Power Management Functions

The power management functions are:

ddi_removing_power(): Check if device loses power with DDI_SUSPEND
pci_report_pmcap(): Report the power management capability of a PCI device
pm_busy_component(): Mark a component as busy
pm_idle_component(): Mark a component as idle
pm_raise_power(): Raise the power level of a component
pm_lower_power(): Lower the power level of a component
pm_power_has_changed(): Notify the power management framework of an autonomous power level change
pm_trans_check(): Device power cycle advisory check

Table B-10 Deprecated Power Management Functions

Function Name	Description
`ddi_dev_is_needed()`	Inform the system that a device's component is required
`pm_create_components()`	Create power-manageable components
`pm_destroy_components()`	Destroy power-manageable components
`pm_get_normal_power()`	Get the normal power level of a device component
`pm_set_normal_power()`	Set the normal power level of a device component
