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> + }; |
