I have been wondering why DPCM needs special flag (= dpcm_playback/capture)
to use it. Below is the history why it was added to ASoC.
...
Because of these history, this dpcm_xxx is unneeded flag today. But because
we have been used it for 10 years since (B), it may have been used
differently. For example some DAI available both playback/capture, but it
set dpcm_playback flag only, in this case dpcm_xxx flag is used as
availability limitation. We can use playback_only flag instead in this
case, but it is very difficult to find such DAI today.
Let's add grace time to remove dpcm_playback/capture flag.
This patch don't use dpcm_xxx flag anymore, and indicates warning to use
xxx_only flag if both playback/capture were available but using only
one of dpcm_xxx flag, and not using xxx_only flag.
This is a cleanup/refactoring preparation patch, I can see no reason why
it would be considered for stable.
Dropped, thanks!
