| Description: |
| An event driven driver of data capture to an in kernel buffer. |
| May be provided by a device driver that also has an IIO device |
| based on hardware generated events (e.g. data ready) or |
| provided by a separate driver for other hardware (e.g. |
| periodic timer, GPIO or high resolution timer). |
| Contains trigger type specific elements. These do not |
| generalize well and hence are not documented in this file. |
| X is the IIO index of the trigger. |

| KernelVersion: 2.6.35 |
| Contact: linux-iio@vger.kernel.org |
| Description: |
| Some devices have internal clocks. This parameter sets the |
| resulting sampling frequency. In many devices this |
| parameter has an effect on input filters etc rather than |
| simply controlling when the input is sampled. As this |
| effects datardy triggers, hardware buffers and the sysfs |
| direct access interfaces, it may be found in any of the |
| relevant directories. If it effects all of the above |
| then it is to be found in the base device directory as here. |

| Description: |
| Event generated when channel passes a threshold in the specified |
| (_rising|_falling) direction. If the direction is not specified, |

| <type>[Z][_name]_<raw|input>_thresh_rising_value and |

| different values, but the device can only enable both thresholds |
| or neither. |
| Note the driver will assume the last p events requested are |
| to be enabled where p is however many it supports (which may |
| vary depending on the exact set requested. So if you want to be |
| sure you have set what you think you have, check the contents of |
| these attributes after everything is configured. Drivers may |
| have to buffer any parameters so that they are consistent when |
| a given event type is enabled a future point (and not those for |
| whatever event was previously enabled). |

| Description: |
| Description of the scan element data storage within the buffer |
| and hence the form in which it is read from user-space. |
| Form is [s|u]bits/storagebits[>>shift]. s or u specifies if |
| signed (2's complement) or unsigned. bits is the number of bits |
| of data and storagebits is the space (after padding) that it |
| occupies in the buffer. shift if specified, is the shift that |
| needs to be applied prior to masking out unused bits. Some |
| devices put their data in the middle of the transferred elements |
| with additional information on both sides. Note that some |
| devices will have additional information in the unused bits |
| so to get a clean value, the bits value must be used to mask |
| the buffer output value appropriately. The storagebits value |
| also specifies the data alignment. So s48/64>>2 will be a |
| signed 48 bit integer stored in a 64 bit location aligned to |
| a a64 bit boundary. To obtain the clean value, shift right 2 |
| and apply a mask to zero the top 16 bits of the result. |
| For other storage combinations this attribute will be extended |
| appropriately. |

| Description: |
| A single positive integer specifying the position of this |
| scan element in the buffer. Note these are not dependent on |
| what is enabled and may not be contiguous. Thus for user-space |
| to establish the full layout these must be used in conjunction |
| with all _en attributes to establish which channels are present, |
| and the relevant _type attributes to establish the data storage |
| format. |
