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

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

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
