[PATCH v3 00/42] ep93xx device tree conversion
by Nikita Shubin via B4 Relay 13 Nov '23

13 Nov '23

This series aims to convert ep93xx from platform to full device tree support. The main goal is to receive ACK's to take it via Arnd's arm-soc branch. I've moved to b4, tricking it to consider v0 as v1, so it consider's this version to be v3, this exactly the third version. Link to previous versions: https://lore.kernel.org/all/20230424123522.18302-1-nikita.shubin@maquefel.m… Major changes with clocks: - split all ep93xx clk into two groups: - those who are special to ep93xx (i.e. can't be implemented via standard clk's) and use special swlocked registers - those who can be implemented via devm_clk_hw_register_gate, etc... - moved all clk's that are not used via device tree to SoC driver - dropped init and globals - devm_* everywhere Other notable changes: - added a global spinlock for SoC driver to protect swlocked register's. - moved dts file into cirrus - dropped "dt-bindings: gpio: Add Cirrus EP93xx" as it was taken by Bartosz via gpio subsystem on master v6.5-rc2-89-g3acbd4602b05: make dtbs_check ``` make -j34 -C build-linux ARCH=arm CROSS_COMPILE=armv4t-softfloat-linux-gnueabi- dtbs_check -s arch/arm/boot/dts/cirrus/ep93xx-edb9302.dtb:0:0: /soc/spi@808a0000/codec@0: failed to match any schema with compatible: ['cirrus,cs4271'] /home/maquefel/workshop/ts7250-boot-build/build-linux/arch/arm/boot/dts/cirrus/ep93xx-edb9302.dtb: sound: 'simple-audio-card,convert-sample-format' does not match any of the regexes: '^simple-audio-card,codec(@[0-9a-f]+)?$', '^simple-audio-card,cpu(@[0-9a-f]+)?$', '^simple-audio-card,dai-link(@[0-9a-f]+)?$', '^simple-audio-card,plat(@[0-9a-f]+)?$', 'pinctrl-[0-9]+' From schema: /home/maquefel/workshop/ts7250-boot-build/linux/Documentation/devicetree/bindings/sound/simple-card.yaml ``` cirrus,cs4271 is defined in linux/Documentation/devicetree/bindings/sound/cs4271.txt `make dt_binding_check` shows no issues.

[RFC PATCH v8 00/13] Add audio support in v4l2 framework
by Shengjiu Wang 07 Nov '23

