
This commit adds support for this model. Like the other MOTU models,
ALSA firewire MOTU driver fails to drive the device for stable sampling
clock and generate noisy sound.
