[PATCH 00/24] ASoC: soc-component: collect component functions

[Kuninori Morimoto]

Hi Mark

We have soc-component.c now, but still many component related
functions are implemented many place.
This patch-set collect these into soc-component.c.

Kuninori Morimoto (24):
  ASoC: soc-component: add soc_component_pin() and share code
  ASoC: soc-component: move snd_soc_component_xxx_regmap() to soc-component
  ASoC: soc-component: move snd_soc_component_initialize() to soc-component.c
  ASoC: soc-component: add soc_component_err()
  ASoC: soc-component: add snd_soc_pcm_component_prepare()
  ASoC: soc-component: add snd_soc_pcm_component_hw_params()
  ASoC: soc-component: add snd_soc_pcm_component_hw_free()

[PATCH 01/24] ASoC: soc-component: add soc_component_pin() and share code

[Kuninori Morimoto]

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

soc-component has too many snd_soc_component_xxx_pin_xxx() functions.
The difference between these functions are used function name and
enable/disable.
This patch adds common soc_component_pin() and share code.

[PATCH 04/24] ASoC: soc-component: add soc_component_err()

[Kuninori Morimoto]

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

At soc-component.c, it is good idea to indicate error function and
its component name if there was error.
This patch adds soc_component_err() for it.

[PATCH 05/24] ASoC: soc-component: add snd_soc_pcm_component_prepare()

[Kuninori Morimoto]

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

We have 2 type of component functions
snd_soc_component_xxx()     is focusing to component itself,
snd_soc_pcm_component_xxx() is focusing to rtd related component.

Now we can update snd_soc_component_prepare() to
snd_soc_pcm_component_prepare(). This patch do it.

[PATCH 08/24] ASoC: soc-component: add snd_soc_pcm_component_trigger()

[Kuninori Morimoto]

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

We have 2 type of component functions
snd_soc_component_xxx()     is focusing to component itself,
snd_soc_pcm_component_xxx() is focusing to rtd related component.

Now we can update snd_soc_component_trigger() to
snd_soc_pcm_component_trigger(). This patch do it.

as much as possible to keep encapsulation.

[PATCH 22/24] ASoC: soc-component: merge soc-io.c into soc-component.c

[Kuninori Morimoto]

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

soc-io.c has snd_soc_component_xxx() functions for I/O.
We have soc-componennt.c for it.
Let's merge soc-io.c into soc-component.c

By this patch, original soc-io.c functions start to use
soc_component_err() when error case.

[PATCH 23/24] ASoC: soc-component: merge soc_pcm_trigger_start/stop()

[Kuninori Morimoto]

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

Now, soc_pcm_trigger_start/stop() are simple enough.
Let's merge these into soc_pcm_trigger().

Morimoto-san,
We should remove this. This will be a duplicate error message as
snd_soc_pcm_component_prepare() would already print the error before
returning.

Morimoto-san,

This is change is justified in one way but it also feels like maybe
because the functions are so specific to compr devices, it is best to
leave them here. Maybe others should also chime in.

Hmm.. I'm not sure.
Such kind of functions are already has been changed...
Let's ask to Maintainer.

Mark, what do you think ?

I don't think there's one right answer here.  I guess if we have to pick
we should do the same as is being done for PCM for compressed open but
either option is fine I think.

If you do decide to keep your changes to move all these functions to
soc-component.c, we need to include soc-component.h in soc-compress.c
isnt it?

Morimoto-san,

This seems slightly different from the original loop in
soc_compr_pointer() where we break as soon as the condition is true. So
should we return irrespective of the return value here?

I re-checked the patch.
The original code is soc_compr_xxx() and doing compress things.
I agree to keeping original code at original file.
I will remove these patched from v2 patch-set.

Thank you for your help !!

I re-re-checked.
I will drop this patch this time, but might post it again in the future.
Because we already have same/similar functon for DAI (= snd_soc_dai_compr_xxx()).

And I plan to add snd_soc_component_xxx() specific future, and
compr can use it.

Thank you for your help !!
