1* Texas Instruments - dp83867 Giga bit ethernet phy
2
3Required 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
14Optional 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
22Note: 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
26Default child nodes are standard Ethernet PHY device
27nodes as described in Documentation/devicetree/bindings/net/phy.txt
28
29Example:
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 };
