BTW, I think the fix is going to be just the new 'unevaluatedProperties: false'.

The Allwinner SoCs have an interrupt controller supported in Linux, with a matching Device Tree binding. Now that we have the DT validation in place, let's convert the device tree bindings for that controller over to a YAML schemas.
