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;
|
||
|
};
