+Description:
+ This attribute is provided by the iio-trig-sysfs stand-alone
+ driver and it is used to activate the creation of a new trigger.
+ In order to achieve this, one should write a positive integer
+ into the associated file, which will serve as the id of the
+ trigger. If the trigger with the specified id is already present
+ in the system, an invalid argument message will be returned.
