- 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.

- enabled, devices can be suspended or resumed based on the device
- usage even while the CPU or system is running.
