new PM branch available

[Kevin Hilman <khilman@deeprootsystems.com>]

Hello,

The latest PM branch is now available[1].

I've done basic testing of retention and off-mode (suspend and dynamic
idle) on Beagle and custom HW.  My SDP has something still keeping
CORE active that others have not seen, but I have yet to debug.  Any
other reports from SDP testing would be appreciated.

Notable changes/updates
- rebased on latest clock updates and fixes from Paul
- clockfw pre- and post- notifiers
- DVFS for VDD2

Full git shortlog below[2]

Enjoy,

Kevin

[1] See branch 'pm' in my git repo:
git://git.kernel.org/pub/scm/linux/kernel/git/khilman/linux-omap-pm.git
which is also mirrored as the branch 'pm' of the normal linux-omap
repo (but will not sync until 03:30 GMT)
