But our iommu/dma-ranges is 16GB, we still expect separate the 16GB dma-range like: a) display is in 0 - 4GB; b) vcodec is in 4GB - 8GB; c) camera is in 8GB - 12GB. We can not expect all the masters add a parent node for them, especial for the existed drivers/nodes. Thus, we add whole the 16GB dma-ranges in the parent "soc" node.
