I already saw this.
You said "all current mainline drivers using the library use cyclic DMA."
Does this mean the following drivers use "snd_dmaengine_pcm_open" ?
However, the following drivers don't use any ASoC DMA framework, right ?.
E.g. these drivers call dma_request_channel directly.
That is to say, some drivers ASoC DMA framework. However some drivers
don't use any ASoC DMA framework.
Why didn't you do porting to your saying "ASoC DMA framework"?
