ASoC: component: Add sync_stop PCM ops

2019-11-22T13:38:01+00:00

Add the support of the new PCM sync_stop ops in ASoC component.
It's optional and can be NULL unless you need the sync operation.

ASoC: soc-component: tidyup snd_soc_pcm_component_new/free() parameter

2019-11-19T18:22:40+00:00

This patch uses rtd instead of pcm at snd_soc_pcm_component_new/free()
parameter.
This is prepare for dai_link remove bug fix on topology.

ASoC: soc-component: remove snd_pcm_ops from component driver

2019-10-08T12:51:02+00:00

No driver is using snd_pcm_ops on component driver.
This patch removes it.

ASoC: soc-core: add new pcm_construct/pcm_destruct

2019-10-08T12:40:22+00:00

Current snd_soc_component_driver has pcm_new/pcm_free, but,
it doesn't have "component" at parameter.
Thus, each callback can't know it is called for which component.
Each callback currently is getting "component" by using
snd_soc_rtdcom_lookup() with driver name.

It works today, but, will not work in the future if we support multi
CPU/Codec/Platform, because 1 rtd might have multiple same driver
name component.

To solve this issue, each callback need to be called with component.
This patch adds new pcm_construct/pcm_destruct with "component"
parameter.

ASoC: soc-core: merge snd_pcm_ops member to component driver

2019-10-08T12:39:53+00:00

Current snd_soc_component_driver has snd_pcm_ops, and each driver can
have callback via it (1).
But, it is mainly created for ALSA, thus, it doesn't have "component"
as parameter for ALSA SoC (1)(2).
Thus, each callback can't know it is called for which component.
Thus, each callback currently is getting "component" by using
snd_soc_rtdcom_lookup() with driver name (3).

	--- ALSA SoC  ---
	...
	if (component->driver->ops &&
	    component->driver->ops->open)
(1)		return component->driver->ops->open(substream);
	...

	--- driver ---
(2)	static int xxx_open(struct snd_pcm_substream *substream)
	{
		struct snd_soc_pcm_runtime *rtd = substream->private_data;
(3)		struct snd_soc_component *component = snd_soc_rtdcom_lookup(..);
		...
	}

It works today, but, will not work in the future if we support multi
CPU/Codec/Platform, because 1 rtd might have multiple components which
have same driver name.

To solve this issue, each callback needs to be called with component.
We already have many component driver callback.
This patch copies each snd_pcm_ops member under component driver,
and having "component" as parameter.

	--- ALSA SoC  ---
	...
	if (component->driver->open)
=>		return component->driver->open(component, substream);
	...

	--- driver ---
=>	static int xxx_open(struct snd_soc_component *component,
			    struct snd_pcm_substream *substream)
	{
		...
	}

*Note*

Only Intel skl-pcm has .get_time_info implementation, but ALSA SoC
framework doesn't call it so far.
To keep its implementation, this patch keeps .get_time_info,
but it is still not called.
Intel guy need to support it in the future.

ASoC: soc-component.h: remove GPL explanation from header

soc-component.h already has SPDX License, thus, GPL explanation
is not needed. This patch removes it.

ASoC: soc-component: add snd_soc_pcm_component_pcm_free()

2019-08-05T15:27:16+00:00

Current ALSA SoC is directly using component->driver->xxx,
thus, the code nested deeply, and it makes code difficult to read,
and is not good for encapsulation.

We want to implement component related function at soc-component.c,
but, some of them need to care whole snd_soc_pcm_runtime (= rtd)
connected component.

Let's call component related function which need to care with
for_each_rtdcom() loop as snd_soc_pcm_component_xxx().
This patch adds new snd_soc_pcm_component_pcm_free() and use it.
