[PATCH v5 5/7] arm64: dts: mediatek: add smi support for mt8365 SoC

From: Alexandre Mergnat
Date: Thu Sep 21 2023 - 16:11:44 EST


Smart Multimedia Interface (SMI) local arbiter does the arbitration for
memory requests from multi-media engines. Add SMI in the MT8365 DTS will
allow to add local ARBiter (LARB), use by IOMMU.
