arm64: dts: allwinner: h6: Fix Cedrus IOMMU usage
Now that the IOMMU driver has been introduced, it prevents any access from a DMA master going through it that hasn't properly mapped the pages, and that link is set up through the iommus property. Unfortunately we forgot to add that property to the video engine node when adding the IOMMU node, so now any DMA access is broken. Fixes: b3a0a2f910c7 ("arm64: dts: allwinner: h6: Add IOMMU") Signed-off-by: Maxime Ripard <maxime@cerno.tech> Link: https://lore.kernel.org/r/20200628180804.79026-1-maxime@cerno.tech
