From: Laurentiu Mihalcea <laurentiu.mihalcea@xxxxxxx> Add sof support on imx95. This series also includes some changes to the audio-graph-card2 binding required for the support. --- Changes in v3: - Ordered DT nodes alphabetically - Removed 'cpu' and 'cpu_ep' labels from binding example - Some small changes to the binding commit messages/titles. - Link to v2: https://lore.kernel.org/lkml/20241113195240.3699-1-laurentiumihalcea111@xxxxxxxxx/ Changes in v2: - Added new binding for 95's CM7 core with SOF. fsl,dsp.yaml is no longer used. - "hp-det-gpios" and "widgets" properties now reference the definitions from audio-graph.yaml - Removed extra empty spaces from DTS as suggested by Frank - Ordered 'edma2', 'sai3', 'wm8962' DT nodes alphabetically. The order of the nodes placed inside / is kept the same for readability - Ordered driver header files includes alphabetically as suggested by Frank - Removed "reg-names" and changed the maximum size of the "reg" property to 1 to align with the other NXP CPUs sharing the same programming model (i.e: audio processing with SOF). The region described in the DTS is the SRAM and the mailbox region is now hardcoded in the driver as an offset to the start of the SRAM region. - Added new binding with properties required by all NXP CPUs sharing the same programming model (i.e: audio processing with SOF). - Various driver adjustments made to accomodate the DT changes + some bug fixing related to the mboxes not being requested/free'd on resume/suspend. - Fixed value passed to "dma-channel-mask". A set bit means the channel is masked, not the other way around. - Link to v1: https://lore.kernel.org/lkml/20241023162114.3354-1-laurentiumihalcea111@xxxxxxxxx/ --- Laurentiu Mihalcea (5): ASoC: dt-bindings: add common binding for NXP audio processors ASoC: dt-bindings: support imx95's CM7 core ASoC: dt-bindings: audio-graph-card2: add widgets and hp-det-gpios support ASoC: SOF: imx: add driver for imx95 arm64: dts: imx: add imx95 dts for sof .../bindings/sound/audio-graph-card2.yaml | 4 + .../bindings/sound/fsl,imx95-cm7-sof.yaml | 44 ++ .../bindings/sound/fsl,sof-cpu.yaml | 35 ++ arch/arm64/boot/dts/freescale/Makefile | 1 + .../dts/freescale/imx95-19x19-evk-sof.dts | 75 ++++ sound/soc/sof/imx/Kconfig | 8 + sound/soc/sof/imx/Makefile | 2 + sound/soc/sof/imx/imx95.c | 401 ++++++++++++++++++ 8 files changed, 570 insertions(+) create mode 100644 Documentation/devicetree/bindings/sound/fsl,imx95-cm7-sof.yaml create mode 100644 Documentation/devicetree/bindings/sound/fsl,sof-cpu.yaml create mode 100644 arch/arm64/boot/dts/freescale/imx95-19x19-evk-sof.dts create mode 100644 sound/soc/sof/imx/imx95.c -- 2.34.1
