From 88c531b42a986c02a2630b84521d3dfe19b01686 Mon Sep 17 00:00:00 2001 From: Yong Wu Date: Tue, 11 Apr 2023 17:31:43 +0800 Subject: arm64: dts: mt8195: Add dma-ranges for the parent "soc" node After commit f1ad5338a4d5 ("of: Fix "dma-ranges" handling for bus controllers"), the dma-ranges property is not allowed for the leaf node. 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.
