[PATCH 0/7][RFC] ASoC: modern style CPU

[PATCH 0/7][RFC] ASoC: modern style CPU

[Kuninori Morimoto]

Hi Mark

These are RFC of modern style CPU support.

modern style dai_link needs CPU/Codec/Platform array and its size,
but it will be very ugly code. To avoid it, 3) adds macro.

4) - 7) are sample code for switching to modern style dai_link.
4), 5) are good sample for single CPU/Codec/Platform.
6), 7) are good sample for multi Codec.

Almost all sound cards will get similar patch.
I think these can work, but I can't test these.
So, it is very useful if someone can test these.
If these are all OK (= test/review), I can post patch-set
for all sound cards.

	1) ASoC: soc-core: use snd_soc_dai_link_component for CPU
	2) ASoC: simple-card: support snd_soc_dai_link_component style for cpu
	3) ASoC: soc.h: add sound dai_link connection macro
	4) ASoC: samsung: smdk_wm8580: use modern dai_link style
	5) ASoC: samsung: smdk_wm8994: use modern dai_link style
	6) ASoC: mediatek: mt8173-rt5650-rt5676: use modern dai_link style
	7) ASoC: mediatek: mt8173-rt5650-rt5514: use modern dai_link style

Thank you for your help !!

Best regards

[PATCH 1/7][RFC] ASoC: soc-core: use snd_soc_dai_link_component for CPU

[Kuninori Morimoto]

current ALSA SoC is starting to support modern style dai_linke
(= struct snd_soc_dai_link_component) which is mainly used for
multipul DAI/component connection.
Now Codec has full multi-codec support, Platform is using modern
style but still for single Platform.
Only CPU is not yet supporting modern style yet.
If we could support it for CPU, we can switch to modern style
dai_link on all CPU/Codec/Platform, and remove legacy style
from ALSA SoC.

Multi-CPU will be supported in the future.
This patch is initial support for modern style for CPU

[PATCH 2/7][RFC] ASoC: simple-card: support snd_soc_dai_link_component style for cpu

[Kuninori Morimoto]

ASoC supports modern style dai_link (= snd_soc_dai_link_component) for
CPU. legacy style dai_link (= cpu_dai_name, cpu_name, cpu_of_node) are
no longer needed.
This patch switches to modern style.

[PATCH 3/7][RFC] ASoC: soc.h: add sound dai_link connection macro

[Kuninori Morimoto]

Modern style dai_link requests CPU/Codec/Platform component
pointer array and its size, but it will be very verbose code.
To avoid such scene, this patch adds dai_link connection macro.

This looks basically fine to me, hopefully someone will be able to help

I know you are already working for it for Intel

	https://github.com/plbossart/sound/commits/fix/codec-legacy-dai

and, it will be conflict to my posted patch style.

	https://patchwork.kernel.org/patch/10888741/
	https://patchwork.kernel.org/patch/10888745/

So, I can avoid to posting patch for Intel,
then, you need to update it again for modern style CPU.
Or, I can update Intel by using above macro.
What is your opinion ?

Thank you for your help !!

I must admit I didn't look at the new style. With all due respect I am 
not sold, it's becoming a lot less intuitive and readable, e.g.:

+SND_SOC_DAI_LINK_CCP(aif1,
+	SND_SOC_DAI_LINK(SDL_CPU("samsung-i2s.0")),
+	SND_SOC_DAI_LINK(SDL_CODEC("wm8994-codec", "wm8994-aif1")),
+	SND_SOC_DAI_LINK(SDL_PLATFORM("samsung-i2s.0")));
+
+SND_SOC_DAI_LINK_CCP(fifo_tx,
+	SND_SOC_DAI_LINK(SDL_CPU("samsung-i2s-sec")),
+	SND_SOC_DAI_LINK(SDL_CODEC("wm8994-codec", "wm8994-aif1")),
+	SND_SOC_DAI_LINK(SDL_PLATFORM("samsung-i2s-sec")));
+
  static struct snd_soc_dai_link smdk_dai[] = {
  	{ /* Primary DAI i/f */
  		.name = "WM8994 AIF1",
  		.stream_name = "Pri_Dai",
-		.cpu_dai_name = "samsung-i2s.0",
-		.codec_dai_name = "wm8994-aif1",
-		.platform_name = "samsung-i2s.0",
-		.codec_name = "wm8994-codec",
  		.init = smdk_wm8994_init_paiftx,
  		.dai_fmt = SND_SOC_DAIFMT_I2S | SND_SOC_DAIFMT_NB_NF |
  			SND_SOC_DAIFMT_CBM_CFM,
  		.ops = &smdk_ops,
+		SND_SOC_LINK_CCP(aif1),

is this really the new direction?
Even the acronyms are not simple, it took me 15mn to figure out that CCP 
stood for CPU/Codec/Platform and I couldn't figure out what SDL means. 
The multiple repetitions of SND_SOC_DAI_LINK is also misleading, it's 
just a property of the *same* dailink that you handle.

I am even more nervous since we have a need to explicitly some cpu and 
codec dai names depending on quirks, with the additional abstraction 
it'll become plain unreadable - or we need new helpers.

The reason of "CCP" (= CPU/CODEC/PLATFORM) was to avoid long naming.
and SDL is acronyms of "Snd soc Dai Link". but yes, it is un-understandable.
It should be more understandable (and possibly short) naming.

> The multiple repetitions of SND_SOC_DAI_LINK is also

it is needed to handle both single/multi CPU/Codec/Platform.
But yes, it has naming issue.

Hmm, OK.
I will reconsider about macro.
I'm happy if you can review it again.

I think you're right to want a shorter name but Pierre's probably right
that that particular name isn't the best...  I'm thinking it might be
good to look at the fully expanded definitions and then work back from
there, or perhaps just stick with them for a while (since the compact
forms are hopefully not a requirement for legibility, even if they are a
useful improvement).

These are proposal of modern style macro v2.
