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.
