[alsa-devel] [PATCH 11/13] bebob: Add support for Terratec PHASE series

Sat Nov 23 07:09:23 CET 2013
This commit allows this driver to support all of models which Terratec produced
with BeBoB chipset. They are:
- PHASE 24 FW
- PHASE X24 FW
- PHASE 88 Rack FW
This commit adds Terratec specific operations, quirks for three functionalities.
1. Switching source of clock
2. Change sampling frequency
3. Check clock synchronization
The driver uses these functionalities with AV/C vendor specific commands and
AV/C Audio Subunit commands.
