Oh, I will then drop the SoM's entry as well since the SoM is already defined 
in the carrier boards then. So only

      - description: NetCube Systems Nagami SoM based boards
        items:
          - enum:
              - netcube,nagami-basic-carrier
              - netcube,nagami-keypad-carrier
          - const: netcube,nagami
          - const: allwinner,sun8i-t113s

correct?

Sorry for the back-and-forth, and thanks for your patience.

Best regards,
Lukas
