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 cyclic DMA patch has recently been accepted to the DMA tree. 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.
