Hi Mark

I posted this patch-set 2weeks ago, and no response, no objection from community. Thus, I re-post these again.

These are Component level pcm_new/free v2. v1 pcm_new/free had breaked some platform, because it called "card" connected component callback. It should call "rtd" connected one's.

Special thanks to Arnaud who tested this v2 patch on his environment.

These patch-set adds rtd connected component list (= rtdcom) and replace current platform level pcm_new/free into component level pcm_new/free I don't know this naming (= rtdcom) sense is nice or not ;P I can replace it to more nicer naming if someone have nice sense.

New subject: [alsa-devel] [PATCH 1/3 v2][resend] ASoC: soc-core: add snd_soc_rtdcom_xxx()

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com

Current snd_soc_pcm_runtime has platform / codec pointers, and we could use these specific pointer. But these will be replaced to more generic "component" soon, and will need more generic method to get each connected component pointer from rtd.

This patch adds new snd_soc_rtdcom_xxx() to connect/disconnect component to rtd. It means same as previous "platform" / "codec" pointer style, but more generic. We can find necessary component pointer from rtd by using component driver name on snd_soc_rtdcom_lookup().

Here, the reason why it uses "driver name" is that "component name" was created by fmt_single_name() and difficult to use it from driver. Driver of course knows its "driver name", thus, using it is more easy.

New subject: [alsa-devel] Applied "ASoC: soc-core: add snd_soc_rtdcom_xxx()" to the asoc tree

The patch

ASoC: soc-core: add snd_soc_rtdcom_xxx()

has been applied to the asoc tree at

git://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

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

New subject: [alsa-devel] [PATCH 2/3 v2][resend] ASoC: use snd_soc_rtdcom_add() and convert to consistent operation

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com

Basically, current ALSA SoC framework is based on CPU/Codec/Platform, but its operation doesn't have consistent. Thus, source code was unreadable, and difficult to understand. This patch connects each component (= CPU/Codec/Platform) to rtd by using snd_soc_rtdcom_add(), and convert uneven operations to consistent operation.

New subject: [alsa-devel] [PATCH 3/3 v2][resend] ASoC: add Component level pcm_new/pcm_free v2

From: Kuninori Morimoto kuninori.morimoto.gx@renesas.com

In current ALSA SoC, Platform only has pcm_new/pcm_free feature, but it should be supported on Component level. This patch adds it.

The v1 was added commit 99b04f4c4051f7 ("ASoC: add Component level pcm_new/pcm_free") but it called all "card" connected component's pcm_new/free, it was wrong. This patch calls "rtd" connected component.

You posted three patch serieses threaded together with each other which made it look like it was intended to make the organization of a single big patch series clearer.

Yes. I'm sorry, it was not clear. From big picture (= replace platform to component) point of view, 3 step are needed, IMO. - 1) component tidyup/cleanup - 2) rtd component list - 3) replace platform to component

I posted these 3 patch-set in previous time. Because it can indicate 3 steps, and I wanted to know 2) and 3) opinion/review.

Now, 1) part is almost applied in your tree. It is independent from 2) and 3). This patch-set is 2) position. If 2) are accepted, I will post 3) patch-set.
