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.

This is v2 of step3 patches.

I mentioned that step4 patch-set will be based on OF-graph posted patch, but, I could solve it without posted patch. There is no blocker anymore. Thus, I included blocked patch on step3.

Kuninori Morimoto (5): ASoC: simple-card-utils: fixup asoc_simple_card_get_dai_id() counting 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

New subject: [alsa-devel] [PATCH v2 1/5] ASoC: simple-card-utils: fixup asoc_simple_card_get_dai_id() counting

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

asoc_simple_card_get_dai_id() returns DAI ID, but it is based on DT node's "endpoint" position. Almost all cases 1 port has 1 endpoint, thus, it was no problem. But in reality, port : endpoint = 1 : N, thus, counting endpoint is BUG, it should based on "port" ID. This patch fixup it.

The patch

ASoC: simple-card-utils: fixup asoc_simple_card_get_dai_id() counting

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 send followup patches addressing any issues that are reported if needed.

If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced.

Please add any relevant lists and maintainers to the CCs when replying to this mail.

Thanks, Mark

New subject: [alsa-devel] [PATCH v2 2/5] ASoC: audio-graph-scu-card: care link / dai count

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

New subject: [alsa-devel] [PATCH v2 3/5] ASoC: audio-graph-scu-card: use cpu/codec pointer on graph_dai_props

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

New subject: [alsa-devel] [PATCH v2 5/5] ASoC: audio-graph-card: use cpu/codec pointer on graph_dai_props

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
