Can you share or specify what patches are needed, are they already
send to upstream ? So people that want to test your series knows what
they need to apply

I think that, at least, this patch is required:

iommu/rockchip: reconstruct to support multi slaves [1]

If this is not already accepted, maybe is a good idea include this
patch in the patch series
