1USB EHCI controllers
2
3Required properties:
4 - compatible : should be "usb-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.
10If device registers are implemented in big endian mode, the device
11node should have "big-endian-regs" property.
12If controller implementation operates with big endian descriptors,
13"big-endian-desc" property should be specified.
14If both big endian registers and descriptors are used by the controller
15implementation, "big-endian" property can be specified instead of having
16both "big-endian-regs" and "big-endian-desc".

18Example (Sequoia 440EPx):
19 ehci@e0000300 {
20 compatible = "ibm,usb-ehci-440epx", "usb-ehci";
21 interrupt-parent = <&UIC0>;
22 interrupts = <1a 4>;
23 reg = <0 e0000300 90 0 e0000390 70>;
24 big-endian;
25 };
