Though outside this topic, please see latest code from samsung GIT. I already share wm8580 dai with I2S primary_fifo dai as well as secondary_fifo dai. I implemented temporary workaround to share dais(luckily codec_dai wasn't used in a way to make it impossible, though cpu_dai still can't be shared). Also, there is some reason I didn't point to our repository:- the code is not meant for mainline. It's just a 'workaround' for urgent requirement. Now, I wud like to get back to getting suggestions about how to approach the solution from mainline's POV rather than discussing Samsung's internal code. _______________________________________________ Alsa-devel mailing list Alsa-devel@xxxxxxxxxxxxxxxx http://mailman.alsa-project.org/mailman/listinfo/alsa-devel
