This patch provides the documentation of the device bindings for the AMD 10GbE platform driver.

You can also reference ethernet.txt and phy.txt in the same directory for details about 'phy-handle'. 'phy-mode' is also a required property here since you have specified a 'phy-handle' phandle to the PHY node.

+Optional properties:
+- mac-address: mac address to be assigned to the device. Can be overridden
+ by UEFI.
