Why this is a simple MFD without children? Something is not right here.
Either this is not simple-mfd or this is not complete binding.

It does not look like you tested the bindings, at least after quick
look. Please run `make dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
Maybe you need to update your dtschema and yamllint.

Krzysztof
