Subject: [PATCH v2 07/10] arm64: dts: mediatek: add smi support for mt8365 SoC
Date: Wed, 05 Apr 2023 10:06:49 +0200	[thread overview]
Message-ID: <20230207-iommu-support-v2-7-60d5fa00e4e5@baylibre.com> (raw)
In-Reply-To: <20230207-iommu-support-v2-0-60d5fa00e4e5@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.
