Current DPCM support is used for "TDM-Split mode", "MIXer", "Sampling rate convert" for now. But, of course I have no objection if you can add new feature. > simple-audio-card,dai-link@2 { > cpu { > sound-dai=<&cpu1>; > } > } It looks FE, but is this for BE ? > Maybe add a property like "dpcm". I think property "dpcm" is very ALSA-SoC naming, DT guy don't like it (?). "simple-xxx-card" (1) or new node (2) can be acceptable ? I'm not sure... machine_drv { (1) compatible = "simple-xxx-card"; ... simple-audio-card,dai-link@2 { (2) dpcm-fe { sound-dai=<&cpu1>; ... Thank you for your help !!
