12Description:

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 data ready 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.

434Description:
435		Event generated when channel passes a threshold in the specified
436		(_rising|_falling) direction. If the direction is not specified,
437		then either the device will report an event which ever direction
438		a single threshold value is passed in (e.g.
439		<type>[Y][_name]_<raw|input>_thresh_value) or
440		<type>[Y][_name]_<raw|input>_thresh_rising_value and
441		<type>[Y][_name]_<raw|input>_thresh_falling_value may take
442		different values, but the device can only enable both thresholds
443		or neither.
444		Note the driver will assume the last p events requested are
445		to be enabled where p is how many it supports (which may vary
446		depending on the exact set requested. So if you want to be
447		sure you have set what you think you have, check the contents of
448		these attributes after everything is configured. Drivers may
449		have to buffer any parameters so that they are consistent when
450		a given event type is enabled at a future point (and not those for
451		whatever event was previously enabled).

581Description:
582		Specifies the hysteresis of threshold that the device is comparing

585		If separate attributes exist for the two directions, but
586		direction is not specified for this attribute, then a single
587		hysteresis value applies to both directions.
588		For falling events the hysteresis is added to the _value attribute for
589		this event to get the upper threshold for when the event goes back to
590		normal, for rising events the hysteresis is subtracted from the _value
591		attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
592		and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
593		will get activated once in_voltage0_raw goes above 1200 and will become
594		deactived again once the value falls below 1150.

791Description:
792		Description of the scan element data storage within the buffer
793		and hence the form in which it is read from user-space.
794		Form is [be|le]:[s|u]bits/storagebits[>>shift].
795		be or le specifies big or little endian. s or u specifies if
796		signed (2's complement) or unsigned. bits is the number of bits
797		of data and storagebits is the space (after padding) that it
798		occupies in the buffer. shift if specified, is the shift that
799		needs to be applied prior to masking out unused bits. Some
800		devices put their data in the middle of the transferred elements
801		with additional information on both sides.  Note that some
802		devices will have additional information in the unused bits
803		so to get a clean value, the bits value must be used to mask
804		the buffer output value appropriately.  The storagebits value
805		also specifies the data alignment.  So s48/64>>2 will be a
806		signed 48 bit integer stored in a 64 bit location aligned to
807		a 64 bit boundary. To obtain the clean value, shift right 2
808		and apply a mask to zero the top 16 bits of the result.
809		For other storage combinations this attribute will be extended
810		appropriately.
