| 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. | |

| 16 | Description: | |
| 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. | |

| 25 | Description: | |
| 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. | |

| 35 | Contact: linux-iio@vger.kernel.org | |
| 36 | Description: | |
| 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. |
