For each -device that exists on this bus, a child node should be created. See -the definition of the PHY node in booting-without-of.txt 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 { - ...... - }; - }; - -* TBI Internal MDIO bus - -As of this writing, every tsec is associated with an internal TBI PHY. -This PHY is accessed through the local MDIO bus. These buses are defined -similarly to the mdio buses, except they are compatible with "fsl,gianfar-tbi". -The TBI PHYs underneath them are similar to normal PHYs, but the reg property -is considered instructive, rather than descriptive. The reg property should -be chosen so it doesn't interfere with other PHYs on the bus. - -* 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. - - bd-stash : If present, indicates that the hardware supports stashing - buffer descriptors in the L2. - - rx-stash-len : Denotes the number of bytes of a received buffer to stash - in the L2. - - rx-stash-idx : Denotes the index of the first byte from the received - buffer to stash in the L2. - -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> - }; |
