The following properties are common to the Ethernet controllers:
|
|
|
|
- local-mac-address: array of 6 bytes, specifies the MAC address that was
|
|
assigned to the network device;
|
|
- 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;
|
|
- 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"
|
|
* "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"
|
|
* "2000base-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.
