ASoC.
+- cpu-dai: sti-asoc-platform subnode that describes properties for a CPU-DAI instance. +Required properties:
- dai-name: DAI name that describes the IP.
- dai-type: DAI functionality.
- "uni-player" for playback.
- "uni-reader" for capture.
It would be more idiomatic to do this with eithe ra commpatible string or a specifically named node.
+Optional properties:
- standby: standby mode activation deactivation. this mode is specific to
Uni player IP and allows to transmit bus clock and a pattern datawhile audio stream is stopped or paused.
I'm not entirely sure what the above means but it sounds like some software configuration rather than a property of the hardware? Or do some variants of the IP lack this functionality?
- auto-suspend-delay: runtime auto suspend delay (in ms) before deactivating
stanby mode. Equivalent to the DAPM mechanism but forCPU DAI.
DAPM works perfectly well for on SoC components, please use it.
