OK, v5 looks good to me.   One more minor minor detail.  Can you post
one more time with linux-arm-kernel in Cc so it doesn't have to be
reposted before Tony merges it.  Please also add in Paul's ack on patch
3.  Thanks.

Unless there are other objections, I'll pull the next rev into my
pm-next and queue for 2.6.38.

Note that as we go further with DVFS, we will likely need to expand this
OPP data/table to include some more options, but that can be done when
the time comes, so I'm OK with the current form for now.

Thanks Nishanth,

Kevin
