If you need to support a second codec on a dedicated bus, all you have
to do is set up a new snd_soc_dai_link. Read the documentation in
Documentation/sound/alsa/soc/ and see many of the good example in the
mainline kernel tree.

If your goal is to support a second codec in parallel to another one,
dynamix PCM (DPCM) is what you want to have a look at. It's there in the
kernel since 3.5, but AFAIK there's currently no user of it that can
serve as an example.
