Hello,
The following patchset is an attempt to collect the various PM  
patches
that have been flowing around, and organize them into one branch to  
be
used for further collaboration on PM development, in particular
OFF-mode support.

This series has been rebased onto today's OMAP git, and pushed as  
branch pm-0.

I will now start collecting more recent versions of these patches  
and newer patches sent to the list for the next version of the branch.

What are your plans for including the omap3 cpufreq patchset?

regards,

It is currently a collection of proposed patches[1] from TI and
various other patches from Nokia and others to get retention,
OFF-mode, CPUidle etc. working in the linux-omap tree.
This series is nowhere near ready for merging into linux-omap, but
will be useful for discussion and collaboration on getting the  
various
PM features working at the head of the linux-omap tree, and a place
where cleanup and rework efforts can be focused.  If there are no  
major objections, I will create a branch in linux-omap
git and commit this series there.  As collaboration continues, I will
continue to collect and update patches, fix problems and rebase onto
the HEAD of linux-omap.  The goal of this branch is only to  
facilitate the rework and cleanup
of the PM code so it can be merged into linux-omap.  Then, the branch
will disappear and work can be focused again on the HEAD of
linux-omap.
It has currently been tested with a minimal config on 3430SDP, and
OFF-mode is hit in suspend.  In order to hit suspend:
 echo 1 > /sys/power/voltage_off_while_idle                      
echo 1 > /sys/power/gpio_clocks_off_while_idle                 echo  
1 > /sys/power/uart_clocks_off_while_idle   echo mem > /sys/power/ 
state

[1] This series is roughly based on the following:
Jouni Hogander, Tero Kristo
[PATCH 0/4] Refreshed PM workaround patches 2 -- 15 Aug
Rajendra Nayak:
[PATCH 00/11] OMAP3 CPUidle patches - ver 2 -- 18 July
As well as several patches/hacks/cleanups that have not yet been
posted to the list.
Also, there have been newer versions of the CPUidle patches that have
been reviewed on the list, but do not apply for various reasons.  As
soon as they are rebased and updated versions of those are available,
I will integrate them.
