Anyone know the origin of the #cpus property that seems to be in most of
the DTS files. It seems to be documented nowhere.
It's obviously describing how many cpus exist. However, greping the
kernel source turns up no references to it.
Is it supposed to be required for all cpus nodes? Are there plans to
actually use it?

It was there in the first DTS file to hit the kernel
source tree. Probably all others just copied that.

It is utterly redundant as simply looking at the number
of child nodes of /cpus/ will tell you the same thing.
Well *hopefully* the same thing, heh.

That sounds likely. We should probably get rid of it, the kernel
doesn't use it. BenH, Paulus, you can't see any use for this one?

Nope.
