 | KernelVersion:	2.6.38 | 
 | Contact:	linux-iio@vger.kernel.org | 
 | Description: | 
 | 		This file is provided by the iio-trig-sysfs stand-alone trigger | 
 | 		driver. Writing this file with any value triggers an event | 
 | 		driven driver, associated with this trigger, to capture data | 
 | 		into an in kernel buffer. This approach can be valuable during | 
 | 		automated testing or in situations, where other trigger methods | 
 | 		are not applicable. For example no RTC or spare GPIOs. | 
 | 		X is the IIO index of the trigger. |

 | What:		/sys/bus/iio/devices/triggerX/name | 
 | KernelVersion:	2.6.39 | 
 | Contact:	linux-iio@vger.kernel.org | 
 | Description: | 
 | 		The name attribute holds a description string for the current | 
 | 		trigger. In order to associate the trigger with an IIO device | 
 | 		one should write this name string to | 
 | 		/sys/bus/iio/devices/iio:deviceY/trigger/current_trigger. |

 | KernelVersion:	2.6.39 | 
 | Contact:	linux-iio@vger.kernel.org | 
 | 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. | 
 |  | 
 | What:		/sys/bus/iio/devices/iio_sysfs_trigger/remove_trigger | 
 | KernelVersion:	2.6.39 | 
 | Contact:	linux-iio@vger.kernel.org | 
 | Description: | 
 | 		This attribute is used to unregister and delete a previously | 
 | 		created trigger from the list of available triggers. In order to | 
 | 		achieve this, one should write a positive integer into the | 
 | 		associated file, representing the id of the trigger that needs | 
 | 		to be removed. If the trigger can't be found, an invalid | 
 | 		argument message will be returned to the user. |
