[PATCH v3 0/2] ASoC/SoundWire: Intel: add sdw BE dai trigger
For SOF IPC4, we need to set pipeline state in BE DAI trigger. @Vinod, Could you ack if the soundwire patch looks good to you? And we can go through the ASoC tree since the change is mainly on ASoC.
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.

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.
