CONFIG_DEVICE_POWER_MANAGEMENT

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.
