And remove dependencies on CONFIG_EXPERT.
In order to help to make the decision, can you provide the following
information:
- Is it functionally complete?
- Can it work on all known platforms with IPMMU VMSA?
- Is there any plan to smoke (manually or automatically) test the
driver?

Not entirely directed to the IPMMU-VMSA. Passthrough is not security
supported on Arm today, so it is a bit odd to make the IOMMU drivers
security supported.
I am thinking to downgrade the ARM SMMUv{1, 2} to "supported, not
security supported" to avoid any confusion if a potential security issue
arise.
Stefano, what do you think?
