This commit allows this driver to support all of models which Focusrite produces with DM1000/BeBoB. They are: - Saffire - Saffire LE - SaffirePro 10 I/O - SaffirePro 26 I/O This commit adds Focusrite specific operations: 1. Get source of clock 2. Get/Set sampling frequency 3. Get metering information The driver uses these functionalities to read/write specific address by async transaction.
