device_pm_set_parent - Specify power dependency.
void device_pm_set_parent (struct device * dev,
struct device * parent);
dev Device who needs power.
parent Device that supplies power.
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.
