  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).

  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.

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

 900                 needs to be applied prior to masking out unused bits. Some
 901                 devices put their data in the middle of the transferred elements
 902                 with additional information on both sides.  Note that some
 903                 devices will have additional information in the unused bits
 904                 so to get a clean value, the bits value must be used to mask
 905                 the buffer output value appropriately.  The storagebits value
 906                 also specifies the data alignment.  So s48/64>>2 will be a
 907                 signed 48 bit integer stored in a 64 bit location aligned to
 908                 a 64 bit boundary. To obtain the clean value, shift right 2
 909                 and apply a mask to zero the top 16 bits of the result.
 910                 For other storage combinations this attribute will be extended
 911                 appropriately.
