Kumar Galad0fc2ea2008-07-07 11:28:33 -05001* MDIO IO device
2
3The MDIO is a bus to which the PHY devices are connected. For each
4device that exists on this bus, a child node should be created. See
5the definition of the PHY node below for an example of how to define
6a PHY.
7
8Required properties:
9 - reg : Offset and length of the register set for the device
10 - compatible : Should define the compatible device type for the
11 mdio. Currently, this is most likely to be "fsl,gianfar-mdio"
12
13Example:
14
15 mdio@24520 {
16 reg = <24520 20>;
17 compatible = "fsl,gianfar-mdio";
18
19 ethernet-phy@0 {
20 ......
21 };
22 };

Scott Wood00262982008-07-11 18:04:43 -050027Properties:
Kumar Galad0fc2ea2008-07-07 11:28:33 -050028
29 - device_type : Should be "network"
30 - model : Model of the device. Can be "TSEC", "eTSEC", or "FEC"
31 - compatible : Should be "gianfar"
32 - reg : Offset and length of the register set for the device
Scott Wood00262982008-07-11 18:04:43 -050033 - local-mac-address : List of bytes representing the ethernet address of
Kumar Galad0fc2ea2008-07-07 11:28:33 -050034 this controller
Scott Wood00262982008-07-11 18:04:43 -050035 - interrupts : For FEC devices, the first interrupt is the device's
36 interrupt. For TSEC and eTSEC devices, the first interrupt is
37 transmit, the second is receive, and the third is error.
Kumar Galad0fc2ea2008-07-07 11:28:33 -050038 - phy-handle : The phandle for the PHY connected to this ethernet
39 controller.
40 - fixed-link : <a b c d e> where a is emulated phy id - choose any,
41 but unique to the all specified fixed-links, b is duplex - 0 half,
42 1 full, c is link speed - d#10/d#100/d#1000, d is pause - 0 no
43 pause, 1 pause, e is asym_pause - 0 no asym_pause, 1 asym_pause.
Kumar Galad0fc2ea2008-07-07 11:28:33 -050044 - phy-connection-type : a string naming the controller/PHY interface type,
45 i.e., "mii" (default), "rmii", "gmii", "rgmii", "rgmii-id", "sgmii",
46 "tbi", or "rtbi". This property is only really needed if the connection
47 is of type "rgmii-id", as all other connection types are detected by
48 hardware.
Scott Wood00262982008-07-11 18:04:43 -050049 - fsl,magic-packet : If present, indicates that the hardware supports
50 waking up via magic packet.
