83  * dev_pm_domain_attach - Attach a device to its PM domain.
87  * The @dev may only be attached to a single PM domain. By iterating through
88  * the available alternatives we try to find a valid PM domain for the device.
94  * power management through PM domains.
99  * Returns 0 on successfully attached PM domain, or when it is found that the
100  * device doesn't need a PM domain, else a negative error code.
118  * dev_pm_domain_attach_by_id - Associate a device with one of its PM domains.
119  * @dev: The device used to lookup the PM domain.
120  * @index: The index of the PM domain.
122  * As @dev may only be attached to a single PM domain, the backend PM domain
129  * in case its device requires power management through multiple PM domains. The
133  * the power to the PM domains independently from each other.
138  * Returns the virtual created device when successfully attached to its PM
139  * domain, NULL in case @dev don't need a PM domain, else an ERR_PTR().
154  * dev_pm_domain_attach_by_name - Associate a device with one of its PM domains.
155  * @dev: The device used to lookup the PM domain.
156  * @name: The name of the PM domain.
171  * dev_pm_domain_detach - Detach a device from its PM domain.
177  * detaches @dev from its PM domain.  Typically it should be invoked during the
191  * dev_pm_domain_start - Start the device through its PM domain.
195  * when it needs to start its device from the PM domain's perspective. Note
196  * that, it's assumed that the PM domain is already powered on when this
211  * dev_pm_domain_set - Set PM domain of a device.
212  * @dev: Device whose PM domain is to be set.
213  * @pd: PM domain to be set, or NULL.
215  * Sets the PM domain the device belongs to. The PM domain of a device needs
226 	     "PM domains can only be changed for unbound devices\n");  in dev_pm_domain_set()
238  * requested for a device that is attached to a PM domain. Note that, the
239  * support for performance scaling for PM domains is optional.
