* 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
|
|
|
|
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
|
|
- local-mac-address : List of bytes representing the ethernet address of
|
|
this controller
|
|
- interrupts : For FEC devices, the first interrupt is the device's
|
|
interrupt. For TSEC and eTSEC devices, the first interrupt is
|
|
transmit, the second is receive, and the third is error.
|
|
- 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.
|
|
- 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.
|
|
- fsl,magic-packet : If present, indicates that the hardware supports
|
|
waking up via magic packet.
|
|
|
|
Example:
|
|
ethernet@24000 {
|
|
device_type = "network";
|
|
model = "TSEC";
|
|
compatible = "gianfar";
|
|
reg = <0x24000 0x1000>;
|
|
local-mac-address = [ 00 E0 0C 00 73 00 ];
|
|
interrupts = <29 2 30 2 34 2>;
|
|
interrupt-parent = <&mpic>;
|
|
phy-handle = <&phy0>
|
|
};
