I think the canonical name for an IOMMU device is 'iommu', not 'smmu'.

Better avoid underscores in strings, and drop the "_clk" postfix in
the clock names.

I did not receive patch 1/3 this time, but I see in version 1, that
you forgot to document the strings:

This needs to list the names of the clock inputs to the smmu.
