Hi Mark Cc Bard, Pierre-Louis, Jerome, DT-ML This is v5 patch-set. Current ASoC is supporting CPU/Codec = N:M (N < M) connection by using ch_map idea. This patch-set expands it that all connection uses this idea, and no longer N < M limit [1][2]. Link: https://lore.kernel.org/r/87fs6wuszr.wl-kuninori.morimoto.gx@xxxxxxxxxxx [1] Link: https://lore.kernel.org/r/878r7yqeo4.wl-kuninori.morimoto.gx@xxxxxxxxxxx [2] This patch is tested on Audio-Graph-Card2 with sample dtsi, but needs Tested-by, at least from Intel. [PATCH 1/5] patch got Tested-by from Pierre-Louis / Jerome before, but v5 is using different idea from v4. Thus I didn't add below tag. Tested-by: Pierre-Louis Bossart <pierre-louis.bossart@xxxxxxxxxxxxxxx> Tested-by: Jerome Brunet <jbrunet@xxxxxxxxxxxx> v4 -> v5 - use cpu/codec index on ch_maps - separate card2 sample DT patch into prepare and new feature - ch-maps -> ch-map-idx on DT v3 -> v4 - add Jerome on To - add "description" on "ch-maps" v2 -> v3 - tidyup comment - use more clear connection image on DT - "ch_maps" -> "ch-maps" on DT - Add DT maintainer on "To:" for all patches v1 -> v2 - makes CPU/Codec connection relation clear on comment/sample - fixup type "connction" -> "connection" - makes error message clear Kuninori Morimoto (4): ASoC: makes CPU/Codec channel connection map more generic ASoC: audio-graph-card2: add CPU:Codec = N:M support ASoC: audio-graph-card2-custom-sample: add CPU/Codec = N:M sample dt-bindings: audio-graph-port: add ch-maps property Kuninori Morimoto (5): ASoC: makes CPU/Codec channel connection map more generic ASoC: audio-graph-card2: add CPU:Codec = N:M support ASoC: audio-graph-card2-custom-sample: tidyup comment / numbering ASoC: audio-graph-card2-custom-sample: add CPU/Codec = N:M sample dt-bindings: audio-graph-port: add ch-map-idx property .../bindings/sound/audio-graph-port.yaml | 7 +- include/sound/soc.h | 55 ++++++- .../audio-graph-card2-custom-sample.dtsi | 136 +++++++++++++++--- sound/soc/generic/audio-graph-card2.c | 49 +++++++ sound/soc/intel/boards/sof_sdw.c | 28 ++-- sound/soc/soc-core.c | 97 ++++++++++++- sound/soc/soc-dapm.c | 45 ++---- sound/soc/soc-pcm.c | 44 ++---- 8 files changed, 360 insertions(+), 101 deletions(-) -- 2.25.1
