+OCTEON/OCTEON+ USB BLOCK
+
+1) Main node
+
+   Required properties:
+
+   - compatible: must be "cavium,octeon-5750-usbn"
+
+   - reg: specifies the physical base address of the USBN block and
+     the length of the memory mapped region.
+
+   - #address-cells: specifies the number of cells needed to encode an
+     address. The value must be 2.
+
+   - #size-cells: specifies the number of cells used to represent the size
+     of an address. The value must be 2.
+
+   - ranges: specifies the translation between child address space and parent
+     address space.
+
+   - clock-frequency: speed of the USB reference clock. Allowed values are
+     12000000, 24000000 or 48000000.
+
+   - cavium,refclk-type: type of the USB reference clock. Allowed values are
+     "crystal" or "external".
+
+   - refclk-frequency: deprecated, use "clock-frequency".
+
+   - refclk-type: deprecated, use "cavium,refclk-type".
+
+2) Child node
+
+   The main node must have one child node which describes the built-in
+   USB controller.
+
+   Required properties:
+
+   - compatible: must be "cavium,octeon-5750-usbc"
+
+   - reg: specifies the physical base address of the USBC block and
+     the length of the memory mapped region.
+
+   - interrupts: specifies the interrupt number for the USB controller.
+
+3) Example:
+
+	usbn: usbn@1180068000000 {
+		compatible = "cavium,octeon-5750-usbn";
+		reg = <0x11800 0x68000000 0x0 0x1000>;
+		ranges; /* Direct mapping */
+		#address-cells = <2>;
+		#size-cells = <2>;
+		clock-frequency = <12000000>;
+		cavium,refclk-type = "crystal";
+
+		usbc@16f0010000000 {
+			compatible = "cavium,octeon-5750-usbc";
+			reg = <0x16f00 0x10000000 0x0 0x80000>;
+			interrupts = <0 56>;
+		};
