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

  18 Example (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    };
