[PATCH v2 00/16] ASoC: Replace dpcm_playback/capture to playback/capture_only
by Kuninori Morimoto 09 Apr '24

09 Apr '24

Hi Mark This is v2 patch-set When we use DPCM, we need to set dpcm_playback/capture flag. If these flag are set, soc_get_playback_capture() will check its availability, but non DPCM doesn't need such special flags. OTOH, it cares playback/capture_only flag. It is needed. This patch remove DPCM special flag, and replace it playback/capture_only flag if needed. v1 -> v2 - based on latest ASoC branch - keep comment on Intel - tidyup patch title - tidyup DPCM BE warning output condition -

[PATCH v1 0/2] ASoC: meson: implement link-name optional property in meson audio card
by Dmitry Rokosov 08 Apr '24

08 Apr '24

The 'link-name' is optional feature in the Device Tree that allows users to customize the name associated with the DAI link and PCM stream. This feature provides enhanced flexibility in DAI naming conventions, leading to improved system integration and a better user experience.

[GIT PULL FOR v6.10] Add imx-asrc m2m audio rate control driver
by Hans Verkuil 08 Apr '24

08 Apr '24

Hi Mauro, This adds support for the imx-asrc m2m audio rate control driver. Most of these patches add support for the new v4l-audioX device nodes and related types, and adding support for fixed point control types. The ASoC patches have been acked by Mark Brown. It also adds a vim2m-audio test driver so we can test the v4l-audio infrastructure. Since V4L2 is fourcc-based all the way, directly using snd_pcm_format_t values is not an option: fourcc's are expected to be printable characters, and it is pretty much certain that there are applications that show it like that to the end-user. The utilities in v4l-utils certainly do, and it is in fact a perfectly reasonable thing to do. So instead we map the snd_pcm_format_t value to a fourcc with v4l2_audfmt_to_fourcc and map it back with v4l2_fourcc_to_audfmt. This PR is using v15 of the patch series: https://patchwork.linuxtv.org/project/linux-media/list/?series=12460 And the corresponding v4l-utils patch series is here: https://patchwork.linuxtv.org/user/todo/linux-media/?series=12074 Regards, Hans The following changes since commit b14257abe7057def6127f6fb2f14f9adc8acabdb: media: rcar-isp: Disallow unbind of devices (2024-03-07 16:35:13 +0100) are available in the Git repository at: git://linuxtv.org/hverkuil/media_tree.git tags/br-audio for you to fetch changes up to af06c8792653c42d1f126505ec9180255091d94e: media: vim2m-audio: add virtual driver for audio memory to memory (2024-03-19 15:55:38 +0100) ---------------------------------------------------------------- Tag branch ---------------------------------------------------------------- Hans Verkuil (1): media: v4l2-ctrls: add support for fraction_bits Shengjiu Wang (15): 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 audio rate controls support media: uapi: Declare interface types for Audio media: uapi: Add an entity type for audio resampler media: vivid: add fixed point test controls media: imx-asrc: Add memory to memory driver media: vim2m-audio: add virtual driver for audio memory to memory Documentation/userspace-api/media/mediactl/media-types.rst | 11 + Documentation/userspace-api/media/v4l/buffer.rst | 6 + Documentation/userspace-api/media/v4l/common.rst | 1 + Documentation/userspace-api/media/v4l/dev-audio-mem2mem.rst | 71 +++ Documentation/userspace-api/media/v4l/devices.rst | 1 + Documentation/userspace-api/media/v4l/ext-ctrls-audio-m2m.rst | 59 +++ Documentation/userspace-api/media/v4l/pixfmt-audio.rst | 100 ++++ Documentation/userspace-api/media/v4l/pixfmt.rst | 1 + Documentation/userspace-api/media/v4l/vidioc-enum-fmt.rst | 2 + Documentation/userspace-api/media/v4l/vidioc-g-ext-ctrls.rst | 4 + Documentation/userspace-api/media/v4l/vidioc-g-fmt.rst | 4 + Documentation/userspace-api/media/v4l/vidioc-querycap.rst | 3 + Documentation/userspace-api/media/v4l/vidioc-queryctrl.rst | 11 +- Documentation/userspace-api/media/videodev2.h.rst.exceptions | 3 + MAINTAINERS | 17 + drivers/media/common/videobuf2/videobuf2-v4l2.c | 4 + drivers/media/platform/nxp/Kconfig | 13 + drivers/media/platform/nxp/Makefile | 1 + drivers/media/platform/nxp/imx-asrc.c | 1256 +++++++++++++++++++++++++++++++++++++++++++++++++++ drivers/media/test-drivers/Kconfig | 10 + drivers/media/test-drivers/Makefile | 1 + drivers/media/test-drivers/vim2m-audio.c | 793 ++++++++++++++++++++++++++++++++ drivers/media/test-drivers/vivid/vivid-core.h | 2 + drivers/media/test-drivers/vivid/vivid-ctrls.c | 26 ++ drivers/media/v4l2-core/v4l2-compat-ioctl32.c | 9 + drivers/media/v4l2-core/v4l2-ctrls-api.c | 1 + drivers/media/v4l2-core/v4l2-ctrls-core.c | 93 +++- drivers/media/v4l2-core/v4l2-ctrls-defs.c | 10 + drivers/media/v4l2-core/v4l2-dev.c | 21 + drivers/media/v4l2-core/v4l2-ioctl.c | 66 +++ drivers/media/v4l2-core/v4l2-mem2mem.c | 13 +- include/media/v4l2-ctrls.h | 13 +- include/media/v4l2-dev.h | 2 + include/media/v4l2-ioctl.h | 34 ++ {sound/soc/fsl => include/sound}/fsl_asrc_common.h | 60 +++ include/uapi/linux/media.h | 2 + include/uapi/linux/v4l2-controls.h | 9 + include/uapi/linux/videodev2.h | 50 +- 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 +- 43 files changed, 3145 insertions(+), 27 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%)
