    NAME
         pm_get_normal_power, pm_set_normal_power - Get or set a dev-
         ice component's normal power level
    
    SYNOPSIS
         #include <sys/ddi.h>
         #include <sys/sunddi.h>
    
         int pm_get_normal_power(dev_info_t *dip, int component);
    
         void pm_set_normal_power(dev_info_t *dip, int component, int
         level);
    
    INTERFACE LEVEL
         Solaris DDI specific (Solaris DDI)
    
    PARAMETERS
      pm_get_normal_power
         dip   Pointer to the device's  dev_info structure
    
         component
               Number of component from which  to  get  normal  power
               level
    
      pm_set_normal_power
         dip   Pointer to the device's   dev_info structure
    
         component
               Number of component for  which  to  set  normal  power
               level
    
         level Component's new normal power level
    
    DESCRIPTION
          The pm_get_normal_power() and  pm_set_normal_power()  func-
         tions  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.
    
    RETURN VALUES
         The pm_get_normal_power() function returns:
    
              level The normal power level of the specified component
                    (a positive integer).
    
              DDI_FAILURE
                    Invalid component number  component or the device
                    has no components.
    
    
    CONTEXT
         These functions can be called from user or kernel context.
