[PATCH v2 0/4] ASoC: remove unnecessary dai_link->platform

[PATCH v2 0/4] ASoC: remove unnecessary dai_link->platform

[Kuninori Morimoto]

Hi Mark

Current ASoC will ignore already connected component when binding Card.
This will happen mainly "CPU Component" is handled as "Platform Component",
which was needed before.

	static int snd_soc_rtd_add_component(...)
	{
		...
		for_each_rtd_components(rtd, i, comp) {
			/* already connected */
			if (comp == component)
				return 0;
		}
		...
	}

Some drivers are still using CPU or Dummy Component as Platform Component,
but these are no meaning or ignored.
This patch-set remove these.

v1 -> v2

	- remove the patch for simple-card
	- remove extra simple-card patch
	- add Acked-by for atmel patch

[PATCH v2 1/4] ASoC: fsl: remove unnecessary dai_link->platform

[Kuninori Morimoto]

dai_link->platform is no longer needed if CPU and Platform are
same Component. This patch removes unnecessary dai_link->platform.
Dummy Platform is also not necessary.

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

I think this patch is incorrect and should be reverted (I have received
a note from a SOF developer).
The link->cpus->dai_name is not necessarily "snd-soc-dummy", it is set
earlier:
if (strlen(pcm->dai_name)) {
	link->cpus->dai_name = devm_kstrdup(tplg->dev, pcm->dai_name,
					    GFP_KERNEL);
	if (!link->cpus->dai_name) {
		ret = -ENOMEM;
		goto err;
	}
}

We cannot be sure that it is the same component, in fact it is most like
not.

But sorry, I don't understand the point.
This patch removed dummy PLATFORM which is not necessary I think,
but you are talking about CPU.
Could you please explain more detail what is the problem ?


Thank you for your help !!

The patch removes the dummy platform with a justification that if the
CPU name and the platform name is identical, then the platform name does
not need to be set.

But in this case the CPU name and the platform name is _not_ identical,
they are different and we need to have the dummy platform on the FE side
unconditionally.

Re: [PATCH v2 4/4] ASoC: soc-topology.c: remove unnecessary dai_link->platform

Hi Peter

Thank you for your feedback

Oh, I didn't know that platform is needed on SOF.
Thank you for explaining detail, now I could understand your issue.

In my quick check, each SOF topology might overwrites link->platforms->name
and/or link->platforms->of_node...
I'm not 100% sure about SOF, but I looks strange for me...

I'm not sure which one is better idea, soc-topology.c has dummy platforms
and allow to be overwritten, or each topology alloc own platform if needed.

But I will post the fixup/revert patch for it. Could you please check it ?

Thank you for your help !!

Best regards
