[alsa-devel] [PATCH 10/13] bebob: Add support for Focusrite Saffire/SaffirePro series

Sat Nov 23 07:09:22 CET 2013
This commit allows this driver to support all of models which Focusrite
produces with BeBoB chipset. They are:
- Saffire
- Saffire LE
- SaffirePro 10
- SaffirePro26
This commit adds Focusrite specific operations, quirks for its four
functionalities.
1. Switching source of clock
2. Change sampling frequency
3. Check clock synchronization
4. Get metering information
The driver uses these functionalities to read/write specific address by async
transaction.
