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 ePAPR).
|
||
|
|
- phy-mode: string, operation mode of the PHY interface; supported values are
|
||
|
|
"mii", "gmii", "sgmii", "qsgmii", "tbi", "rev-mii", "rmii", "rgmii", "rgmii-id",
|
||
|
|
"rgmii-rxid", "rgmii-txid", "rtbi", "smii", "xgmii"; this is now a de-facto
|
||
|
|
standard property;
|
||
|
|
- phy-connection-type: the same as "phy-mode" property but described in ePAPR;
|
||
|
|
- phy-handle: phandle, specifies a reference to a node representing a PHY
|
||
|
|
device; this property is described in ePAPR 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.
|
||
|
|
|
||
|
|
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.
