We add a DAI for the link to the baseband. This will become visible to the application layer - audio should be started from the application layer using an application such as this: http://opensource.wolfsonmicro.com/~gg/bluetooth-pcm/bluetooth_pcm.c which starts up audio as for CPU based playback and record up to the point where data is streamed. Due to non-availability of baseband simulation hardware we reuse the configuration for the CPU link with the CODEC acting as clock master, allowing signals to be observed with a scope. A more standard system would have separate configuration for the baseband with its own ops structure and operations. Normally the baseband would be clock master as the baseband audio will be synchronised to the external telephony network.
