Method for Powering of device

Hi,

How do we power down a device.

I detect the power off button pressed, which will be intimated to the application.

I am confused on to what is the correct way of powering down the system.

As of now I thought of implementing as follows.

The application sends an ioctl to a driver stub, which will call pxa_pm_enter () function.

I see the pxa_pm_enter() is a static function. Is it the right way to make it global and call it.

Can any one shed some light on the subject.

 

Regards,

Sridhar.
