The pm_get_normal_power() and pm_set_normal_power() functions are now obsolete and will be removed in a future release. It is recommended that device drivers use new automatic device Power Management interfaces.
The pm_get_normal_power() function returns the normal power level of component of the device dip.
The pm_set_normal_power() function sets the normal power level of component of the device dip to level.
When a device has been power managed and is being returned to a state to be used by the system, it will be brought to its normal power level. Except for a power level of 0, which is defined by the system to mean "powered off," the interpretation of the meaning of the power
level is entirely up to the driver.
