The current DT bindings assume that the DMA will be performed by the devices through their parent DT node, and rely on that assumption for the address translation using dma-ranges. However, some SoCs have devices that will perform DMA through another bus, with separate address translation rules. We therefore need to express that relationship, through the special interconnect name "dma".
