1 | The following properties are common to the Ethernet controllers: |
2 | ||
3 | - local-mac-address: array of 6 bytes, specifies the MAC address that was | |
4 | assigned to the network device; | |
5 | - mac-address: array of 6 bytes, specifies the MAC address that was last used by | |
6 | the boot program; should be used in cases where the MAC address assigned to | |
7 | the device by the boot program is different from the "local-mac-address" | |
8 | property; | |
9 | - max-speed: number, specifies maximum speed in Mbit/s supported by the device; | |
10 | - max-frame-size: number, maximum transfer unit (IEEE defined MTU), rather than | |
11 | the maximum frame size (there's contradiction in ePAPR). | |
12 | - phy-mode: string, operation mode of the PHY interface; supported values are | |
b9d12085 | 13 | "mii", "gmii", "sgmii", "qsgmii", "tbi", "rev-mii", "rmii", "rgmii", "rgmii-id", |

14 | "rgmii-rxid", "rgmii-txid", "rtbi", "smii", "xgmii"; this is now a de-facto |
15 | standard property; | |
16 | - phy-connection-type: the same as "phy-mode" property but described in ePAPR; | |
17 | - phy-handle: phandle, specifies a reference to a node representing a PHY | |
18 | device; this property is described in ePAPR and so preferred; | |
19 | - phy: the same as "phy-handle" property, not recommended for new bindings. | |
20 | - phy-device: the same as "phy-handle" property, not recommended for new | |
21 | bindings. | |

23 | Child nodes of the Ethernet controller are typically the individual PHY devices | |
24 | connected via the MDIO bus (sometimes the MDIO bus controller is separate). | |
25 | They are described in the phy.txt file in this same directory. |
