From: Chen-Yu Tsai Date: Tue, 15 Nov 2022 09:06:44 +0000 (+0800) Subject: arm64: dts: allwinner: h6: Add IOMMU reference to Hantro G2 X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=50edc257a152541b8bcdc84f77de5e4efad7013d;p=linux.git arm64: dts: allwinner: h6: Add IOMMU reference to Hantro G2 The Hantro G2 video decoder block sits behind the IOMMU. Without a reference for the system to properly configure the IOMMU, it will fault and cause the video decoder to fail. Add a proper reference to the IOMMU port. The master ID is taken from the IOMMU fault error message on Linux, and the number seems to match the order in the user manual's IOMMU diagram.
