Basically it supports basic CPU-Codec connection, and is also supporting DPCM connection. Because it was forcibly expanded to DPCM, DT parsing is very limited and very difficult to add new features on it, for example Multi CPU/Codec support, Codec2Codec support, etc. And some users want to use Audio-Graph-Card as basic connection and expand/customize its own settings on it. This patch adds more flexible new Audio-Graph-Card2 driver for it. Audio-Graph-Card and Audio-Graph-Card2 are similar, but don't have full compatibility. The reason why I need Audio-Graph-Card2 instead of update Audio-Graph-Card is that it is very difficult to keep compatibilty. Audio-Graph-Card2 supports Normal Connection, DPCM Connection, Multi CPU/Codec Connection, Codec2Codec Connection, and possible to Customizing. This patch-set adds Audio-Graph-Card2 driver and customized driver sample, and DT settings sample which can be used for testing. To enable testing/debuging, this patch-set also adds Test-Component driver. We already have Dummy Component and/or Dummy DAI on soc-utils, but 1) we can't use it from DT, 2) it do nothing. Added new Test-Component can be used from DT, and it can indicate called function name. We can use it to trace callback order / understanding ALSA SoC behavior, etc. Sample DT settings which can be used for testing is using Test-Component. This patch set includes sample DT for custome driver and/or audio-graph-card2. You can easily try to use/test it if you added below line to your DT file. It needs below CONFIGs. It will probe sample Sound Card which has Normal/DPCM/Multi/Codec2Codec connections. #include "../../../../../sound/soc/generic/audio-graph-card2-sample.dtsi" CONFIG_SND_AUDIO_GRAPH_CARD2 CONFIG_SND_SAMPLE_CUSTOM_CARD CONFIG_SND_TEST_COMPONENT There are some notes. Because Audio Graph Card2 is still under experimental stage, it will indicate such warning when probing, and the DT might be updated/exchanged. It can use Codec2Codec, but it will start automatically when probed, and can't stop it so far. It should be updated. 1 - 2 : add Test-Component driver 3 - 9 : add Audio-Graph-Card2 driver 10 : add Audio-Graph-Card2 base custome driver sample 11 - 14 : Audio-Graph-Card2 driver / custome driver DT sample Link: https://lore.kernel.org/r/87k0xszlep.wl-kuninori.morimoto.gx@renesas.com Link: https://lore.kernel.org/r/871r8u4s6q.wl-kuninori.morimoto.gx@renesas.com v1 -> v2 - don't use "port" base for_each loop Kuninori Morimoto (14): 1 ASoC: test-component: add Test Component YAML bindings 2 ASoC: test-component: add Test Component for Sound debug/test 3 ASoC: simple-card-utils: add asoc_graph_is_ports0() 4 ASoC: simple-card-utils: add codec2codec support 5 ASoC: audio-graph-card2: add Audio Graph Card2 driver 6 ASoC: audio-graph-card2: add DPCM support 7 ASoC: audio-graph-card2: add Multi CPU/Codec support 8 ASoC: audio-graph-card2: add Codec2Codec support 9 ASoC: audio-graph-card2: add Yaml Document 10 ASoC: sample-custom-card: add Audio Graph Card2 custome sample 11 ASoC: audio-graph-card2-sample.dtsi: add Sample DT for Audio Graph Card2 12 ASoC: audio-graph-card2-sample.dtsi: add DPCM sample 13 ASoC: audio-graph-card2-sample.dtsi: add Multi CPU/Codec sample 14 ASoC: audio-graph-card2-sample.dtsi: add Codec2Codec sample. .../sound/audio-graph-card2-items.yaml | 80 ++ .../bindings/sound/audio-graph-card2.yaml | 51 + .../bindings/sound/test-component.yaml | 33 + include/sound/graph_card.h | 24 + include/sound/simple_card_utils.h | 4 + sound/soc/generic/Kconfig | 20 + sound/soc/generic/Makefile | 6 + .../soc/generic/audio-graph-card2-sample.dtsi | 140 ++ sound/soc/generic/audio-graph-card2.c | 1252 +++++++++++++++++ sound/soc/generic/sample-custom-card.c | 160 +++ sound/soc/generic/simple-card-utils.c | 46 +- sound/soc/generic/test-component.c | 659 +++++++++ 12 files changed, 2474 insertions(+), 1 deletion(-) create mode 100644 Documentation/devicetree/bindings/sound/audio-graph-card2-items.yaml create mode 100644 Documentation/devicetree/bindings/sound/audio-graph-card2.yaml create mode 100644 Documentation/devicetree/bindings/sound/test-component.yaml create mode 100644 sound/soc/generic/audio-graph-card2-sample.dtsi create mode 100644 sound/soc/generic/audio-graph-card2.c create mode 100644 sound/soc/generic/sample-custom-card.c create mode 100644 sound/soc/generic/test-component.c
