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.

on support core of a multi-core device where SoC power management is

the responsibility of a different core.

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.
