Drop all these 7, especially that input-enable is not allowed explicitly.

Instead:
unevaluatedProperties: false
and put it after the $ref above. Just like recent changes in the next.

Does not look like you tested the bindings. Please run `make
dt_binding_check` (see
Documentation/devicetree/bindings/writing-schema.rst for instructions).
