The orginal code does not cover the case that one DAI such as codec may be shared between other two DAIs(CPU).
Can you give me an example of how this can occur?
Pls check the following case used in mx28evk. static struct snd_soc_dai_link mxs_sgtl5000_dai[] = { { .name = "HiFi Tx", .stream_name = "HiFi Playback", .codec_dai_name = "sgtl5000", .codec_name = "sgtl5000.0-000a", .cpu_dai_name = "mxs-saif.0", .platform_name = "mxs-pcm-audio.0", .ops = &mxs_sgtl5000_hifi_ops, }, { .name = "HiFi Rx", .stream_name = "HiFi Capture", .codec_dai_name = "sgtl5000", .codec_name = "sgtl5000.0-000a", .cpu_dai_name = "mxs-saif.1", .platform_name = "mxs-pcm-audio.1", .ops = &mxs_sgtl5000_hifi_ops, }, }; You can also refer to: http://thread.gmane.org/gmane.linux.ports.arm.kernel/129789/focus=129839
Timur, iirc your driver has some special symmetry requirement (maybe something todo with having 2 DAIs) ?
I assume this is OK for you too ?

Can you apply this?
