pm_debug/voltage_off_while_idle has gone?

[Mike Rapoport]

There used to be 'voltage_off_while_idle' attribute in the PM-enabled kernels 
that allowed to put PMIC into OFF mode.
In the current tip of the linux-omap-pm tree this attribute seem to be gone
Is there possibility to make PMIC enter the OFF mode when suspending to RAM?

Hi Mike,

We are currently in the middle of a major rewrite of the SmartReflex and
voltage layers of the PM branch.

The previous voltage-related work (like voltage_off_while_idle) are
still available in the pm-vc branch of my tree, but are not currently
merged with the new voltage work due to conflicts.

For this particular feature, I suspect you could just apply the first
patch in my pm-vc branch to add back this feature.

Let me know if that works,

Kevin

I've cherry-picked two commits from your pm-vc and it failed to compile :)
After fixing it, I did several small tests, but is seems that PMIC does not 
execute the power scripts... I'll continue to work on it.
