[PATCH 3/7] ASoC: Intel: sof_sdw: Add rt722 support

Peter Ujfalusi
2023-11-27T13:35:52Z

From: Chao Song <chao.song@linux.intel.com>

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.
