[alsa-devel] [PATCH 00/15][RFC] ASoC: use snd_soc_dai_link_component style for simple card

[Kuninori Morimoto]

Hi Mark

I think ALSA SoC framework needs more update for modern style
As 1st step, codec/plaform are updated/converted to component style.
I think 2nd step is DAI/dai_link matching.
We want to use snd_soc_dai_link_component style instead of
legacy style for dai_link matching for CPU/Codec/Platform.
like this.

	[current]
	struct snd_soc_dai_link {
		...
		*cpu_name;
		*cpu_of_node;
		*cpu_dai_name;

		*codec_name;
		*codec_of_node;
		*codec_dai_name;
		*codecs;
		num_codecs;

		*platform_name;
		*platform_of_node;
		...
	}

	[we want]
	struct snd_soc_dai_link {
		...
		*cpus
		num_cpus;

		*codecs;
		num_codecs;

		*platform;
		...
	}

Above sample is still using CPU/Codec/Platform.
We can merge it into same snd_soc_dai_link_component list
if someone wants it. But anyway, CPU/Codec/Platform style
is not so bad, so far.

It will be more useful/simple code if we can use
snd_soc_dai_link_component for DAI instead of
xxx_name / xxx_of_node / xxx_dai_name.

Currently, only Codec is supporting/using snd_soc_dai_link_component
style. But we want to use it for CPU/Platform, too.
I know Shreyas is posting multi CPU style, then, it can support
snd_soc_dai_link_component style.

Using snd_soc_dai_link_component style for Platform is not difficult
I think. [09/15] patch add it on soc-core.
But, I can't test for all boards/platforms, thus,
I added [RFC] for these patches.

Now, we are still missing CPU part, but can use it for Codec/Platform.
These patches use it on simple/audio cards for Codec/Platform.
If these are OK, and if we could have CPU support in the future,
we can convert current legacy style to snd_soc_dai_link_component style
for all sound cards.

 1) -  8) use snd_soc_dai_link_component for Codec    on simple/audio card
 9) - 15) use snd_soc_dai_link_component for Platform on simple/audio card
