[PATCH 0/4] ASoC: merge audio-graph-scu into audio-graph - step3

[PATCH 0/4] ASoC: merge audio-graph-scu into audio-graph - step3

[Kuninori Morimoto]

Hi Mark

audio-graph     card can handle normal sound card, and
audio-graph-scu card can handle DPCM   sound card.
But, we can't use these feature in same time now.

So, this is the time to merge audio-graph and audio-graph-scu.
The patch-set are a little bit huge (and few patches are depend
on posted OF patch. I'm now waiting...),
thus, I separated these into few steps.

This is step3 patches.

After step3, the remaining patch is "merge audio-graph and audio-graph-scu"
and "remove audio-graph-scu" patches,
and, +1 more patch which is based on OF graph patches.
I'm posting it to OF ML, but no response so far.
Thus, step4 patch will be *after* OF graph patch.

Kuninori Morimoto (4):
  ASoC: audio-graph-scu-card: care link / dai count
  ASoC: audio-graph-scu-card: use cpu/codec pointer on graph_dai_props
  ASoC: audio-graph-scu-card: care multi DPCM codec_conf
  ASoC: audio-graph-card: use cpu/codec pointer on graph_dai_props

[PATCH 1/4] ASoC: audio-graph-scu-card: care link / dai count

[Kuninori Morimoto]

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

In DPCM case, it uses CPU-dummy / dummy-Codec dai links.
If sound card is caring only DPCM, link count = dai count,
but, if non DPCM case, link count != dai count.
Now, we want to merge audio-graph-card and audio-graph-scu-card,
then, we need to care both link / dai count more carefly
This patch cares it, and prepare for merging audio card

[PATCH 2/4] ASoC: audio-graph-scu-card: use cpu/codec pointer on graph_dai_props

[Kuninori Morimoto]

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

In  DPCM case, it uses CPU-dummy / dummy-Codec dai links, and
non DPCM case, it uses CPU-Codec dai links.

Now, we want to merge audio-graph-card and audio-graph-scu-card.

These sound cards are using silimar but not same logic on each functions.
Then, of course we want to share same logic.
To compromise, this patch uses cpu/codec pointer on audio-graph-scu-card.
It is same logic with audio-graph-card, thus easy merging.
This is prepare for merging audio card

Current audio-graph-scu-card didn't care about codec_conf
for multi DPCM case. This patch cares it.

[PATCH 4/4] ASoC: audio-graph-card: use cpu/codec pointer on graph_dai_props

[Kuninori Morimoto]

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

In  DPCM case, it uses CPU-dummy / dummy-Codec dai links, and
non DPCM case, it uses CPU-Codec dai links.

Now, we want to merge audio-graph-card and audio-graph-scu-card.

These sound cards are using silimar but not same logic on each functions.
Then, of course we want to share same logic.
To compromise, this patch uses cpu/codec pointer on audio-graph-card.
It is same logic with audio-graph-scu-card, thus easy merging.
This is prepare for merging audio card

I can't tell what a "ccnf" is reading this and there's no documentation :(

It means "snd_soc_codec_conf number" -> "codec_conf number" -> "ccnf_num".
I aligned it. I can update if it is better
