+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.
