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.
