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, and optionally - the offset and length of the TBIPA register (TBI PHY address - register). If TBIPA register is not specified, the driver will - attempt to infer it from the register set specified (your mileage may - vary). - - compatible : Should define the compatible device type for the - mdio. Currently supported strings/devices are: - - "fsl,gianfar-tbi" - - "fsl,gianfar-mdio" - - "fsl,etsec2-tbi" - - "fsl,etsec2-mdio" - - "fsl,ucc-mdio" - - "fsl,fman-mdio" - When device_type is "mdio", the following strings are also considered: - - "gianfar" - - "ucc_geth_phy" - -Example: - - mdio@24520 { - reg = <24520 20>; - compatible = "fsl,gianfar-mdio"; - - ethernet-phy@0 { - ...... - }; - }; +Refer to Documentation/devicetree/bindings/net/fsl,gianfar-mdio.yaml * 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. +Refer to Documentation/devicetree/bindings/net/fsl,gianfar-mdio.yaml * 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 - - 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 : See ethernet.txt file in the same directory. - - fixed-link : See fixed-link.txt in the same directory. - - phy-connection-type : See ethernet.txt file in the same directory. - 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. - - fsl,wake-on-filer : If present, indicates that the hardware supports - waking up by Filer General Purpose Interrupt (FGPI) asserted on the - Rx int line. This is an advanced power management capability allowing - certain packet types (user) defined by filer rules to wake up the system. - - 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> - }; +Refer to Documentation/devicetree/bindings/net/fsl,gianfar.yaml * Gianfar PTP clock nodes -Refer to Documentation/devicetree/bindings/ptp/ptp-qoriq.txt +Refer to Documentation/devicetree/bindings/ptp/fsl,ptp.yaml |
