This option enables the board to implement extra power management
policies whenever the kernel becomes idle. The kernel informs the
power management subsystem of the number of ticks until the next kernel
timer is due to expire.

power: Rework OS <-> Application interface This commit simplifies OS <-> Application interface controlling power management. In the previous approach application-based PM required overriding sys_suspend() and sys_resume() functions. As these functions actually implemented power state change, in such case application basically had to provide own implementation of all PM-related stuff, which was not portable and hard to maintain. This commit changes this scheme: The sys_suspend() and sys_resume() are now system functions while the application could either use built-in power management policies or provide its own. All details of power mode switching are now handled by the OS. Also, this commit cleans up the Kconfig options related to system-level power management grouping them under common CONFIG_SYS_PM_ prefix. Signed-off-by: Piotr Zięcik <piotr.ziecik@nordicsemi.no>

logging: Refactor LOG_MODULE_REGISTER and LOG_MODULE_DECLARE macros Changed LOG_MODULE_REGISTER and LOG_MODULE_DECLARE macros to take log level as optional parameter. LOG_MODULE_DECLARE can now also be used in static inline functions in headers. Added LOG_LEVEL_SET macro which is used when instance logging API is used to indicate maximal log level compiled into the file.

This option blocks selection of PM. It can be selected in SOC
targets where system power management is not supported, for example
on support core of a multi-core device where SoC power management is
the responsibility of a different core.

bool "Device power management"
help
This option enables the device power management interface. The
interface consists of hook functions implemented by device drivers
that get called by the power manager application when the system
is going to suspend state or resuming from suspend state. This allows
device drivers to do any necessary power management operations
like turning off device clocks and peripherals. The device drivers
may also save and restore states in these hook functions.
