RT722 is a multi-function codec which supports headset, amp, and dmic functions. Each function provides a DAI which can be used in different dailinks. The RT711 supports up to 3 SoundWire lanes, but that should not have any impact in the machine driver: the lanes are allocated and controlled by the manager and bandwidth allocation algorithm.
