I have designed custom power management framework for free scale Imx51 platform.  To support Suspend to RAM power state,
 I'm looking QNX BSP support to manage independently power-managed components; such as CPU, memory and individual 
peripheral devices.

To be specific, I want to put CPU into low power mode (STOP mode as per Imx51 reference manual) and RAM into self-
refresh mode. I identified “power callout” in startup code can be used for this purpose.
But not seen power() callout implementation on BSP(6.5.0 SP1).  Is power() callout part of BSP? 
Can anyone point me towards how to get BSP with power() callout.

Is any support/service available for device power management (suspend/resume) on BSP individual peripheral device 
drivers?
