Yeah, PCI is a special case for Linux.  Maybe add a "pciclass,XXXX"
compatible property though, for good measure.  Anything else isn't
all that useful I think.

Wouldn't that be the same as the class-code property?

Indeed, since PCI is probable, it's unclear whether these device nodes
are even necessary at all.  Depends on whether there's anything
interesting in the omitted interrupt routing information.

Well, I mainly specified the device node for the IDE controller, because
it works in compatible mode and thus the IDE driver needs to know about
the I/O ports. I guess the driver doesn't probe the BARs, if the
controller is configured for compatible mode (and AFAIK a VIA IDE
controller cannot be made work in fully native mode). Also the ppc_ide_md
function hooks are considered obsolete.
The interrupts for the IDE controller are another story. Judging from
what some developers wrote on this mailing list, there doesn't seem to
be a way to define legacy IDE interrupts (14 & 15) for a PCI device node.
Therefore I'll reuse the IDE interrupt quirk for the Pegasos.
