Yes but one of the problems I see that we have specific ordering on the DAI ops between various components, is that a specific requirement? > About cleanup rtd->cpu_dai / rtd->codec_dai topic, > I don't know we can do it at this point. > But, I'm happy to think about it. > I'm thinking like this > 1st step: add Multi CPU support Okay we will send the patches for this by next week or so... > 2nd step: Share code between CPU/Codec DAI And then discuss how to make it common > 3rd step: think about No-Categorized DAI (if possible) > Because many drivers are directly using rtd->cpu_dai, rtd->codec_dai We should fix that part while at it. I guess drivers needs own dai, possibly for name or some data, so if they have helpers for that, we should be able to remove those.. -- ~Vinod _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
