Hi Mark Now, ALSA SoC calls 2 type of suspend/resume suspend/resume for Component suspend/resume for DAI When ALSA SoC calls suspend/resume, its orders are 1) Suspend/Resume all CPU DAI if bus-control was 0 2) Suspend/Resume all Component 3) Suspend/Resume all CPU DAI if bus-control was 1 Historically 2)'s "Component" was "Codec", before. In total, CPU has 3 chance to suspend/resume(= 1/2/3), but Codec has 1 chance to suspend/resume(= 2). And now, no driver which is supporting suspend/resume has bus-control. This means 3) is never used. Almost all drivers which is using DAI suspend/resume can simply switch to Component suspend/resume. Few drivers want to use/keep DAI, but, we can call all DAI from Component by using this if needed for_each_component_dais() These patches switches all DAI's suspend/resume to Component one, and removes it.
