Not currently... It should be in the future.
But hibernation on memory works with a 'power domain' board based
therefore it's easy to implement in the customer board.

For some IP it's required.

What do you have in mind?
Currently we release a kernel tool to leave the customer able to design
their our power profile.
This means the system is moved from a profile to an other....
A real runtime power management requires a support linux currently
doesn't have.
