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.

485 Event generated when channel passes a threshold in the specified
486 (_rising|_falling) direction. If the direction is not specified,
487 then either the device will report an event which ever direction
488 a single threshold value is passed in (e.g.
489 <type>[Y][_name]_<raw|input>_thresh_value) or
490 <type>[Y][_name]_<raw|input>_thresh_rising_value and
491 <type>[Y][_name]_<raw|input>_thresh_falling_value may take
492 different values, but the device can only enable both thresholds
494 Note the driver will assume the last p events requested are
495 to be enabled where p is how many it supports (which may vary
496 depending on the exact set requested. So if you want to be
497 sure you have set what you think you have, check the contents of
498 these attributes after everything is configured. Drivers may
499 have to buffer any parameters so that they are consistent when
500 a given event type is enabled at a future point (and not those for
501 whatever event was previously enabled).

660 Specifies the hysteresis of threshold that the device is comparing

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

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