Driver Interface -- OBSOLETE, DO NOT USE!

----------------*************************



Note: pm_register(), pm_access(), pm_dev_idle() and friends are

obsolete. Please do not use them. Instead you should properly hook

your driver into the driver model, and use its suspend()/resume()

callbacks to do this kind of stuff.



If you are writing a new driver or maintaining an old driver, it

should include power management support.  Without power management

support, a single driver may prevent a system with power management
