^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  6) 		driver. Writing this file with any value triggers an event
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  7) 		driven driver, associated with this trigger, to capture data
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  8) 		into an in kernel buffer. This approach can be valuable during
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300  9) 		automated testing or in situations, where other trigger methods
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 10) 		are not applicable. For example no RTC or spare GPIOs.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 11) 		X is the IIO index of the trigger.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 18) 		trigger. In order to associate the trigger with an IIO device
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 19) 		one should write this name string to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 20) 		/sys/bus/iio/devices/iio:deviceY/trigger/current_trigger.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 27) 		driver and it is used to activate the creation of a new trigger.
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 28) 		In order to achieve this, one should write a positive integer
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 29) 		into the associated file, which will serve as the id of the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 30) 		trigger. If the trigger with the specified id is already present
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 31) 		in the system, an invalid argument message will be returned.

^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 37) 		This attribute is used to unregister and delete a previously
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 38) 		created trigger from the list of available triggers. In order to
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 39) 		achieve this, one should write a positive integer into the
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 40) 		associated file, representing the id of the trigger that needs
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 41) 		to be removed. If the trigger can't be found, an invalid
^8f3ce5b39 (kx 2023-10-28 12:00:06 +0300 42) 		argument message will be returned to the user.
