   This means that support for the SO_TIMESTAMPING socket option is also removed
   as it was used by the removed config option.
 
+* The device power management (PM) APIs and data structures have been renamed
+  from ``device_pm_*`` to ``pm_device_*`` since they are not device APIs but PM
+  subsystem APIs. The same applies to enumerations and definitions, they now
+  follow the ``PM_DEVICE_*`` convention. Some other API calls such as
+  ``device_set_power_state`` and ``device_get_power_state`` have been renamed to
+  ``pm_device_state_set`` and ``pm_device_state_get`` in order to align with
+  the naming of other device PM APIs.
