[alsa-devel] [PATCH 0/7 v2] ASoC: merge audio-graph-scu into audio-graph - final step
Hi Mark, Tony
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 final step patches.
Tony, I think 1) and 3) patch will solve your issue. Can you please test these ?
Kuninori Morimoto (7): 1) ASoC: simple-card-utils: care endpoint reg for asoc_simple_card_get_dai_id() 2) ASoC: audio-graph-card: merge audio-graph-scu-card on Doc 3) ASoC: audio-graph-card: merge audio-graph-scu-card 4) ASoC: audio-graph-card: tidyup mclk-fs method 5) ASoC: audio-graph-card: tidyup convert_rate/channel method 6) ASoC: audio-graph-scu-card: remove audio-graph-scu-card on Doc 7) ASoC: audio-graph-scu-card: remove audio-graph-scu-card

commit b6f3fc005a2c8 ("ASoC: simple-card-utils: fixup asoc_simple_card_get_dai_id() counting") fixuped getting DAI ID method. But, we need to consider about endpoint case, too. This patch fixup it.
For example) MIXer case
DAI0 -+- CPU <--> Codec - DAI0 DAI1 /
/* CPU has 2 DAIs */ CPU { port { cpu-ep0: endpint@0 { reg = <0>; /* for DAI0 */ remote-endpoint = <codec-ep0>; }; cpu-ep1: endpint@1 { reg = <1>; /* for DAI1 */ remote-endpoint = <codec-ep1>; }; }; }
/* Codec has 1 DAI */ Codec { port { reg = <0>; /* both are for DAI0 */ codec-ep0: endpint@0 { remote-endpoint = <cpu-ep0>; }; codec-ep1: endpint@1 { remote-endpoint = <cpu-ep1>; }; }; }

audio-graph-card and audio-graph-scu-card are very similar driver, but the former is supporting normal sound card, the latter is supporting DPCM sound card.
We couldn't use normal sound and DPCM sound in same sound card by audio-graph-card. This patch merges both feature into it on Documentation. Now we can use both feature on same driver.

audio-graph-card and audio-graph-scu-card are very similar driver, but the former is supporting normal sound card, the latter is supporting DPCM sound card.
We couldn't use normal sound and DPCM sound in same sound card by audio-graph-card. This patch merges both sound card into it. Now we can use both feature on same driver.
Works for me:

Current audio-graph-card is handling "mclk-fs" by many way. But, it is not useful and readable. We want to do is that allow having mclk-fs everywere. This patch support it. It will be overwrote if lower node has it.
sound { mclk-fs = <xxx>; // initial };
codec { ports { mclk-fs = <xxx>; // overwrite port { mclk-fs = <xxx>; // overwrite endpoint { mclk-fs = <xxx>; // overwrite }; }; }; };

Hi Mark, Tony
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 final step patches.
Tony, I think 1) and 3) patch will solve your issue. Can you please test these ?
Getting closer.. The DAI instances get mapped the wrong way around for me:
soc-audio-graph-card soundcard: cpcap-hifi <-> 40124000.mcbsp mapping ok asoc-audio-graph-card soundcard: cpcap-hifi <-> 40126000.mcbsp-dai0 mapping ok asoc-audio-graph-card soundcard: mdm-call <-> 40126000.mcbsp-dai1 mapping ok
The second line above should not have cpcap-hifi PMIC codec instance but the cpcap-voice PMIC codec instance as below:
soc-audio-graph-card soundcard: cpcap-hifi <-> 40124000.mcbsp mapping ok asoc-audio-graph-card soundcard: cpcap-voice <-> 40126000.mcbsp-dai0 mapping ok asoc-audio-graph-card soundcard: mdm-call <-> 40126000.mcbsp-dai1 mapping ok
Any ideas why it thinks mcbsp2 has two DAIs instead of mcbsp3 having two DAIs?
The dts snippet I'm now using is below.

Tony

Sorry but I'm not good at your system. Can you show me the name-mapping ? which endpoint is for cpcap-hifi, cpcap-voice, mdm-call ?
and, DAI number mapping, too ? for example cpcap-hifi = DAI0 cpcap-voice = DAI1 etc, etc,...

Getting closer.. The DAI instances get mapped the wrong way around for me:
So I added reg properties to the cpcap codec end too and now I get the mapping set right:
asoc-audio-graph-card soundcard: cpcap-hifi <-> 40124000.mcbsp mapping ok asoc-audio-graph-card soundcard: cpcap-voice <-> 40126000.mcbsp-dai0 mapping ok asoc-audio-graph-card soundcard: mdm-call <-> 40126000.mcbsp-dai1 mapping ok
Hmm I wonder if this will now need all the dts files updated for codecs with multiple DAIs?
Also audio play does not work for me with these changes it seems.. My updated codec end snippet below.

OK, good to know.

It is OF graph maintainer's request.
But.. Hmm... to keep compatibility, use previous style, make sense ?
if (endpoint had reg) use it else if (port had reg) use it else use endpoint count
Also audio play does not work for me with these changes it seems.. My updated codec end snippet below.
Hmm...

I guess it that works and is easy to add :) Maybe warn about needing to add a reg property too?

No idea why audio no longer works.. It's like clocks suddenly don't work or as if something was still mapped to a wrong codec.

Yes, both of these seem like a good idea.

OK found out that loading my WIP codec driver related modules automatically on boot does not work. And loading the modules manually after boot works.. So it seems to be some -EPROBE_DEFER type issue somewhere unrelated to the graph changes and I was able to test this series.
Patches 1 & 3 work just great for me now, I'll reply separately with my acks for those two.
Thanks,
Tony
