May be I misunderstood.

Most of other bindings related to rzn1d have the both r9a06g032 and
rzn1 compatible string.


Would you expect:

  - a) renesas,r9a06g032-adc and renesas,rzn1-adc

    compatible:
      items:
        - const: renesas,r9a06g032-adc   # RZ/N1D
        - const: renesas,rzn1-adc

or

 - b) renesas,r9a06g032-adc only

    compatible:
      const: renesas,r9a06g032-adc

Can you confirm your expectation?

Best regards,
