From 0c85e2e377c368e1e0f04ea28dcbc5aa06302551 Mon Sep 17 00:00:00 2001 From: Andre Przywara Date: Sun, 16 Jun 2024 23:40:56 +0100 Subject: [PATCH] arm64: dts: allwinner: h616: add IOMMU node 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.
