Hi Mark, Pierre-Louis, Jerome
Cc each ASoC driver maintainer

As we discussed in [1], we don't need to use dpcm_playback/capture flag,
so we remove it. But we have been using it for 10 years, some driver might
get damage. The most likely case is that the device/driver can use both
playback/capture, but have only one flag, and not using xxx_only flag.
[1/3] patch indicates warning in such case.

And because of its history, DPCM has been checking CPU side only. But it should
check Codec side too same as non-DPCM. Some device/driver has been bypassed
this check. It should be error. [2/3] patch indicates warning in such case.

Because dpcm_xxx flag is no longer used by [1/3] patch, 
snd_soc_dai_link_set_capabilities() is no longer needed. [3/3] patch remove it.

These adds grace time for DPCM cleanup.
I'm not sure when dpcm_xxx will be removed, and Codec check bypass will be error,
but maybe v6.11 or v6.12 ?
Please check each driver by that time.

v1 -> v2
	- tidyup Codec check warning output condition

Kuninori Morimoto (3):
  ASoC: soc-pcm: Indicate warning if dpcm_playback/capture were used for availability limition
  ASoC: soc-pcm: Indicate warning if CPU / Codec availability mismatch
  ASoC: remove snd_soc_dai_link_set_capabilities()
