[1/7] ASoC: dt-bindings: fsl_rpmsg: Add a property to assign the rpmsg channel commit: 3570e6873b1a506bca4b5788d71141944c55132c [2/7] ASoC: imx-audio-rpmsg: Create rpmsg channel for MICFIL commit: f04189e0b85f6bbd10679e71061bf6d1ced5c539 [3/7] ASoC: imx-pcm-rpmsg: Register different platform drivers commit: b2c2a947b3412f6edb9a86f5b12d6420958e67ba [4/7] ASoC: imx-pcm-rpmsg: Multi-channel support for sound card based on rpmsg commit: bdc0f6ca1c079ba790e0e227cff6164feae90460 [5/7] ASoC: fsl_rpmsg: Register different ASoC machine devices commit: 76a874caeab596972f529968aa0d19d4ba1d2197 [6/7] ASoC: fsl_rpmsg: Multi-channel support in CPU DAI driver commit: f26c1bb8a8ebe72748a3bb6f5d75079b642a33e8 [7/7] ASoC: imx-rpmsg: Assign platform driver used by machine driver to link with commit: 4b48440ea390bada41928920446928beb3652a76 All being well this means that it will be integrated into the linux-next tree (usually sometime in the next 24 hours) and sent to Linus during the next merge window (or sooner if it is a bug fix), however if problems are discovered then the patch may be dropped or reverted. You may get further e-mails resulting from automated or manual testing and review of the tree, please engage with people reporting problems and send followup patches addressing any issues that are reported if needed. If any updates are required or you are submitting further changes they should be sent as incremental updates against current git, existing patches will not be replaced. Please add any relevant lists and maintainers to the CCs when replying to this mail. Thanks, Mark
At a previous time, we have successfully created a virtual sound card based on rpmsg. The sound card works under this mechanism Cortex-A core tells the Cortex-M core the format, rate, channel, .etc configuration of the PCM parameters and Cortex-M controls real hardware devices such as SAI and DMA. From the view of Linux side, the sound card is bound to a rpmsg channel through which it can access SAI. Here these patches are introduced to create a new virtual sound card to access MICFIL based on a new created rpmsg channel. It's easy to create a new rpmsg channel for MICFIL through rpmsg name service announcment. Also the other ASoC components bound to this rpmsg MICFIL sound card will be registered with these patches. If other sound cards using different hardware devices needs to be created over rpmsg in the future, these patches can be referred. changes in v3 - Delete the statement referring to linux drivers in dts changes in v2: - Rename property in bindings file according to Krzysztof's comments - Update codes and comments according to Shengjiu's comments Chancel Liu (7): ASoC: dt-bindings: fsl_rpmsg: Add a property to assign the rpmsg channel ASoC: imx-audio-rpmsg: Create rpmsg channel for MICFIL ASoC: imx-pcm-rpmsg: Register different platform drivers ASoC: imx-pcm-rpmsg: Multi-channel support for sound card based on rpmsg ASoC: fsl_rpmsg: Register different ASoC machine devices ASoC: fsl_rpmsg: Multi-channel support in CPU DAI driver ASoC: imx-rpmsg: Assign platform driver used by machine driver to link with .../devicetree/bindings/sound/fsl,rpmsg.yaml | 36 +++++++++++++++++-- sound/soc/fsl/fsl_rpmsg.c | 6 ++-- sound/soc/fsl/imx-audio-rpmsg.c | 3 +- sound/soc/fsl/imx-pcm-rpmsg.c | 10 ++++-- sound/soc/fsl/imx-rpmsg.c | 6 +++- 5 files changed, 51 insertions(+), 10 deletions(-) -- 2.25.1
