-* 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
-
-Note: If the interface type is PHY_INTERFACE_MODE_RGMII the TX/RX clock delays
- will be left at their default values, as set by the PHY's pin strapping.
- The default strapping will use a delay of 2.00 ns. Thus
- PHY_INTERFACE_MODE_RGMII, by default, does not behave as RGMII with no
- internal delay, but as PHY_INTERFACE_MODE_RGMII_ID. The device tree
- should use "rgmii-id" if internal delays are desired as this may be
- changed in future to cause "rgmii" mode to disable delays.
-
-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).
- - ti,dp83867-rxctrl-strap-quirk - This denotes the fact that the
- board has RX_DV/RX_CTRL pin strapped in
- mode 1 or 2. To ensure PHY operation,
- there are specific actions that
- software needs to take when this pin is
- strapped in these modes. See data manual
- for details.
- - ti,clk-output-sel - Muxing option for CLK_OUT pin. See dt-bindings/net/ti-dp83867.h
- for applicable values. The CLK_OUT pin can also
- be disabled by this property. When omitted, the
- PHY's default will be left as is.
- - ti,sgmii-ref-clock-output-enable - This denotes which
- SGMII configuration is used (4 or 6-wire modes).
- Some MACs work with differential SGMII clock.
- See data manual for details.
-
- - ti,fifo-depth - Transmitt FIFO depth- see dt-bindings/net/ti-dp83867.h
- for applicable values (deprecated)
-
- -tx-fifo-depth - As defined in the ethernet-controller.yaml. Values for
- the depth can be found in dt-bindings/net/ti-dp83867.h
- -rx-fifo-depth - As defined in the ethernet-controller.yaml. Values for
- the depth can be found in dt-bindings/net/ti-dp83867.h
-
-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>;
- tx-fifo-depth = <DP83867_PHYCR_FIFO_DEPTH_4_B_NIB>;
- };
