11Contact: linux-iio@vger.kernel.org
12Description:
13 An event driven driver of data capture to an in kernel buffer.
14 May be provided by a device driver that also has an IIO device
15 based on hardware generated events (e.g. data ready) or
16 provided by a separate driver for other hardware (e.g.
17 periodic timer, GPIO or high resolution timer).
18 Contains trigger type specific elements. These do not
19 generalize well and hence are not documented in this file.
20 X is the IIO index of the trigger.

39Contact: linux-iio@vger.kernel.org
40Description:
41 Some devices have internal clocks. This parameter sets the
42 resulting sampling frequency. In many devices this
43 parameter has an effect on input filters etc rather than
44 simply controlling when the input is sampled. As this
45 effects datardy triggers, hardware buffers and the sysfs
46 direct access interfaces, it may be found in any of the
47 relevant directories. If it effects all of the above
48 then it is to be found in the base device directory.

203Description:
204 If known for a device, offset to be added to <type>[Y]_raw prior
205 to scaling by <type>[Y]_scale in order to obtain value in the
206 <type> units as specified in <type>[y]_raw documentation.
207 Not present if the offset is always 0 or unknown. If Y or
208 axis <x|y|z> is not present, then the offset applies to all
209 in channels of <type>.
210 May be writable if a variable offset can be applied on the
211 device. Note that this is different to calibbias which
212 is for devices (or drivers) that apply offsets to compensate
213 for variation between different instances of the part, typically
214 adjusted by using some hardware supported calibration procedure.
215 Calibbias is applied internally, offset is applied in userspace
216 to the _raw output.

375Description:
376 Event generated when channel passes a threshold in the specified
377 (_rising|_falling) direction. If the direction is not specified,
378 then either the device will report an event which ever direction
379 a single threshold value is passed in (e.g.
380 <type>[Y][_name]_<raw|input>_thresh_value) or
381 <type>[Y][_name]_<raw|input>_thresh_rising_value and
382 <type>[Y][_name]_<raw|input>_thresh_falling_value may take
383 different values, but the device can only enable both thresholds
384 or neither.
385 Note the driver will assume the last p events requested are
386 to be enabled where p is however many it supports (which may
387 vary depending on the exact set requested. So if you want to be
388 sure you have set what you think you have, check the contents of
389 these attributes after everything is configured. Drivers may
390 have to buffer any parameters so that they are consistent when
391 a given event type is enabled a future point (and not those for
392 whatever event was previously enabled).

420Description:
421 Event generated when channel passes a threshold on the rate of
422 change (1st differential) in the specified (_rising|_falling)
423 direction. If the direction is not specified, then either the
424 device will report an event which ever direction a single
425 threshold value is passed in (e.g.
426 <type>[Y][_name]_<raw|input>_roc_value) or
427 <type>[Y][_name]_<raw|input>_roc_rising_value and
428 <type>[Y][_name]_<raw|input>_roc_falling_value may take
429 different values, but the device can only enable both rate of
430 change thresholds or neither.
431 Note the driver will assume the last p events requested are
432 to be enabled where p is however many it supports (which may
433 vary depending on the exact set requested. So if you want to be
434 sure you have set what you think you have, check the contents of
435 these attributes after everything is configured. Drivers may
436 have to buffer any parameters so that they are consistent when
437 a given event type is enabled a future point (and not those for
438 whatever event was previously enabled).

672Description:
673 Description of the scan element data storage within the buffer
674 and hence the form in which it is read from user-space.
675 Form is [be|le]:[s|u]bits/storagebits[>>shift].
676 be or le specifies big or little endian. s or u specifies if
677 signed (2's complement) or unsigned. bits is the number of bits
678 of data and storagebits is the space (after padding) that it
679 occupies in the buffer. shift if specified, is the shift that
680 needs to be applied prior to masking out unused bits. Some
681 devices put their data in the middle of the transferred elements
682 with additional information on both sides. Note that some
683 devices will have additional information in the unused bits
684 so to get a clean value, the bits value must be used to mask
685 the buffer output value appropriately. The storagebits value
686 also specifies the data alignment. So s48/64>>2 will be a
687 signed 48 bit integer stored in a 64 bit location aligned to
688 a a64 bit boundary. To obtain the clean value, shift right 2
689 and apply a mask to zero the top 16 bits of the result.
690 For other storage combinations this attribute will be extended
691 appropriately.
