+USB OHCI controllers
+
+Required properties:
+- compatible : "generic-ohci"
+- reg : ohci controller register range (address and length)
+- interrupts : ohci controller interrupt
+
+Optional properties:
+- big-endian-regs : boolean, set this for hcds with big-endian registers
+- big-endian-desc : boolean, set this for hcds with big-endian descriptors
+- big-endian : boolean, for hcds with big-endian-regs + big-endian-desc
+- no-big-frame-no : boolean, set if frame_no lives in bits [15:0] of HCCA
+- remote-wakeup-connected: remote wakeup is wired on the platform
+- num-ports : u32, to override the detected port count
+- clocks : a list of phandle + clock specifier pairs
+- phys : see usb-hcd.txt in the current directory
+- resets : a list of phandle + reset specifier pairs
+
+additionally the properties from usb-hcd.txt (in the current directory) are
+supported.
+
+Example:
+
+	ohci0: usb@1c14400 {
+		compatible = "allwinner,sun4i-a10-ohci", "generic-ohci";
+		reg = <0x01c14400 0x100>;
+		interrupts = <64>;
+		clocks = <&usb_clk 6>, <&ahb_gates 2>;
+		phys = <&usbphy 1>;
+		phy-names = "usb";
+	};
