"This change fixes a dtbs_check error."
... and introduces new other errors, so error count stays the same. Not
great.

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. Don't rely on
distro packages for dtschema and be sure you are using the latest
released dtschema.

Best regards,
