NAME

       device_pm_set_parent - Specify power dependency.

SYNOPSIS

       void device_pm_set_parent  (struct device * dev,
                                    struct device * parent);

ARGUMENTS

       dev    Device who needs power.

       parent Device that supplies power.

DESCRIPTION

       This  function  is  used  to  manually  describe   a   power-dependency
       relationship.  It  may  be  used  to specify a transversal relationship
       (where the power supplier is not the physical (or electrical)  ancestor
       of  a specific device. The effect of this is that the supplier will not
       be powered down before the power dependent.
