It proposes to use the "spdif_receiver" and "spdif_transmitter" drivers instead of the dummy codec. This is a first step in using the S/PDIF controller with the ASRC. The five first patches add compatibility with the pair of codecs "spdif_receiver" and "spdif_transmitter" with a new compatible, "fsl,imx-audio-generic". Codec parameters are set with default values. Consequently, the driver is modified to work with multi-codec use cases. It can get 2 codecs phandles from the device tree, and the "fsl_asoc_card_priv" struct now has 2 "codec_priv" to store properties of both codecs. It is fixed to 2 codecs as only "fsl,imx-audio-generic" uses multiple codecs at the moment. However, the driver now uses for_each_codecs macros when possible to ease future implementations of multi-codec configurations. The remaining patches add configuration options for the device tree. They configure the CPU DAI when using "fsl,imx-audio-generic". These options are usually hard-coded in "fsl-asoc-card.c" for each audio codec. Because the generic codec could be used with other CPU DAIs than the S/PDIF controller, setting these parameters could be required. This series of patch was successfully built for arm64 and x86 on top of the latest for-next branch of the ASoC git tree on the 14th of December. These modifications have also been tested on an i.MX8MN evaluation board, with a linux kernel RT v6.1.26-rt8. Best regards, Elinor Montmasson Changelog: v2 -> v3: * when the bitmaster or framemaster are retrieved from the device tree, the driver will now compare them with the two codecs possibly given in the device tree, and not just the first codec. * improve driver modifications to use multiple codecs for better integration of future multi-codec use cases: * use for_each_codec macros when possible. * "fsl_asoc_card_priv" struct now has 2 "codec_priv" as the driver can currently retrieve 2 codec phandles from the device tree. * fix subject of patch 10/10 to follow the style of the subsystem and previous commits of the file. * v2 patch series at: https://lore.kernel.org/alsa-devel/20231027144734.3654829-1-elinor.montmasson@savoirfairelinux.com/ v1 -> v2: * replace use of the dummy codec by the pair of codecs "spdif_receiver" / " spdif_transmitter". * adapt how dai links codecs are used to take into account the possibility for multiple codecs per link. * change compatible name. * adapt driver to be able to register two codecs given in the device tree. * v1 patch series at: https://lore.kernel.org/alsa-devel/20230901144550.520072-1-elinor.montmasson@savoirfairelinux.com/ Elinor Montmasson (10): ASoC: fsl-asoc-card: add support for dai links with multiple codecs ASoC: fsl-asoc-card: add second dai link component for codecs ASoC: fsl-asoc-card: add compatibility to use 2 codecs in dai-links ASoC: fsl-asoc-card: add new compatible for a generic codec use case ASoC: fsl-asoc-card: set generic codec as clock provider ASoC: fsl-asoc-card: add dts property "cpu-slot-width" ASoC: fsl-asoc-card: add dts property "cpu-slot-num" ASoC: fsl-asoc-card: add dts properties "cpu-sysclk-freq" ASoC: fsl-asoc-card: add dts properties "cpu-sysclk-dir-out" ASoC: bindings: fsl-asoc-card: add compatible for generic codec .../bindings/sound/fsl-asoc-card.txt | 28 +- sound/soc/fsl/fsl-asoc-card.c | 299 +++++++++++------- 2 files changed, 218 insertions(+), 109 deletions(-)
