Subject: [PATCH v3 4/8] arm64: dts: mediatek: mt8188: Add SMI/LARB/IOMMU support
Local Arbiter (LARB) is a component of Smart Multimedia Interface (SMI)
that supports IOMMU on the MediaTek SoCs.
Add the following nodes for memory management support on MT8188 SoC:
- one Infra IOMMU
- two Multimedia (MM) IOMMUs of VDO and VPP
- corresponding SMI common and LARB nodes of the MM IOMMUs
Signed-off-by: Fei Shao <fshao@...omium.org>
