* Texas Instruments - dp83867 Giga bit ethernet phy
|
|
|
|
Required properties:
|
|
- reg - The ID number for the phy, usually a small integer
|
|
- ti,rx-internal-delay - RGMII Recieve Clock Delay - see dt-bindings/net/ti-dp83867.h
|
|
for applicable values
|
|
- ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h
|
|
for applicable values
|
|
- ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h
|
|
for applicable values
|
|
|
|
Default child nodes are standard Ethernet PHY device
|
|
nodes as described in doc/devicetree/bindings/net/ethernet.txt
|
|
|
|
Example:
|
|
|
|
ethernet-phy@0 {
|
|
reg = <0>;
|
|
ti,rx-internal-delay = <DP83867_RGMIIDCTL_2_25_NS>;
|
|
ti,tx-internal-delay = <DP83867_RGMIIDCTL_2_75_NS>;
|
|
ti,fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
|
|
};
