[RESEND PATCH v3 0/2] ASoC/SoundWire: Intel: add sdw BE dai trigger

[Bard Liao]

For SOF IPC4, we need to set pipeline state in BE DAI trigger.
@Mark, resending this series in case it is lost in your mailbox.

v2:
 - Change "#if IS_ENABLED(CONFIG_SND_SOC_SOF_INTEL_SOUNDWIRE)" to
   "if (IS_ENABLED(CONFIG_SND_SOC_SOF_INTEL_SOUNDWIRE))"

v3:
 - Change the multi-line comment style in "soundwire: Intel: add trigger
   callback" patch and take Vinod's Ack.

  soundwire: Intel: add trigger callback
  ASoC: SOF: Intel: add trigger callback into sdw_callback

[RESEND PATCH v3 1/2] soundwire: Intel: add trigger callback

[Bard Liao]

When a pipeline is split into FE and BE parts, the BE pipeline may need to
be triggered separately in the BE trigger op. So add the trigger callback
in the link_res ops that will be invoked during BE DAI trigger.

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
