The reference binding doc is from:
|

http://www.devicetree.org/open-firmware/bindings/usb/usb-1_0.ps
|
||||
|
||||
|

Required properties:
|
||||
- compatible: usbVID,PID. The textual representation of VID, PID shall
|
||||
be in lower case hexadecimal with leading zeroes suppressed. The
|
||||
other compatible strings from the above standard binding could also
|
||||
be used, but a device adhering to this binding may leave out all except
|
||||
for usbVID,PID.
|
||||
- reg: the port number which this device is connecting to, the range
|
||||
is 1-31.
|
||||
- compatible: "usbVID,PID", where VID is the vendor id and PID the product id.
|
||||
The textual representation of VID and PID shall be in lower case hexadecimal
|
||||
with leading zeroes suppressed. The other compatible strings from the above
|
||||
standard binding could also be used, but a device adhering to this binding
|
||||
may leave out all except for "usbVID,PID".

- reg: the number of the USB hub port or the USB host-controller port to which
|
||||
this device is attached. The range is 1-255.
|

Required properties for hub nodes with device nodes:
|

- #address-cells: shall be 1
|

- #size-cells: shall be 0
|

Required properties for host-controller nodes with device nodes:
