* 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 Receive Clock Delay - see dt-bindings/net/ti-dp83867.h
for applicable values. Required only if interface type is
PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_RXID
- ti,tx-internal-delay - RGMII Transmit Clock Delay - see dt-bindings/net/ti-dp83867.h
for applicable values. Required only if interface type is
PHY_INTERFACE_MODE_RGMII_ID or PHY_INTERFACE_MODE_RGMII_TXID
- ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h
for applicable values
Optional property:
- ti,min-output-impedance - MAC Interface Impedance control to set
the programmable output impedance to
minimum value (35 ohms).
- ti,max-output-impedance - MAC Interface Impedance control to set
the programmable output impedance to
maximum value (70 ohms).
Note: ti,min-output-impedance and ti,max-output-impedance are mutually
exclusive. When both properties are present ti,max-output-impedance
takes precedence.
Default child nodes are standard Ethernet PHY device
nodes as described in Documentation/devicetree/bindings/net/phy.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>;
};
