Just gave this branch a quick try, it seems to work with off-idle
for me when merged with current linux-omap master branch. The following
merge resolution is needed because of the recent pre es3.1 fix though.

I've pushed out this merged with all the other pending patches into
omap-for-v3.18/tmp-merge-2014-09-18.

Nishant, care to give it a try and check your recent PM related
changes work with it?

Regards,

Tony
