properties:
  adi,rx-internal-delay-ps:
    description: |
      RGMII RX Clock Delay used only when PHY operates in RGMII mode with
      internal delay (phy-mode is 'rgmii-id' or 'rgmii-rxid') in pico-seconds.
    enum: [ 1600, 1800, 2000, 2200, 2400 ]
    default: 2000

    description: |
      RGMII TX Clock Delay used only when PHY operates in RGMII mode with
      internal delay (phy-mode is 'rgmii-id' or 'rgmii-txid') in pico-seconds.
    enum: [ 1600, 1800, 2000, 2200, 2400 ]
