Something like "fsl-pcm-audio", but different from "fsl-pcm-audio" will be instantiated as a hardware block by device tree, "imx-pcm-audio" is pretty much like a ASoC wrapper for calling dmaengine driver. So there is no hardware block presenting this "device" in device tree, and we need to instantiate it from cpu DAI driver as Mark suggested.
Wait, is this the DMA controller? Because on PowerPC, we have device tree nodes for the DMA controller. Why don't you have one on i.MX?
