4Description:
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.

16Description:
17 The name attribute holds a description string for the current
18 trigger. In order to associate the trigger with an IIO device
19 one should write this name string to
20 /sys/bus/iio/devices/iio:deviceY/trigger/current_trigger.

25Description:
26 This attribute is provided by the iio-trig-sysfs stand-alone
27 driver and it is used to activate the creation of a new trigger.
28 In order to achieve this, one should write a positive integer
29 into the associated file, which will serve as the id of the
30 trigger. If the trigger with the specified id is already present
31 in the system, an invalid argument message will be returned.

36Description:
37 This attribute is used to unregister and delete a previously
38 created trigger from the list of available triggers. In order to
39 achieve this, one should write a positive integer into the
40 associated file, representing the id of the trigger that needs
41 to be removed. If the trigger can't be found, an invalid
42 argument message will be returned to the user.
