[1/4] ASoC: dmaengine_pcm: Allow passing component name via config commit: cee28113db17f0de58df0eaea4e2756c404ee01f 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
Add DisplayPort audio support for Xilinx ZynqMP platforms. This depends on patch adding cyclic DMA mode for DPDMA driver: https://lore.kernel.org/all/20240228042124.3074044-3-vishal.sagar@amd.com/ If that patch is missing, starting an audio playback will fail with an ASoC error. The current DT is, for some reason, missing the DMA channels for the audio. This series adds that to the bindings and the dts file, but to support older dtb files without the audio DMA, the driver will not fail if the audio DMA is missing, but will just mark the audio support as disabled. The series also includes an improvement to the soc-generic-dmaengine-pcm.c, required to support two dmaengine_pcms.
