Hi All,
i have to support a 2nd Audio Codec with AC97 Interface on McBSP Port2. Processor: OMAP4460
If any one have any idea on how to go about this. Please let me know.
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.
HTH, Daniel
