True, but as you said, the goal is to remove machine code. So instead
of having just a 'dma-coherent' property, shouldn't we have a
dma-method property, which could be dma-method = "coherent" or
dma-method = "marvell,io-coherent" and therefore allow the DT binding
to cover more use cases than just the default non-coherent and coherent
DMA operations?

Best regards,
