Hello, This is the v7 of the series of patches aiming to make the machine driver 'fsl-asoc-card' compatible with S/PDIF controllers on imx boards. The core of the contribution was merged with v6 of the series. v7 fixes the order of properties for new nodes in device-trees so that `compatible` is first in the list as recommended. These two patches update all in-tree device-trees to use the new 'fsl-asoc-card' properties. Note that as the old properties are still supported by `fsl-asoc-card`: - previous versions of in-tree device-trees are still supported. - out-of-tree device-trees are still supported. This series of patches was successfully built for arm64 and x86 on top of the latest "for-next" branch of the ASoC git tree on the 19th of August 2024. 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: v6 -> v7: - Changed the order of properties in new device-tree spdif-in/out nodes, so that `compatible` is first. - v6 patch series at: https://lore.kernel.org/all/20240627083104.123357-1-elinor.montmasson@xxxxxxxxxxxxxxxxxxxx/ v5 -> v6: - Remove applied patch "ASoC: fsl-asoc-card: set priv->pdev before using it". - Add backward compatibility with `imx-spdif` DT properties. - Squash removal of `imx-spdif.yaml` into patch updating `fsl-asoc-card.yaml`. - `fsl-asoc-card.yaml`: fix indentation, document use of compatible "fsl,imx-audio-spdif" only with "fsl,imx-sabreauto-spdif" or "fsl,imx6sx-sdb-spdif". - Explain better in commit messages why there are new DT properties that can be used with "fsl,imx-audio-spdif" and what are the benefits to use them. - v5 patch series at: https://lore.kernel.org/all/20240620132511.4291-1-elinor.montmasson@xxxxxxxxxxxxxxxxxxxx/ v4 -> v5: - Focus the contribution to bringing S/PDIF / ASRC support. - Instead of creating a new compatible for the S/PDIF `fsl-asoc-card` support, merge the driver `imx-spdif` into `fsl-asoc-card`, and keep the compatible. It preserves the base S/PDIF audio card support but also extends it with the possibility to use an ASRC. It also reduces code and driver duplication. - Following driver merge, adapt device trees using "fsl,imx-audio-spdif" compatible. - Use more `for_each_codecs` macros in `fsl-asoc-card` when adding multi-codec support. - Remove patches about new device-tree bindings that were not relevant for an S/PDIF specific support. - Improve DT schema changes. - Move `priv->pdev` assignment earlier in "fsl_asoc_card_probe()" to fix a NULL pointer dereference in "fsl_asoc_card_audmux_init()". - v4 patch series at: https://lore.kernel.org/all/20240515135411.343333-1-elinor.montmasson@xxxxxxxxxxxxxxxxxxxx/ v3 -> v4: - Use the standard TDM bidings, as defined in "tdm-slot.txt", for the new optional DT bindings setting the TDM slots number and width. - Use the clock DT bindings to optionally specify the CPU DAI system clock frequency, instead of a dedicated new binding. - Rename the new DT binding "cpu-sysclk-dir-out" to "cpu-system-clock-direction-out" to better follow the style of the simple-card driver. - Merge TX an RX bindings for CPU DAI system-clock, to better follow the style of the simple-card driver, and also as there was no use case in fsl-asoc-card where TX and RX settings had to be different. - Add the documentation for the new bindings in the new DT schema bindings documentation. Also add an example with the generic codec. - v3 patch series at: https://lore.kernel.org/alsa-devel/20231218124058.2047167-1-elinor.montmasson@xxxxxxxxxxxxxxxxxxxx/ 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 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 - v2 patch series at: https://lore.kernel.org/alsa-devel/20231027144734.3654829-1-elinor.montmasson@xxxxxxxxxxxxxxxxxxxx/ 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@xxxxxxxxxxxxxxxxxxxx/ Elinor Montmasson (2): arm64: dts: imx8m: update spdif sound card node properties ARM: dts: imx6: update spdif sound card node properties arch/arm/boot/dts/nxp/imx/imx6q-cm-fx6.dts | 15 +++++++++--- arch/arm/boot/dts/nxp/imx/imx6q-prti6q.dts | 15 +++++++++--- arch/arm/boot/dts/nxp/imx/imx6q-tbs2910.dts | 9 +++++-- arch/arm/boot/dts/nxp/imx/imx6qdl-apalis.dtsi | 15 +++++++++--- .../arm/boot/dts/nxp/imx/imx6qdl-apf6dev.dtsi | 9 +++++-- .../arm/boot/dts/nxp/imx/imx6qdl-colibri.dtsi | 15 +++++++++--- .../arm/boot/dts/nxp/imx/imx6qdl-cubox-i.dtsi | 9 +++++-- .../dts/nxp/imx/imx6qdl-hummingboard.dtsi | 9 +++++-- .../boot/dts/nxp/imx/imx6qdl-sabreauto.dtsi | 9 +++++-- .../boot/dts/nxp/imx/imx6qdl-wandboard.dtsi | 9 +++++-- .../arm/boot/dts/nxp/imx/imx6sx-sabreauto.dts | 9 +++++-- arch/arm/boot/dts/nxp/imx/imx6sx-sdb.dtsi | 9 +++++-- arch/arm64/boot/dts/freescale/imx8mm-evk.dtsi | 15 +++++++++--- arch/arm64/boot/dts/freescale/imx8mn-evk.dtsi | 15 +++++++++--- arch/arm64/boot/dts/freescale/imx8mq-evk.dts | 24 +++++++++++++++---- 15 files changed, 147 insertions(+), 39 deletions(-) -- 2.34.1
