PM branch updated

FYI...

I just pushed an updated PM branch which was rebased to current omap/master (which is based on v2.6.31-rc5)

This includes a few fixes from the list, but in particular the SRF fixes from Ranjith so that DVFS can be done again.

Basic testing on SDP and EVM only.

This page includes the stuff I normally put in the announcment of a new PM branch, but also tries to describe how to use the various features of the PM branch (which has been sorely missing for a while.)

Comments/feedback welcome, and feel free to update/edit as well.

I think this page had been long-awaited. Thanks a lot for putting it together.

One question about it:

What about the cpufreq interface for doing DVFS? Is it preferred way to change OPPs or is it using /sys/power/vddx_opp? I think cpufreq utils are more standard, easier to use and to understand.

CPUfreq is much preferred. The /sys/power/vdd* are just for manual testing and more fore PM developers than PM users.

Hey, sounds like a perfect opportunity for you to update the wiki. ;)
