[alsa-devel] [PATCH 00/16] ASoC: remove DAI suspend/resume
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.

There is no big difference at implementation for .suspend/.resume between DAI driver and Component driver. But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can switch all DAI driver .suspend/.resume to Component driver, we can remove verbose code from ALSA SoC.
Driver is getting its private data via dai->dev. But dai->dev and component->dev are same dev, thus, we can convert these. For same reason, we can convert dai->active to component->active if necessary.
This patch moves DAI driver .suspend/.resume to Component driver

There is no big difference at implementation for .suspend/.resume between DAI driver and Component driver. But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can switch all DAI driver .suspend/.resume to Component driver, we can remove verbose code from ALSA SoC.
Driver is getting its private data via dai->dev. But dai->dev and component->dev are same dev, thus, we can convert these. For same reason, we can convert dai->active to component->active if necessary.
This patch moves DAI driver .suspend/.resume to Component driver

There is no big difference at implementation for .suspend/.resume between DAI driver and Component driver. But because some driver is using DAI version, thus ALSA SoC needs to keep supporting it, hence, framework becoming verbose. If we can switch all DAI driver .suspend/.resume to Component driver, we can remove verbose code from ALSA SoC.

Historically, CPU and Codec were implemented different, but now it is merged as Component. ALSA SoC is supporting suspend/resume at DAI and Component level. The method is like below.
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) was Codec special operation. Because CPU and Codec were merged into Component, CPU has 3 chance to suspend/resume(= 1/2/3), but Codec has 1 chance to suspend/resume(= 2).
Here, 1) 2) are caring bus-control, but no driver which is supporting suspend/resume has bus-control. This means 3) is never used.
Here, used parameter for suspend/resume component->dev and dai->dev are same pointer. For these reason, we can merge DAI and Component suspend/resume. One note is that we should use 2), because it is caring BIAS level.
This patch removes 1) and 3).

Hi Mark
From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com
Now, snd_soc_dai_driver::bus_control is used for how to resume. But, no driver which has bus_control has DAI driver suspend/resume support. This patch removes pointless bus_control from ALSA SoC.

I noticed that this [17/16] patch (Yes, It is strange) has compile warning. I will repost this patch later. Please ignore it. This means, please care [01/16] - [16/16] only.
Thank you for your help !! Best regards --- Kuninori Morimoto

Perhaps that 17/16 thing was trying to tell you something :)
