Remove it for vcodec here. 1) For mediatek,vcodec-decoder.yaml and mediatek,vcodec-encoder.yaml, this property is in the leaf node, it is invalid as the above comment. Currently there is only mt8195 VENC node has this property in upstream. Indeed, VENC is affected, but it is not a fatal issue. Originally it expects its iova range locate at 4GB-8GB. However after that commit, its expectation doesn't come true, it will fall back to 0-4GB iova and also could work well. 2) For mediatek,vcodec-subdev-decoder.yaml, It already uses parent-child node, this property works. Instead, MediaTek iommu will control the masters' iova ranges by the master's larb/port id internally, then the dma-ranges property is unnecessary for the master's node.
