Subject: [PATCH v5 5/7] arm64: dts: mediatek: add smi support for mt8365 SoC
Date: Thu, 21 Sep 2023 16:32:44 +0200	[thread overview]
Message-ID: <20230207-iommu-support-v5-5-fa6f03680832@baylibre.com> (raw)
In-Reply-To: <20230207-iommu-support-v5-0-fa6f03680832@baylibre.com>

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.
