   3 Required properties:
   4         - reg - The ID number for the phy, usually a small integer
   5         - ti,rx-internal-delay - RGMII Receive Clock Delay - see dt-bindings/net/ti-dp83867.h
   6                 for applicable values. Required only if interface type is
   7                 PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_RXID
   8         - ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h
   9                 for applicable values. Required only if interface type is
  10                 PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_TXID
  11         - ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h
  12                 for applicable values
  13
  14 Optional property:
  15         - ti,min-output-impedance - MAC Interface Impedance control to set
  16                                     the programmable output impedance to
  17                                     minimum value (35 ohms).
  18         - ti,max-output-impedance - MAC Interface Impedance control to set
  19                                     the programmable output impedance to
  20                                     maximum value (70 ohms).
  21
  22 Note: ti,min-output-impedance and ti,max-output-impedance are mutually
  23       exclusive. When both properties are present ti,max-output-impedance
  24       takes precedence.
  25
  26 Default child nodes are standard Ethernet PHY device
  27 nodes as described in Documentation/devicetree/bindings/net/phy.txt

  29 Example:
  30
  31         ethernet-phy@0 {
  32                 reg = <0>;
  33                 ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_25_NS>;
  34                 ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;
  35                 ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
  36         };
