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

Drop quotes from both lines.

Drop quotes.

Drop oneOf. You do not have more cases here.

Wrong indentation.... kind of expected since you did not test the bindings.
