> Got it. Thanks. In JHB100 I will using "oneOf" 5 clocks or 6 clocks. 7100/7100 are const clock names

No, based on what you did for 'clocks', you just need:

  clock-names:
    minItems: 5
   items:
      - const: stmmaceth
      - const: pclk
      - const: ptp_ref
      - const: tx
      - const: gtx
      - sgmii_rx
