Seems an old version got picked up for linux-next:

/builds/robherring/linux-dt/Documentation/devicetree/bindings/firmware/arm,scmi.yaml:
properties:atomic-threshold-us: '$ref' should not be valid under
{'const': '$ref'}
hint: Standard unit suffix properties don't need a type $ref
from schema $id: http://devicetree.org/meta-schemas/core.yaml#
/builds/robherring/linux-dt/Documentation/devicetree/bindings/firmware/arm,scmi.yaml:
ignoring, error in schema: properties: atomic-threshold-us
