The correct file is regulator.yaml.

That's indicated by this warning:

schemas/regulator/regulators.yaml: ignoring, error parsing file

It will fail worse than that once the example in the MFD file is added.

Lee, Mark, I've said it before, but MFD plus child schemas need to be
applied together. Maybe no one cares if dt_binding_check is broken on
the MFD tree. The primary issue for me is transient failures during
the merge window.
