Agreed.

I know you're a bit distracted currently ;) but is there any chance you
can refresh at least this patch:

    OMAP3+: PM: VP: use uV for max and min voltage limits

from your series on top of my current pm-wip/voltdm branch?

If not, maybe point us to an archived version and Tero can pick it up
and add it to this series.  After a quick search, I couldn't find it in
the marc.info archives.

Thanks,

Kevin
