Quote from the CHRP ISA interrupt controller device binding document: “reserved-interrupts” Standard property name to define reserved interrupts. prop-encoded-array: An integer array, encoded with encode-int. The value of this property shall be a list of ISA interrupts which cannot be assigned due to cascading, wiring, or other reasons. Only the irq# part of the property is pertinent to this use. - End - > > > #address-cells = <1>; > > Why #address-cells set to 1 ?

Yeah, I got them wrong almost everywhere. regards, Gerhard -- GMX FreeMail: 1 GB Postfach, 5 E-Mail-Adressen, 10 Free SMS. Alle Infos und kostenlose Anmeldung: http://www.gmx.net/de/go/freemail
