+ Required properties:
+ - compatible : should be "usb-ehci".
+ - reg : should contain at least address and length of the standard EHCI
+ register set for the device. Optional platform-dependent registers
+ (debug-port or other) can be also specified here, but only after
+ definition of standard EHCI registers.
+ - interrupts : one EHCI interrupt should be described here.
+ If device registers are implemented in big endian mode, the device
+ node should have "big-endian-regs" property.
+ If controller implementation operates with big endian descriptors,
+ "big-endian-desc" property should be specified.
+ If both big endian registers and descriptors are used by the controller
+ implementation, "big-endian" property can be specified instead of having
+ both "big-endian-regs" and "big-endian-desc".
+
+ Example (Sequoia 440EPx):
+ [EMAIL PROTECTED] {
+ compatible = "ibm,usb-ehci-440epx", "usb-ehci";
+ interrupt-parent = <&UIC0>;
+ interrupts = <1a 4>;
+ reg = <0 e0000300 90 0 e0000390 70>;
+ big-endian;

More devices will be defined as this spec matures.
