Subject: [PATCH RFC] ASoC: amlogic: do not use dpcm_playback/capture flags
Date: Tue, 14 May 2024 16:30:46 +0200

dpcm_playback/capture flags are being deprecated in ASoC.
Use playback/capture_only flags instead

Following Kuninori's series, dpcm_playback/capture will be ignored.
However, properly disabling stream direction is important for Amlogic
audio drivers.

I'm not too sure how this should be applied to avoid breaking bisect,
before or after Kuninori's series. Maybe it should be merged into it ?

Any suggestion Kuninori ?
