Fixing the compatible string typos results in an error in the example:
Documentation/devicetree/bindings/iommu/renesas,ipmmu-vmsa.example.dt.yaml:
iommu@fe951000: 'power-domains' is a required property
Based on the dts files, a 'power-domains' property only exists on Gen 3
which can be conditioned on !renesas,ipmmu-vmsa.
