Description:
The /sys/devices/.../wakeup_prevent_sleep_time_ms attribute
contains the total time the device has been preventing
- opportunistic transitions to sleep states from occuring.
+ opportunistic transitions to sleep states from occurring.
This attribute is read-only. If the device is not enabled to
wake up the system from sleep states, this attribute is not
present.
This attribute has no effect on system-wide suspend/resume and
hibernation.

+What: /sys/devices/.../power/pm_qos_no_power_off
+Date: September 2012
+Contact: Rafael J. Wysocki <rjw@sisk.pl>
+Description:
+ The /sys/devices/.../power/pm_qos_no_power_off attribute
+ is used for manipulating the PM QoS "no power off" flag. If
+ set, this flag indicates to the kernel that power should not
+ be removed entirely from the device.
+
+ Not all drivers support this attribute. If it isn't supported,
+ it is not present.
+
+ This attribute has no effect on system-wide suspend/resume and
+ hibernation.

+What: /sys/devices/.../power/pm_qos_remote_wakeup
+Date: September 2012
+Contact: Rafael J. Wysocki <rjw@sisk.pl>
+Description:
+ The /sys/devices/.../power/pm_qos_remote_wakeup attribute
+ is used for manipulating the PM QoS "remote wakeup required"
+ flag. If set, this flag indicates to the kernel that the
+ device is a source of user events that have to be signaled from
+ its low-power states.
+
+ Not all drivers support this attribute. If it isn't supported,
+ it is not present.
+
+ This attribute has no effect on system-wide suspend/resume and
+ hibernation.
