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.

There is no way this would work and if you test you will see error msg.
Feel free to ping if message is unclear.

It's not oneOf. Just enum

Are you sure these are compatible devices then? What does it mean "not
needed"? Is the pin there or is not?

NAK. Really. Test patches before sending.
