Is it a mandatory property? I know we seem to get ugly warnings if it's
missing but I see no mention of it at all in
Documentation/devicetree/bindings/arm/cpus.txt (am I looking in the
wrong place?)

I think this attribute got merged into the kernel with the early power
related scheduling efforts, but given the state of all that at the
moment I was guessing it might be obsolete.
