+* OpenCores MAC 10/100 Mbps
+
+Required properties:
+- compatible: Should be "opencores,ethoc".
+- reg: Address and length of the register set for the device and of its
+  descriptor memory.
+- interrupts: Should contain ethoc interrupt.
+
+Optional properties:
+- local-mac-address: 6 bytes, mac address
+- clock-frequency: basic MAC frequency.
+- mii-mgmt-clock-frequency: frequency of MII management bus. Together
+  with clock-frequency determines the value programmed into the CLKDIV
+  field of MIIMODER register.
+
+Examples:
+
+	enet0: ethoc@fd030000 {
+		compatible = "opencores,ethoc";
+		reg = <0xfd030000 0x4000 0xfd800000 0x4000>;
+		interrupts = <1>;
+		local-mac-address = [00 50 c2 13 6f 00];
+		clock-frequency = <50000000>;
+		mii-mgmt-clock-frequency = <5000000>;
+        };
