  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).

  19                 generalize well and hence are not documented in this file.

  40 Description:
  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.

 645 Description:
 646                 Specifies the hysteresis of threshold that the device is comparing
 647                 against for the events enabled by
 648                 <type>Y[_name]_thresh[_(rising|falling)]_hysteresis.
 649                 If separate attributes exist for the two directions, but
 650                 direction is not specified for this attribute, then a single
 651                 hysteresis value applies to both directions.
 652                 For falling events the hysteresis is added to the _value attribute for
 653                 this event to get the upper threshold for when the event goes back to
 654                 normal, for rising events the hysteresis is subtracted from the _value
 655                 attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
 656                 and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
 657                 will get activated once in_voltage0_raw goes above 1200 and will become
 658                 deactived again once the value falls below 1150.

 888                 Form is [be|le]:[s|u]bits/storagebits[>>shift].
 889                 be or le specifies big or little endian. s or u specifies if
 890                 signed (2's complement) or unsigned. bits is the number of bits
 891                 of data and storagebits is the space (after padding) that it
 892                 occupies in the buffer. shift if specified, is the shift that
 893                 needs to be applied prior to masking out unused bits. Some
 894                 devices put their data in the middle of the transferred elements

 896                 devices will have additional information in the unused bits
 897                 so to get a clean value, the bits value must be used to mask
 898                 the buffer output value appropriately.  The storagebits value
 899                 also specifies the data alignment.  So s48/64>>2 will be a
 900                 signed 48 bit integer stored in a 64 bit location aligned to
 901                 a 64 bit boundary. To obtain the clean value, shift right 2
