Hello Morimoto-san, I want to know your opinion on enhancing simple-card in order to be able to create more flexible links. So far, simple-card allows the following cases: 1) normal sound all DAIs are detected as CPU - Codec (+optional platform). 2) DPCM sound 2a) all CPUs are detected CPU - <dummy_codec> [FE] 2b) all codecs are detected <dummy_cpu> - codec [BE] I will need to have a third case where I need to create a back end link like this: link->cpus->of_node = <&my_dai>; link->codecs->of_node = <&my_codec>; link->platforms->of_node = <&my_platform>; link->no_pcm = 1; Somehow, similar with qcom_snd_parse_of from sound/soc/qcom/common.c. Do you think it would be OK to create another file to handle this case in sound/soc/generic? Also, I would really like one day to really understand the role of cpu/platform/codec for a FE/BE. In the case of the FE: - cpu dai - platform - codec, here it makes sense to be dummy codec. In the case of BE: - cpu_dai - platform - codec, here it make sense to be reference to a real codec In the case of normal link: - cpu_dai, here it makes sense is a physical DAI - platform - codec, here it makes sense it is a physical codec. thanks, Daniel. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx https://mailman.alsa-project.org/mailman/listinfo/alsa-devel
