| 		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.

| 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 data ready 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.

 | |
| 		Specifies the hysteresis of threshold that the device is comparing

| 		<type>Y[_name]_thresh[_(rising|falling)]_hysteresis.
 | |
| 		If separate attributes exist for the two directions, but
 | |
| 		direction is not specified for this attribute, then a single
 | |
| 		hysteresis value applies to both directions.
 | |
| 		For falling events the hysteresis is added to the _value attribute for
 | |
| 		this event to get the upper threshold for when the event goes back to
 | |
| 		normal, for rising events the hysteresis is subtracted from the _value
 | |
| 		attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
 | |
| 		and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
 | |
| 		will get activated once in_voltage0_raw goes above 1200 and will become
 | |
| 		deactived again once the value falls below 1150.

| Description:
 | |
| 		Specifies the value of rate of change threshold that the
 | |
| 		device is comparing against for the events enabled by
 | |
| 		<type>[Y][_name]_roc[_rising|falling]_en.
 | |
| 		If separate attributes exist for the two directions,
 | |
| 		but direction is not specified for this attribute,
 | |
| 		then a single threshold value applies to both directions.
 | |
| 		The raw or input element of the name indicates whether the
 | |
| 		value is in raw device units or in processed units (as _raw
 | |
| 		and _input do on sysfs direct channel read attributes).

| 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 [be|le]:[s|u]bits/storagebits[>>shift].
 | |
| 		be or le specifies big or little endian. 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 64 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.
