IOMMU)

v3:

• Split register block in its constituent subblocks, and only require

the ones that the kernel would ever use (Nicolas Frattaroli)

• Group supplies (Rob Herring)
• Explain the way in which the top core is special (Rob Herring)

The base for the series is generally the latest rc1. A different dependency should be noted in *this* patch.

If you already ran 'make dt_binding_check' and didn't see the above error(s), then make sure 'yamllint' is installed and dt-schema is up to date:

pip3 install dtschema --upgrade

Please check and re-submit after running the above command yourself. Note that DT_SCHEMA_FILES can be set to your schema file to speed up checking your schema. However, it must be unset to test all examples with your schema.
