* TSEC-compatible ethernet nodes
|
|
|
|
Properties:
|
|
|
|
- compatible : Should be "fsl,tsec"
|
|
- reg : Offset and length of the register set for the device
|
|
- phy-handle : See ethernet.txt file in the same directory.
|
|
- phy-connection-type : See ethernet.txt file in the same directory. This
|
|
property is only really needed if the connection is of type "rgmii-id",
|
|
"rgmii-rxid" and "rgmii-txid" as all other connection types are detected
|
|
by hardware.
|
|
|
|
Example:
|
|
ethernet@24000 {
|
|
compatible = "fsl,tsec";
|
|
reg = <0x24000 0x1000>;
|
|
phy-handle = <&phy0>;
|
|
phy-connection-type = "sgmii";
|
|
};
|
|
|
|
Child nodes of the TSEC controller are typically the individual PHY devices
|
|
connected via the MDIO bus (sometimes the MDIO bus controller is separate).
|
|
|
|
* MDIO IO device
|
|
|
|
The MDIO is a bus to which the PHY devices are connected. For each
|
|
device that exists on this bus, a PHY node should be created.
|
|
|
|
Required properties:
|
|
- compatible : Should define the compatible device type for the
|
|
mdio. Currently supported string/device is "fsl,tsec-mdio".
|
|
- reg : Offset and length of the register set for the device
|
|
|
|
Example:
|
|
|
|
mdio@24520 {
|
|
compatible = "fsl,tsec-mdio";
|
|
reg = <0x24520 0x20>;
|
|
|
|
ethernet-phy@0 {
|
|
reg = <0>;
|
|
};
|
|
};
