Shubhrajyoti, thanks for the updates.

Wolfgang, with these updates and testing a bit better described, I'm OK with you merging it. Merging it now will give it plenty of time to bake in linux-next and get more test exposure.

Thanks,

Kevin

Tested on omap4sdp and omap3sdp.
- Did functional tests read write on both the platforms.
- Off mode and retention on OMAP3
- On OMAP4 just did echo mem > /sys/power/state and wakeup. Did see.

[ 1360.595855] Successfully put all powerdomains to target state

However didnt see the ret count for other than mpu_pwrdm increase. I think power support for omap4 is minimal.
