1	USB EHCI controllers
2	
3	Required properties:
4	  - compatible : should be "generic-ehci".
5	  - reg : should contain at least address and length of the standard EHCI
6	    register set for the device. Optional platform-dependent registers
7	    (debug-port or other) can be also specified here, but only after
8	    definition of standard EHCI registers.
9	  - interrupts : one EHCI interrupt should be described here.
10	
11	Optional properties:
12	 - big-endian-regs : boolean, set this for hcds with big-endian registers
13	 - big-endian-desc : boolean, set this for hcds with big-endian descriptors
14	 - big-endian : boolean, for hcds with big-endian-regs + big-endian-desc
15	 - needs-reset-on-resume : boolean, set this to force EHCI reset after resume
16	 - has-transaction-translator : boolean, set this if EHCI have a Transaction
17					Translator built into the root hub.
18	 - clocks : a list of phandle + clock specifier pairs
19	 - phys : phandle + phy specifier pair
20	 - phy-names : "usb"
21	 - resets : phandle + reset specifier pair
22	
23	Example (Sequoia 440EPx):
24	    ehci@e0000300 {
25		   compatible = "ibm,usb-ehci-440epx", "usb-ehci";
26		   interrupt-parent = <&UIC0>;
27		   interrupts = <1a 4>;
28		   reg = <0 e0000300 90 0 e0000390 70>;
29		   big-endian;
30	   };
31	
32	Example (Allwinner sun4i A10 SoC):
33	   ehci0: usb@01c14000 {
34		   compatible = "allwinner,sun4i-a10-ehci", "generic-ehci";
35		   reg = <0x01c14000 0x100>;
36		   interrupts = <39>;
37		   clocks = <&ahb_gates 1>;
38		   phys = <&usbphy 1>;
39		   phy-names = "usb";
40	   };
