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