| - 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): |
| compatible = "ibm,usb-ehci-440epx", "usb-ehci"; |
| interrupt-parent = <&UIC0>; |
| reg = <0 e0000300 90 0 e0000390 70>; |
