Alright, so I don't know.

Sure, but that's also _ancient_. There are >12k commits since then that
change arch/arm64/ alone ... And since we didn't change the driver, I
guess the issue is somewhere there?

But ... I see you're one of the NXP ARM64 kernel maintainers so you will
likely know better than me what's going on there :P

I guess you could also check the *virtual* address of the allocated
paged isn't also weirdly unaligned, but either way it's strange that the
arch/iommu/... gives an unaligned physical/IO-virtual address.
