[PATCH 0/x][RFC] ASoC: replace codec/platform to component

[PATCH 0/x][RFC] ASoC: replace codec/platform to component

[Kuninori Morimoto]

Hi Mark

Finally, all prepare patch-set were accepted.
These are [RFC] of codec/platform replace to component patch-set.
It will be almost 200 patches in total.
Thus, to avoid patch bomb (in case of rejection),
I pickuped few patches and post these as [RFC].

Main is replacing codec/platform to component

	xxx_codec_xxx()    -> xxx_component_xxx()
	xxx_platform_xxx() -> xxx_component_xxx()

Note1 is that it is using devm_ version register function,
and removed unregister from .remove
(sometimes, removes .remove function itself)

	- snd_soc_register_xxx()
	+ devm_snd_soc_register_component()
	...
	- snd_soc_unregister_xxx()

Note2 is that rtd->platform will be removed, thus it will be replaced
to snd_soc_rtdcom_lookup() with driver name

	- rtd->platform
	+ snd_soc_rtdcom_lookup(rtd, DRV_NAME)

Note3 is that codec driver needs to have some flags which is needed for Codec

	-static const struct snd_soc_codec_driver xxx_codec;
	+static const struct snd_soc_component_driver xxx_codec = {
	+	.idle_bias_on		= 1,
	+	.pmdown_time		= 1,
	+	.endianness		= 1,
	+	.non_legacy_dai_naming	= 1,
	+};

here,
 .idle_bias_on was originally .idle_bias_off
 .pmdown_time  was originally .ignore_pmdown_time
 .endianness            is needed for Codec endianness check
 .non_legacy_dai_naming is needed for Codec DAI name matching

Note4 is that some driver is controlling CPU/Platform in one driver
as 2 component. Now we can merge these into one component.

	- snd_soc_register_platform(xxx)  // for Platform
	- snd_soc_register_component(xxx) // for CPU
	+ snd_soc_register_component(xxx) // for CPU/Platform

Note4 is that [1/x] patch which removes (!rtd->platform) check from
soc-core is needed for all platforms.
This check is no longer needed for component version.

If these [RFC] were OK, I will post all replacement patch-set.
I think good timing to posting is around next -rc1 or merge-window

About removing all unneeded codec/platform patch-set,
when is good timing ?
	+1 version: includes replacement patch-set
	+2 version: includes remove      patch-set
or
	+1 version: includes both replacement/remove patch-set

Best regards

[PATCH 1/x][RFC] ASoC: remove rtd->platform checck

[Kuninori Morimoto]

Now, we are ready to replace rtd->platform to rtdcom list.
>From this patch, rtd->platform check is no longer needed.
It will be replaced into rtdcom.

[PATCH 7/x][RFC] ASoC: ac97: replace codec to component

[Kuninori Morimoto]

Now we can replace Codec to Component. Let's do it.

Note:
	xxx_codec_xxx()		->	xxx_component_xxx()

To keep compatibilty, this patch adds snd_soc_xxx_ac97_codec()
macro. These will be removed when all codec code was removed.

Applied "ASoC: sh: fsi: replace platform to component" to the asoc tree

[Mark Brown]

The patch

   ASoC: sh: fsi: replace platform to component

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git 

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

Applied "ASoC: intel: atom: replace platform to component" to the asoc tree

[Mark Brown]

The patch

   ASoC: intel: atom: replace platform to component

has been applied to the asoc tree at

   https://git.kernel.org/pub/scm/linux/kernel/git/broonie/sound.git

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
