[alsa-devel] [PATCH v4 0/8] ASoC: core: Add support for DAI multicodec

[Benoit Cousson]

Hi Lars, Mark and Liam,

Sorry for the delay. Here is the fourth version of the multicodec series.

I had to split it in smaller chunks since the previous patch was exceeding the 
size limit of the ML :-(

I think (and hope) I did address all the v3 comments from Lars.

I did not address the codec to codec link in multicodec case as suggested
by Lars.

There is still an open point about enforcing the number of channels for the
CPU dai in case the TDM slots are set for the CODEC dais.
I guess this point could be addressed later.

Please note that I have a very simple setup based on BBB to check if the series
is working, so it will be good to test it on various platforms to ensure
this is not generating any regression.

The series is based on asoc/for-next (v3.16-rc1).

Test and comments are welcome.

Thanks,
Benoit
