+* Cadence MACB/GEM Ethernet controller
+
+Required properties:
+- compatible: Should be "cdns,[<chip>-]{macb|gem}"
+  Use "cdns,at91sam9260-macb" Atmel at91sam9260 and at91sam9263 SoCs.
+  Use "cdns,at32ap7000-macb" for other 10/100 usage or use the generic form: "cdns,macb".
+  Use "cnds,pc302-gem" for Picochip picoXcell pc302 and later devices based on
+  the Cadence GEM, or the generic form: "cdns,gem".
+- reg: Address and length of the register set for the device
+- interrupts: Should contain macb interrupt
+- phy-mode: String, operation mode of the PHY interface.
+  Supported values are: "mii", "rmii", "gmii", "rgmii".
+
+Optional properties:
+- local-mac-address: 6 bytes, mac address
+
+Examples:
+
+        macb0: ethernet@fffc4000 {
+                compatible = "cdns,at32ap7000-macb";
+                reg = <0xfffc4000 0x4000>;
+                interrupts = <21>;
+                phy-mode = "rmii";
+                local-mac-address = [3a 0e 03 04 05 06];
+        };
