[alsa-devel] [PATCH RFC v3 0/4] ASoC: Add Multi CPU DAI support

[Bard liao]

As discussed in [1], ASoC core supports multi codec DAIs
on a DAI link. However it does not do so for CPU DAIs.

So, add support for multi CPU DAIs on a DAI Link by adding
multi CPU DAI in Card instantiation, suspend and resume
functions, PCM ops, stream handling functions and DAPM.

[1]: https://www.spinics.net/lists/alsa-devel/msg71369.html

changes in v3:
 - Return error if the function doesn't support multi cpu instead of
   just showing a warning message.
 - Revert changes for FE dai and compress device since we don't support
   multi cpu for FE dai and compress device yet.

Bard liao (1):
  ASoC: return error if the function is not support multi cpu yet.

Shreyas NC (3):
  ASoC: Add initial support for multiple CPU DAIs
  ASoC: Add multiple CPU DAI support for PCM ops
  ASoC: Add multiple CPU DAI support in DAPM
