Subject: [PATCH v3 1/3] dt-bindings: iommu: dart: Add t8103-usb4-dart compatible
Date: Sat, 11 Mar 2023 14:38:54 +0100 [thread overview]
Message-ID: <20230311133856.63840-2-sven@svenpeter.dev> (raw)
In-Reply-To: <20230311133856.63840-1-sven@svenpeter.dev>
This DART variant is found in the t8103 (M1) SoCs and used for the
USB4/Thunderbolt PCIe ports. Unlike the regular t8103 DART these support
up to 64 SIDs and require a slightly different MMIO layout.
