1 * Texas Instruments - dp83867 Giga bit ethernet phy
2
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
7         - ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h
8                 for applicable values
9         - ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h
10                 for applicable values
11
12 Optional property:
13         - ti,min-output-impedance - MAC Interface Impedance control to set
14                                     the programmable output impedance to
15                                     minimum value (35 ohms).
16         - ti,max-output-impedance - MAC Interface Impedance control to set
17                                     the programmable output impedance to
18                                     maximum value (70 ohms).
19
20 Note: ti,min-output-impedance and ti,max-output-impedance are mutually
21       exclusive. When both properties are present ti,max-output-impedance
22       takes precedence.
23
24 Default child nodes are standard Ethernet PHY device
25 nodes as described in Documentation/devicetree/bindings/net/phy.txt

27 Example:
28
29         ethernet-phy@0 {
30                 reg = <0>;
31                 ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_25_NS>;
32                 ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;
33                 ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
34         };
