Subject: [PATCH 5/5] arm64: dts: allwinner: h616: add IOMMU node
Date: Fri, 31 May 2024 00:38:00 +0100 [thread overview]
Message-ID: <20240530233800.27705-6-andre.przywara@arm.com> (raw)
In-Reply-To: <20240530233800.27705-1-andre.przywara@arm.com>
The Allwinner H616 contains a scatter-gather IOMMU connected to some
video related devices. It's almost compatible to the one used in the H6,
though with minor incompatibilities.
Add the DT node describing its resources, so that devices like the video
or display engine can connect to it.
