1	USB OHCI controllers
2	
3	Required properties:
4	- compatible : "generic-ohci"
5	- reg : ohci controller register range (address and length)
6	- interrupts : ohci controller interrupt
7	
8	Optional properties:
9	- big-endian-regs : boolean, set this for hcds with big-endian registers
10	- big-endian-desc : boolean, set this for hcds with big-endian descriptors
11	- big-endian : boolean, for hcds with big-endian-regs + big-endian-desc
12	- no-big-frame-no : boolean, set if frame_no lives in bits [15:0] of HCCA
13	- num-ports : u32, to override the detected port count
14	- clocks : a list of phandle + clock specifier pairs
15	- phys : phandle + phy specifier pair
16	- phy-names : "usb"
17	- resets : phandle + reset specifier pair
18	
19	Example:
20	
21		ohci0: usb@01c14400 {
22			compatible = "allwinner,sun4i-a10-ohci", "generic-ohci";
23			reg = <0x01c14400 0x100>;
24			interrupts = <64>;
25			clocks = <&usb_clk 6>, <&ahb_gates 2>;
26			phys = <&usbphy 1>;
27			phy-names = "usb";
28		};
