Hi Dan

It probably is not well documented, but one example would be

Documentation/devicetree/bindings/net/ethernet-controller.yaml

says:

      # RX and TX delays are added by the MAC when required
      - rgmii

      # RGMII with internal RX and TX delays provided by the PHY,
      # the MAC should not add the RX or TX delays in this case
      - rgmii-id

      # RGMII with internal RX delay provided by the PHY, the MAC
      # should not add an RX delay in this case
      - rgmii-rxid

      # RGMII with internal TX delay provided by the PHY, the MAC
      # should not add an TX delay in this case

      Andrew
