5 the definition of the PHY node in booting-without-of.txt for an example
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";

28 similarly to the mdio buses, except they are compatible with "fsl,gianfar-tbi".
33 * Gianfar-compatible ethernet nodes
37   - device_type : Should be "network"
38   - model : Model of the device.  Can be "TSEC", "eTSEC", or "FEC"
39   - compatible : Should be "gianfar"
40   - reg : Offset and length of the register set for the device
41   - local-mac-address : List of bytes representing the ethernet address of
43   - interrupts : For FEC devices, the first interrupt is the device's
46   - phy-handle : The phandle for the PHY connected to this ethernet
48   - fixed-link : <a b c d e> where a is emulated phy id - choose any,
49     but unique to the all specified fixed-links, b is duplex - 0 half,
50     1 full, c is link speed - d#10/d#100/d#1000, d is pause - 0 no
51     pause, 1 pause, e is asym_pause - 0 no asym_pause, 1 asym_pause.
52   - phy-connection-type : a string naming the controller/PHY interface type,
53     i.e., "mii" (default), "rmii", "gmii", "rgmii", "rgmii-id", "sgmii",
55     is of type "rgmii-id", as all other connection types are detected by
57   - fsl,magic-packet : If present, indicates that the hardware supports
59   - bd-stash : If present, indicates that the hardware supports stashing
61   - rx-stash-len : Denotes the number of bytes of a received buffer to stash
63   - rx-stash-idx : Denotes the index of the first byte from the received

78 * Gianfar PTP clock nodes
82   - compatible   Should be "fsl,etsec-ptp"
83   - reg          Offset and length of the register set for the device
84   - interrupts   There should be at least two interrupts. Some devices
87 Clock Properties:
89   - fsl,tclk-period  Timer reference clock period in nanoseconds.
90   - fsl,tmr-prsc     Prescaler, divides the output clock.
91   - fsl,tmr-add      Frequency compensation value.
92   - fsl,tmr-fiper1   Fixed interval period pulse generator.
93   - fsl,tmr-fiper2   Fixed interval period pulse generator.
94   - fsl,max-adj      Maximum frequency adjustment in parts per billion.
