[PATCH 00/19] ASoC: add soc-card

[PATCH 00/19] ASoC: add soc-card

[Kuninori Morimoto]

Hi Mark

Current ALSA SoC is handling snd_soc_card related operation,
but it is implmemented directly without using function/macro,
and at random place.

This patch-set creates new snd_soc_card_xxx() functions
which handles snd_soc_card related operation,
and implmement these at new soc-card.c.

[PATCH 01/19] ASoC: soc.h: convert bool to bit field for snd_soc_card

[Kuninori Morimoto]

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

[PATCH 02/19] ASoC: add soc-card.c

[Kuninori Morimoto]

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

Current ALSA SoC has some snd_soc_card_xxx() functions,
and card->xxx() callbacks.
But, it is implemented randomly at random place.

To collect all card related functions into one place,
this patch creats new soc-card.c.

Morimoto-san,

soc-card.h should be added where it is needed. For example, in this
patch, it should be included in soc-card.c and in the following
patches, it should be included in soc-core.c, soc-dapm.c etc where it
is needed.

Thanks,
Ranjani

OK, will fixup in v2

Thank you for your help !!

Hmm.... it seesm too many drivers are using snd_soc_card_xxx().
This means, I / this patch-set need to add too many #included <sound/soc-card.h>
line at too many files...

soc-component already did, but keeping it at soc.h is
more simple for some of them.
So, I want to keep it in v2

Thank you for your help !!

everywhere else I see a 1:1 mapping between variable and bitfield usage, 
not here, is this intentional?

This is a little bit confusable point for reviewing.
I will explain, so, please double check it.

This "soc_cleanup_card_resources()" will be called from
snd_soc_unbind_card() as "formal cleanup" or,
snd_soc_bind_card()   as "error handling" (D).

For "error handling" purpose, it needed to have "card_probed"
flags as parameter.

This "card->instantiated" will be set at (A) if
all probe functions were called (B) without error.
By this patch, "probed" is handled by "card".
Thus, it already has card->probed flag if
card has instantiated flag.

	static int snd_soc_bind_card(struct snd_soc_card *card)
	{
		...
	(B)	ret = snd_soc_card_probe(card);
		if (ret < 0)
			goto probe_end;
		...
	(B)	ret = snd_soc_card_late_probe(card);
		if (ret < 0)
			goto probe_end;
		...
	(A)	card->instantiated = 1;
		...
	probe_end:
		if (ret < 0)
	(D)		soc_cleanup_card_resources();
		...
	}

But indeed patch and log are confusable.
I will try to add such explanation at git-log area.

Thank you for your help !!

Best regards

Morimoto-san,

Why not move this check inside snd_soc_card_set_bias_level() and remove
the first parameter from the function?

Oh, yes, indeed.
We don't need "if (card)" check here.

But what does this "remove the first parameter from the function" mean ?
Do you mean "remove card" ?
Anyway, I will fixup [16/19] and [17/19] patches in v2

Thank you for your help !!
