2. Add a procfs option to the PM driver that exposes /procfs/power/state which
can be modified from the user space as well.
Currently the procfs is read-only, but there is no reason that I can
think of that we could no extended to support writing.

Calling those functions from applications would be a violation of
OS/application isolation, as these are OS level calls.
The general idea is that a driver only knows what to do on each sleep level and
the IDLE loop uses those functions to drive the change of states of PM system.

The interaction between hardware on/off and sleep states usually occurs on IDLE
loop. I'm not sure if you are aware of this option but you can have a board
specific idle loop implementation. This is wha

Hi Matias,
I indeed saw that there are several governors.
I implemented PM switches in the application code (you could see this as a
governor), there is for example a sleep state of the application, there the
PM_SLEEP state is used to set the MCU in a very low power state.
Another one is the PM
