Since the schema mentions a loader preparing the binding appropriately,
here's a PR with the relevant (WIP) loader code, if anyone wants to look:

My bot found errors running 'make DT_CHECKER_FLAGS=-m dt_binding_check'
on your patch (DT_CHECKER_FLAGS is new in v5.13):

yamllint warnings/errors:

dtschema/dtc warnings/errors:
Documentation/devicetree/bindings/dma/apple,sio.example.dts:24.35-27.11: Warning (node_name_vs_property_name): /example-0/interrupt-controller: node name and property name conflict

This is a quirk with how the examples are constructed. In any case, just 
drop the 'interrupt-controller' node. No need to show providers in an 
example.
