For the -generic PHY 'phys' property, see -Documentation/devicetree/bindings/phy/phy-bindings.txt. - -- mac-address: array of 6 bytes, specifies the MAC address that was last used by - the boot program; should be used in cases where the MAC address assigned to - the device by the boot program is different from the "local-mac-address" - property; -- local-mac-address: array of 6 bytes, specifies the MAC address that was - assigned to the network device; -- nvmem-cells: phandle, reference to an nvmem node for the MAC address -- nvmem-cell-names: string, should be "mac-address" if nvmem is to be used -- max-speed: number, specifies maximum speed in Mbit/s supported by the device; -- max-frame-size: number, maximum transfer unit (IEEE defined MTU), rather than - the maximum frame size (there's contradiction in the Devicetree - Specification). -- phy-mode: string, operation mode of the PHY interface. This is now a de-facto - standard property; supported values are: - * "internal" (Internal means there is not a standard bus between the MAC and - the PHY, something proprietary is being used to embed the PHY in the MAC.) - * "mii" - * "gmii" - * "sgmii" - * "qsgmii" - * "tbi" - * "rev-mii" - * "rmii" - * "rgmii" (RX and TX delays are added by the MAC when required) - * "rgmii-id" (RGMII with internal RX and TX delays provided by the PHY, the - MAC should not add the RX or TX delays in this case) - * "rgmii-rxid" (RGMII with internal RX delay provided by the PHY, the MAC - should not add an RX delay in this case) - * "rgmii-txid" (RGMII with internal TX delay provided by the PHY, the MAC - should not add an TX delay in this case) - * "rtbi" - * "smii" - * "xgmii" - * "trgmii" - * "1000base-x", - * "2500base-x", - * "rxaui" - * "xaui" - * "10gbase-kr" (10GBASE-KR, XFI, SFI) -- phy-connection-type: the same as "phy-mode" property but described in the - Devicetree Specification; -- phy-handle: phandle, specifies a reference to a node representing a PHY - device; this property is described in the Devicetree Specification and so - preferred; -- phy: the same as "phy-handle" property, not recommended for new bindings. -- phy-device: the same as "phy-handle" property, not recommended for new - bindings. -- rx-fifo-depth: the size of the controller's receive fifo in bytes. This - is used for components that can have configurable receive fifo sizes, - and is useful for determining certain configuration settings such as - flow control thresholds. -- tx-fifo-depth: the size of the controller's transmit fifo in bytes. This - is used for components that can have configurable fifo sizes. -- managed: string, specifies the PHY management type. Supported values are: - "auto", "in-band-status". "auto" is the default, it usess MDIO for - management if fixed-link is not specified. - -Child nodes of the Ethernet controller are typically the individual PHY devices -connected via the MDIO bus (sometimes the MDIO bus controller is separate). -They are described in the phy.txt file in this same directory. -For non-MDIO PHY management see fixed-link.txt. +This file has moved to ethernet-controller.yaml. |
