Re: [alsa-devel] [PATCH v4 08/13] ASoC: Add SoundWire stream programming interface

+/**

• • snd_soc_dai_set_sdw_stream() - Configures a DAI for SDW stream operation
• • @dai: DAI
• • @stream: STREAM
• • @direction: Stream direction(Playback/Capture)
• • SoundWire subsystem doesn't have a notion of direction and we reuse
• • the ASoC stream direction to configure sink/source ports.
• • Playback maps to source on the TX and sink on Rx. Vice-versa for Capture.

this is just confusing...

This should be something like "use Playback for source ports and Capture for sink ports".
