With the new revision the standalone 'compatible = "qcom,pmi632-vib";'
doesn't pass validation anymore.

foo.dtb: vibrator@...0: compatible: 'oneOf' conditional failed, one must be fixed:
        ['qcom,pmi632-vib'] is too short
        'qcom,pmi632-vib' is not one of ['qcom,pm8058-vib', 'qcom,pm8916-vib', 'qcom,pm8921-vib']
        'qcom,pmi632-vib' is not one of ['qcom,pm7250b-vib', 'qcom,pm7325b-vib', 'qcom,pm7550ba-vib']
        from schema $id: http://devicetree.org/schemas/input/qcom,pm8xxx-vib.yaml#

I believe you need to add the compatible also like this:
