Hi, All, 

   I am running the linux-pm-kernel v2.35.rc3 on Overo Earth. I have managed to
suspend the system using "echo mem > /sys/power/state" with "enable_off_mode" 
and "sleep_while_idle" enabled. Currently, I am able to achieve 200mW in 
suspend 
mode. However, I am seen in other posts, such as this  one  
(http://old.nabble.com/
Overo-boot-time--power-management-ts28402656.html#a28463135), that 
people are able to achieve a much lower power signature.
  
   I am particularly interested to know what mode has the SDRAM on Overo  been 
set to 
during suspend mode? Is it auto-refresh or self-refresh? And whether the 
TPS/TWL 
power management chip is set to low power mode during suspend mode by the pm
kernel, if not, how to set it?

Thanks,
Han
