subsystem-level callbacks. Specifically, if a device's pm_domain pointer is
not NULL, the ->suspend() callback from the object pointed to by it will be
executed instead of its subsystem's (e.g. bus type's) ->suspend() callback and
-anlogously for all of the remaining callbacks. In other words, power management
-domain callbacks, if defined for the given device, always take precedence over
-the callbacks provided by the device's subsystem (e.g. bus type).

The support for device power management domains is only relevant to platforms
needing to use the same device driver power management callbacks in many
Device Low Power (suspend) States
---------------------------------
Device low-power states aren't standard. One device might only handle
-"on" and "off, while another might support a dozen different versions of
+"on" and "off", while another might support a dozen different versions of
"on" (how many engines are active?), plus a state that gets back to "on"
faster than from a full "off".
