+* Common Ethernet Interface (BGX) block
+
+Properties:
+
+- compatible: "cavium,octeon-7890-bgx": Compatibility with all cn7xxx SOCs.
+
+- reg: The base address of the BGX block.
+
+- #address-cells: Must be <1>.
+
+- #size-cells: Must be <0>.  BGX addresses have no size component.
+
+A BGX block has several children, each representing an Ethernet
+interface.
+
+
+* Ethernet Interface (BGX port) connects to PKI/PKO
+
+Properties:
+
+- compatible: "cavium,octeon-7890-bgx-port": Compatibility with all
+             cn7xxx SOCs.
+
+             "cavium,octeon-7360-xcv": Compatibility with cn73xx SOCs
+             for RGMII.
+
+- reg: The index of the interface within the BGX block.
+
+Optional properties:
+
+- local-mac-address: Mac address for the interface.
+
+- phy-handle: phandle to the phy node connected to the interface.
+
+- phy-mode: described in ethernet.txt.
+
+- fixed-link: described in fixed-link.txt.
+
+Example:
+
