Pull request overview
This PR extends the Topology2 SDCA generic build targets to add 4-channel and 8-channel SoundWire DMIC (“SmartMic”) function topologies, and updates the Intel sdw-dmic-generic.conf platform fragment to make capture channel count/config/map configurable via new defines.
Changes:
- Add new
sof-sdca-mic-4ch-id4andsof-sdca-mic-8ch-id4topology build targets (viaNUM_DMICSoverrides). - Teach
sdw-dmic-generic.confto derive DMIC PCM channel count (and ch cfg/map) fromNUM_DMICSwhenSDW_DMIC_PCM_CHANNELS=0, and propagate this into DAI/widget/PCM caps formats.

Based on @shumingfan's test result, it seems it will duplicate ch0 to all other channels. I am trying to figure it out. |
