Sorry to be late to the party (again), but still catching up after some
time off.

Unfortunately, this series causes PM regressions on several OMAP
platforms.  I hope we can hold off on this until those issues are
addressed.

I tracked the regression down to [PATCHv8 21/22] (see reply there.)

Since this series is already merged, I suggest that the problem patch be
reverted, at least for v3.7 and until the problem is better understood
and tested.

With that patch reverted, all my PM tests are passing.  Feel free to
add:

OK, the i2c series is off the hook.

Felipe and I spent a little time tracking this down.  Felipe suggested
that there might be a driver with periodic i2c activity keeping I2C
awake, and thus preventing CORE retention.  He was right.

FYI, the original idea came from Shubhro. We agreed that would be the
only way i2c would be prevented from idling.

Great, thanks Shubhro!

Also, FYI, I just submitted a patch to the TWL RTC driver which was the
source of all the I2C activity since it's on the I2C-connected PMIC.

Thanks for the help and suggestions,

Kevin
