Hello !

These patches rework the ibmpowernv driver to support the new device 
tree as proposed by this patchset on the skiboot mailing list :

  https://lists.ozlabs.org/pipermail/skiboot/2015-February/000457.html

They are based on Linux 3.19 and were tested on IBM Power and Open Power 
systems running trusty.

The main issue is that the new device tree is incompatible with the 
previous ibmpowernv drivers. The consequence is no powernv sensors 
on systems with such a opal/linux configuration.

I don't think that would be acceptable. There must be lots of such
systems out there. Why does it have to be incompatible ?
Can't it support both the old and new versions ?
