I'm not sure I agree. It seems that specifying nodes for each DMA channel (virtual or physical) is meaningless because the only property in the node is the "reg", which is really just a cell-index in disguise. My vote is to have a node only for the DMA engine, and let the DMA handle the virtual and physical channels internally. -- Timur Tabi Linux kernel developer at Freescale _______________________________________________ devicetree-discuss mailing list [email protected] https://lists.ozlabs.org/listinfo/devicetree-discuss
