1*7b9cf840SSimon GlassThe following properties are common to the Ethernet controllers: 2*7b9cf840SSimon Glass 3*7b9cf840SSimon Glass- local-mac-address: array of 6 bytes, specifies the MAC address that was 4*7b9cf840SSimon Glass assigned to the network device; 5*7b9cf840SSimon Glass- mac-address: array of 6 bytes, specifies the MAC address that was last used by 6*7b9cf840SSimon Glass the boot program; should be used in cases where the MAC address assigned to 7*7b9cf840SSimon Glass the device by the boot program is different from the "local-mac-address" 8*7b9cf840SSimon Glass property; 9*7b9cf840SSimon Glass- max-speed: number, specifies maximum speed in Mbit/s supported by the device; 10*7b9cf840SSimon Glass- max-frame-size: number, maximum transfer unit (IEEE defined MTU), rather than 11*7b9cf840SSimon Glass the maximum frame size (there's contradiction in ePAPR). 12*7b9cf840SSimon Glass- phy-mode: string, operation mode of the PHY interface; supported values are 13*7b9cf840SSimon Glass "mii", "gmii", "sgmii", "qsgmii", "tbi", "rev-mii", "rmii", "rgmii", "rgmii-id", 14*7b9cf840SSimon Glass "rgmii-rxid", "rgmii-txid", "rtbi", "smii", "xgmii"; this is now a de-facto 15*7b9cf840SSimon Glass standard property; 16*7b9cf840SSimon Glass- phy-connection-type: the same as "phy-mode" property but described in ePAPR; 17*7b9cf840SSimon Glass- phy-handle: phandle, specifies a reference to a node representing a PHY 18*7b9cf840SSimon Glass device; this property is described in ePAPR and so preferred; 19*7b9cf840SSimon Glass- phy: the same as "phy-handle" property, not recommended for new bindings. 20*7b9cf840SSimon Glass- phy-device: the same as "phy-handle" property, not recommended for new 21*7b9cf840SSimon Glass bindings. 22*7b9cf840SSimon Glass 23*7b9cf840SSimon GlassChild nodes of the Ethernet controller are typically the individual PHY devices 24*7b9cf840SSimon Glassconnected via the MDIO bus (sometimes the MDIO bus controller is separate). 25*7b9cf840SSimon GlassThey are described in the phy.txt file in this same directory. 26
