Boris,

First of all, well...
Acked-by: Nicolas Ferre <nicolas.ferre@...el.com>

I didn't find something to add but the little comment about the
documentation that you already fixed in this v3 version.

Mike,

I would like to merge this whole series through my tree and then the
arm-soc tree. If it is okay for you, can you give your acknowledgement
before that I build a pull-request for the arm-soc guys?

Thanks a lot, bye,
