+Description:
+               This file is provided by the iio-trig-sysfs stand-alone trigger
+               driver. Writing this file with any value triggers an event
+               driven driver, associated with this trigger, to capture data
+               into an in kernel buffer. This approach can be valuable during
+               automated testing or in situations, where other trigger methods
+               are not applicable. For example no RTC or spare GPIOs.
+               X is the IIO index of the trigger.
