before sending the patchset i did

make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/iio/dac/adi,ad3552r.yaml
  CHKDT   Documentation/devicetree/bindings
  LINT    Documentation/devicetree/bindings
  DTC [C] Documentation/devicetree/bindings/iio/dac/adi,ad3552r.example.dtb

no issues.
