The main DRM device is actually a virtual device so it doesn't have the iommus property, which is instead on the DMA masters, in this case the mixers.
The iommu driver and DT changes were added in v5.8-rc1. IMO There is no point in backporting this patch to any stable kernel.
Now dropped from everywhere, thanks.
