+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.

+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.
