Thank you for this report.  After upgrading the "dtschema" package I
also see these errors.  The "gpio" and "ethernet" properties will
have an "unevaluatedProperties: false" constraint added in the next
version of this series.  The name of the binding file will also be
correct in the MAINTAINERS file.
