As discussed in [1], ASoC core supports multi codec DAIs on a DAI link. However it does not do so for CPU DAIs. So, add support for multi CPU DAIs on a DAI Link by adding multi CPU DAI in Card instantiation, suspend and resume functions, PCM ops, stream handling functions and DAPM. [1]: https://www.spinics.net/lists/alsa-devel/msg71369.html changes in v4: - fix "rtd->num_codecs > 1" error in ASoC: Add Multi CPU DAI support - split "ASoC: pcm: check if cpu DAI support the given stream" from "ASoC: Add multiple CPU DAI support for PCM ops" - add helper "ASoC: Add dapm_add_valid_dai_widget helper" for "ASoC: Add multiple CPU DAI support in DAPM" Bard Liao (2): ASoC: return error if the function is not support multi cpu yet.
