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	- remote-wakeup-connected: remote wakeup is wired on the platform
14	- num-ports : u32, to override the detected port count
15	- clocks : a list of phandle + clock specifier pairs
16	- phys : phandle + phy specifier pair
17	- phy-names : "usb"
18	- resets : a list of phandle + reset specifier pairs
19	
20	Example:
21	
22		ohci0: usb@01c14400 {
23			compatible = "allwinner,sun4i-a10-ohci", "generic-ohci";
24			reg = <0x01c14400 0x100>;
25			interrupts = <64>;
26			clocks = <&usb_clk 6>, <&ahb_gates 2>;
27			phys = <&usbphy 1>;
28			phy-names = "usb";
29		};
