Hello Team,
I’m trying to work on “suspend to idle” and “deep” sleep mode for the i.mx8m-Plus.
My requirements are: put the processor in a low-power or sleep mode and wake it up with an external signal. Wanted a better understanding of what peripherals are in which state at that time and what services are available during this hibernation mode.
Tried to go through the documentation but not much information is revealed, any help would be appreciated.
You can refer the kernel document:

and ATF source code:
