3 The MDIO is a bus to which the PHY devices are connected. For each
4 device that exists on this bus, a child node should be created. See
5 the definition of the PHY node below for an example of how to define
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"
17 compatible = "fsl,gianfar-mdio";
25 * Gianfar-compatible ethernet nodes
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
33 - local-mac-address : List of bytes representing the ethernet address of
35 - 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.
38 - phy-handle : The phandle for the PHY connected to this ethernet
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.
44 - 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
49 - fsl,magic-packet : If present, indicates that the hardware supports
50 waking up via magic packet.