07 Nov '23

Audio signal processing also has the requirement for memory to memory similar as Video. This asrc memory to memory (memory ->asrc->memory) case is a non real time use case. User fills the input buffer to the asrc module, after conversion, then asrc sends back the output buffer to user. So it is not a traditional ALSA playback and capture case. It is a specific use case, there is no reference in current kernel. v4l2 memory to memory is the closed implementation, v4l2 current support video, image, radio, tuner, touch devices, so it is not complicated to add support for this specific audio case. Because we had implemented the "memory -> asrc ->i2s device-> codec" use case in ALSA. Now the "memory->asrc->memory" needs to reuse the code in asrc driver, so the first 3 patches is for refining the code to make it can be shared by the "memory->asrc->memory" driver. The main change is in the v4l2 side, A /dev/vl4-audioX will be created, user applications only use the ioctl of v4l2 framework. Other change is to add memory to memory support for two kinds of i.MX ASRC module. changes in v8: - refine V4L2_CAP_AUDIO_M2M to be 0x00000008 - update doc for FIXED_POINT - address comments for imx-asrc changes in v7: - add acked-by from Mark - separate commit for fixed point, m2m audio class, audio rate controls - use INTEGER_MENU for rate, FIXED_POINT for rate offset - remove used fmts - address other comments for Hans changes in v6: - use m2m_prepare/m2m_unprepare/m2m_start/m2m_stop to replace m2m_start_part_one/m2m_stop_part_one, m2m_start_part_two/m2m_stop_part_two. - change V4L2_CTRL_TYPE_ASRC_RATE to V4L2_CTRL_TYPE_FIXED_POINT - fix warning by kernel test rebot - remove some unused format V4L2_AUDIO_FMT_XX - Get SNDRV_PCM_FORMAT from V4L2_AUDIO_FMT in driver. - rename audm2m to viaudm2m. changes in v5: - remove V4L2_AUDIO_FMT_LPCM - define audio pixel format like V4L2_AUDIO_FMT_S8... - remove rate and format in struct v4l2_audio_format. - Add V4L2_CID_ASRC_SOURCE_RATE and V4L2_CID_ASRC_DEST_RATE controls - updata document accordingly. changes in v4: - update document style - separate V4L2_AUDIO_FMT_LPCM and V4L2_CAP_AUDIO_M2M in separate commit changes in v3: - Modify documents for adding audio m2m support - Add audio virtual m2m driver - Defined V4L2_AUDIO_FMT_LPCM format type for audio. - Defined V4L2_CAP_AUDIO_M2M capability type for audio m2m case. - with modification in v4l-utils, pass v4l2-compliance test. changes in v2: - decouple the implementation in v4l2 and ALSA - implement the memory to memory driver as a platfrom driver and move it to driver/media - move fsl_asrc_common.h to include/sound folder Shengjiu Wang (13): ASoC: fsl_asrc: define functions for memory to memory usage ASoC: fsl_easrc: define functions for memory to memory usage ASoC: fsl_asrc: move fsl_asrc_common.h to include/sound ASoC: fsl_asrc: register m2m platform device ASoC: fsl_easrc: register m2m platform device media: uapi: Add V4L2_CAP_AUDIO_M2M capability flag media: v4l2: Add audio capture and output support media: uapi: Define audio sample format fourcc type media: uapi: Add V4L2_CTRL_CLASS_M2M_AUDIO media: uapi: Add V4L2_CTRL_TYPE_FIXED_POINT media: uapi: Add audio rate controls support media: imx-asrc: Add memory to memory driver media: vim2m_audio: add virtual driver for audio memory to memory .../userspace-api/media/v4l/buffer.rst | 6 + .../userspace-api/media/v4l/common.rst | 1 + .../media/v4l/dev-audio-mem2mem.rst | 71 + .../userspace-api/media/v4l/devices.rst | 1 + .../media/v4l/ext-ctrls-audio-m2m.rst | 41 + .../userspace-api/media/v4l/pixfmt-audio.rst | 87 ++ .../userspace-api/media/v4l/pixfmt.rst | 1 + .../media/v4l/vidioc-enum-fmt.rst | 2 + .../media/v4l/vidioc-g-ext-ctrls.rst | 17 +- .../userspace-api/media/v4l/vidioc-g-fmt.rst | 4 + .../media/v4l/vidioc-querycap.rst | 3 + .../media/v4l/vidioc-queryctrl.rst | 9 +- .../media/videodev2.h.rst.exceptions | 4 + .../media/common/videobuf2/videobuf2-v4l2.c | 4 + drivers/media/platform/nxp/Kconfig | 12 + drivers/media/platform/nxp/Makefile | 1 + drivers/media/platform/nxp/imx-asrc.c | 1186 +++++++++++++++++ drivers/media/test-drivers/Kconfig | 9 + drivers/media/test-drivers/Makefile | 1 + drivers/media/test-drivers/vim2m_audio.c | 680 ++++++++++ drivers/media/v4l2-core/v4l2-ctrls-api.c | 5 +- drivers/media/v4l2-core/v4l2-ctrls-core.c | 2 + drivers/media/v4l2-core/v4l2-ctrls-defs.c | 16 + drivers/media/v4l2-core/v4l2-dev.c | 17 + drivers/media/v4l2-core/v4l2-ioctl.c | 66 + include/media/v4l2-dev.h | 2 + include/media/v4l2-ioctl.h | 34 + .../fsl => include/sound}/fsl_asrc_common.h | 60 + include/uapi/linux/v4l2-controls.h | 9 + include/uapi/linux/videodev2.h | 42 + sound/soc/fsl/fsl_asrc.c | 144 ++ sound/soc/fsl/fsl_asrc.h | 4 +- sound/soc/fsl/fsl_asrc_dma.c | 2 +- sound/soc/fsl/fsl_easrc.c | 233 ++++ sound/soc/fsl/fsl_easrc.h | 6 +- 35 files changed, 2771 insertions(+), 11 deletions(-) create mode 100644 Documentation/userspace-api/media/v4l/dev-audio-mem2mem.rst create mode 100644 Documentation/userspace-api/media/v4l/ext-ctrls-audio-m2m.rst create mode 100644 Documentation/userspace-api/media/v4l/pixfmt-audio.rst create mode 100644 drivers/media/platform/nxp/imx-asrc.c create mode 100644 drivers/media/test-drivers/vim2m_audio.c rename {sound/soc/fsl => include/sound}/fsl_asrc_common.h (60%) -- 2.34.1

[PATCH 1/3] soundwire: qcom: drop unneeded DAI .set_stream callback
by Krzysztof Kozlowski 06 Nov '23

Qualcomm Soundwire controller drivers do not support multi-link setups, so DAI .set_stream() callback will not be used. What's more, if called it will overwrite the sdw_stream_runtime runtime set in DAI .startup (qcom_swrm_startup()) causing issues (unsupported multi-link error) when two Soundwire controllers are passed as codec DAIs.

[PATCH AUTOSEL 5.15 13/28] ASoC: codecs: wsa-macro: handle component name prefix
by Sasha Levin 04 Nov '23

04 Nov '23

From: Krzysztof Kozlowski <krzysztof.kozlowski(a)linaro.org> [ Upstream commit c29e5263d32a6d0ec094d425ae7fef3fa8d4da1c ] When comparing widget names in wsa_macro_spk_boost_event(), consider also the component's name prefix. Otherwise the WSA codec won't have proper mixer setup resulting in no sound playback through speakers.
