Enable support of pm_runtime on STM32 SAI driver to allow SAI power state monitoring. pm_runtime_put_autosuspend() is called from ASoC framework on pcm device close. The pmdown_time delay is available in runtime context, and may be set in SAI driver to take into account shutdown delay on playback. However, this shutdown delay is already handled in the DAPMs of the audio codec linked to SAI CPU DAI. So, the choice is made, not to support this delay on CPU DAI side.

Thanks!

All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted.
You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed.
If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.
Please add any relevant lists and maintainers to the CCs when replying to this mail.
Thanks, Mark
