| * MDIO IO device |
| |
| The MDIO is a bus to which the PHY devices are connected. For each |
| device that exists on this bus, a child node should be created. See |
| the definition of the PHY node below for an example of how to define |
| a PHY. |
| |
| Required properties: |
| - reg : Offset and length of the register set for the device |
| - compatible : Should define the compatible device type for the |
| mdio. Currently, this is most likely to be "fsl,gianfar-mdio" |
| |
| Example: |
| |
| mdio@24520 { |
| reg = <24520 20>; |
| compatible = "fsl,gianfar-mdio"; |
| |
| ethernet-phy@0 { |
| ...... |
| }; |
| }; |
| |
| |
| * Gianfar-compatible ethernet nodes |
| |
| Required properties: |
| |
| - device_type : Should be "network" |
| - model : Model of the device. Can be "TSEC", "eTSEC", or "FEC" |
| - compatible : Should be "gianfar" |
| - reg : Offset and length of the register set for the device |
| - mac-address : List of bytes representing the ethernet address of |
| this controller |
| - interrupts : <a b> where a is the interrupt number and b is a |
| field that represents an encoding of the sense and level |
| information for the interrupt. This should be encoded based on |
| the information in section 2) depending on the type of interrupt |
| controller you have. |
| - interrupt-parent : the phandle for the interrupt controller that |
| services interrupts for this device. |
| - phy-handle : The phandle for the PHY connected to this ethernet |
| controller. |
| - fixed-link : <a b c d e> where a is emulated phy id - choose any, |
| but unique to the all specified fixed-links, b is duplex - 0 half, |
| 1 full, c is link speed - d#10/d#100/d#1000, d is pause - 0 no |
| pause, 1 pause, e is asym_pause - 0 no asym_pause, 1 asym_pause. |
| |
| Recommended properties: |
| |
| - phy-connection-type : a string naming the controller/PHY interface type, |
| i.e., "mii" (default), "rmii", "gmii", "rgmii", "rgmii-id", "sgmii", |
| "tbi", or "rtbi". This property is only really needed if the connection |
| is of type "rgmii-id", as all other connection types are detected by |
| hardware. |
| |
| |
| Example: |
| ethernet@24000 { |
| #size-cells = <0>; |
| device_type = "network"; |
| model = "TSEC"; |
| compatible = "gianfar"; |
| reg = <24000 1000>; |
| mac-address = [ 00 E0 0C 00 73 00 ]; |
| interrupts = <d 3 e 3 12 3>; |
| interrupt-parent = <40000>; |
| phy-handle = <2452000> |
| }; |
