1USB EHCI controllers
2
3Required 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
11Optional 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 : see usb-hcd.txt in the current directory
20 - resets : phandle + reset specifier pair
21
22additionally the properties from usb-hcd.txt (in the current directory) are
23supported.

25Example (Sequoia 440EPx):
26    ehci@e0000300 {
27	   compatible = "ibm,usb-ehci-440epx", "usb-ehci";
28	   interrupt-parent = <&UIC0>;
29	   interrupts = <1a 4>;
30	   reg = <0 e0000300 90 0 e0000390 70>;
31	   big-endian;
32   };

34Example (Allwinner sun4i A10 SoC):
35   ehci0: usb@1c14000 {
36	   compatible = "allwinner,sun4i-a10-ehci", "generic-ehci";
37	   reg = <0x01c14000 0x100>;
38	   interrupts = <39>;
39	   clocks = <&ahb_gates 1>;
40	   phys = <&usbphy 1>;
41	   phy-names = "usb";
42   };
