Thus we adjust the internal flow, separate the 16GB iova range by the master HW larbid/portid and add the dma-ranges property in the parent "soc" node. This also could avoid the users forget/abuse the iova regions. The commit f1ad5338a4d5 did affect the mt8195 venc, But it is not a fatal issue, it could also work well at 0-4GB iova. thus I don't add "Fixes:" tag. In this series, I add functions for mt8192/mt8195/mt8186, mt8188 will be in its special patchset. and the previous mt8173/mt8183...support 0-4GB only, no need this function. Change note: v5: Nothing change. Just rebase on v6.3-rc1. v4: https://lore.kernel.org/linux-mediatek/20230215062544.8677-1-yong.wu@mediatek.com/ Improve the comment in the code from AngeloGioacchino. v3: https://lore.kernel.org/linux-mediatek/20230214031114.926-1-yong.wu@mediatek.com/ Add a new patch only for comment more in the code. v2: https://lore.kernel.org/linux-mediatek/20230208053643.28249-1-yong.wu@mediatek.com/ a) Base on next-20230206 since mt8195 jpeg node is applied which affect this patch. b) Reword the commit message [1/10][2/10] to explain effect. v1: https://lore.kernel.org/linux-mediatek/20230113060133.9394-1-yong.wu@mediatek.com/ Base on v6.2-rc3.
