v3 on the lists, should be final. No, there are no dependencies on 3.13
to the best of my knowledge. The problem with pre-v7 UP systems with
cpus node #address-cells == 0 is still there and I would like to ask you
please what we/I should do about that, it can trigger a considerable
amount of churn. As soon as these bindings hit the mainline I will
update the DT parsing code, I can easily take all pre-v7 UP dts out
of the picture in the parsing loop (after all, reg property for those
processors is useless), but the dts are _wrong_ regardless when these
patches become the official bindings.

Thanks !
Lorenzo
