For v2 my preference is to keep the wrapper, since it leaves the generic arm-dma350 driver and its binding untouched. Does that work for you, or would you rather see the dma-350 node itself carry a device-specific compatible, with the clocks, resets and memory-region described on it? I'd also like Robin's take on the arm-dma350 side before restructuring that far. Best regards, Jelly
