| * 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). |
| - 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. |
| |
| 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>; |
| }; |
