Subject: [PATCH 1/4] dt-bindings: iommu: dart: Add t8103-usb4-dart compatible
Date: Sat, 28 Jan 2023 12:11:11 +0100 [thread overview]
Message-ID: <20230128111114.4049-2-sven@svenpeter.dev> (raw)
In-Reply-To: <20230128111114.4049-1-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. This variant
is only found on the M1 SoCs.
