Well, it does depend on the hardware a bit - some hardware is hard wired
to only have one possible suspend state due to power up requirements.
But for a lot of hardware it's flexible...

This is not really relevant, it's an orthogonal thing about when we
trigger the state transition in the regulator.

It's not clear what a good solution is here, sorry.
