- * NEVER_SKIP: Do not skip all system suspend/resume callbacks for the device.
- * SMART_PREPARE: Check the return value of the driver's ->prepare callback.
- * SMART_SUSPEND: No need to resume the device from runtime suspend.
- * LEAVE_SUSPENDED: Avoid resuming the device during system resume if possible.

+ * SMART_SUSPEND: Avoid resuming the device from runtime suspend.
+ * MAY_SKIP_RESUME: Allow driver "noirq" and "early" callbacks to be skipped.

- * Setting SMART_PREPARE instructs bus types and PM domains which may want
- * system suspend/resume callbacks to be skipped for the device to return 0 from
- * their ->prepare callbacks if the driver's ->prepare callback returns 0 (in
- * other words, the system suspend/resume callbacks can only be skipped for the
- * device if its driver doesn't object against that). This flag has no effect
- * if NEVER_SKIP is set.
- *
- * Setting SMART_SUSPEND instructs bus types and PM domains which may want to
- * runtime resume the device upfront during system suspend that doing so is not
- * necessary from the driver's perspective. It also may cause them to skip
- * invocations of the ->suspend_late and ->suspend_noirq callbacks provided by
- * the driver if they decide to leave the device in runtime suspend.
- *
- * Setting LEAVE_SUSPENDED informs the PM core and middle-layer code that the
- * driver prefers the device to be left in suspend after system resume.
