| 23 | Set the trigger for this LED. A trigger is a kernel based source |
| 24 | of led events. |
| 25 | You can change triggers in a similar manner to the way an IO |
| 26 | scheduler is chosen. Trigger specific parameters can appear in |
| 27 | /sys/class/leds/<led> once a given trigger is selected. |
