- Does trigger is needed when CPU-DAI is master on bus?
Otherwise how to inform HDMI that I2S bus is no more clocked? I'm not sure that mute is sufficient for all hardwares... For instance for my hardware CTS parameter is hardware computed based on I2S L/R clock.
I'd expect us to be always calling trigger - is there some debate on this? Obviously since it's called in atomic context it can be difficult to use but we should be notifying.
If the question is only on trigger being non atomic, we certainly allow that now, we can specify that by having dailinks's nonatomic flag as true
