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

[Kuninori Morimoto]

Hi Mark

I noticed that there are 1 small bug.
It is not a big deal, but I want to fixup.
Please let me know if v1 looks OK,
then, I will post v2 patch.
If v1 is not OK, then, I don't post v2.

> 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.

> I think. [09/15] patch add it on soc-core.

> 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
