-USB EHCI controllers
-
-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):
- ehci@e0000300 {
- compatible = "ibm,usb-ehci-440epx", "usb-ehci";
- interrupt-parent = <&UIC0>;
- interrupts = <1a 4>;
- reg = <0 e0000300 90 0 e0000390 70>;
- big-endian;
- };
