Re: [PATCH 3/20] [powerpc] Remove linux,pci-domain properties

So if I have some device-tree path and want to find the sysfs node
for it or run something like lspci on it, I have to search all of
sysfs for a matching devspec file?  (And this can change each boot.)

Without looking at the mentioned utilities, DLPAR and PCI Hotplug get a 
location code, so I'm hoping that the pci slot name is identified by 
that.  Is lsvpd scanning?  Or does it scan sysfs first and 
/proc/device-tree secondarly?

Yes, lsvpd scans sysfs first, then uses devspec to refer to the device 
tree. and AFAICT, the slot id can't be extracted from the location 
code.

So you're saying that the linux,pci-domain property is still in use, 
right? If so, I'll do up a patch to fix add_linux_pci_domain rather 
than removing it.

Cheers,
