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



  adi,tx-internal-delay-ps:

    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 ]

    default: 2000



  adi,fifo-depth-bits:

    description: |

      When operating in RMII mode, this option configures the FIFO depth.

    enum: [ 4, 8, 12, 16, 20, 24 ]

    default: 8



  adi,disable-energy-detect:

    description: |

      Disables Energy Detect Powerdown Mode (default disabled, i.e energy detect

      is enabled if this property is unspecified)

    type: boolean



examples:

  - |

    ethernet {

        #address-cells = <1>;

        #size-cells = <0>;



        phy-mode = "rgmii-id";
