+Description:
+                The /sys/power/pm_print_times file allows user space to
+                control whether the time taken by devices to suspend and
+                resume is printed.  These prints are useful for hunting down
+                devices that take too long to suspend or resume.
+
+                Writing a "1" enables this printing while writing a "0"
+                disables it.  The default value is "0".  Reading from this file
+                will display the current value.

 Device low-power states aren't standard.  One device might only handle
