12Description:
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.
Jonathan Cameronf386caa2010-11-22 23:31:16 +000017 periodic timer, GPIO or high resolution timer).
Jonathan Camerone34d2c52010-05-04 14:43:05 +010018 Contains trigger type specific elements. These do not
19 generalize well and hence are not documented in this file.
Jonathan Cameronf386caa2010-11-22 23:31:16 +000020 X is the IIO index of the trigger.

717Description:
718 Specifies the hysteresis of threshold that the device is comparing
719 against for the events enabled by
720 <type>Y[_name]_thresh[_(rising|falling)]_hysteresis.
721 If separate attributes exist for the two directions, but
722 direction is not specified for this attribute, then a single
723 hysteresis value applies to both directions.
724 For falling events the hysteresis is added to the _value attribute for
725 this event to get the upper threshold for when the event goes back to
726 normal, for rising events the hysteresis is subtracted from the _value
727 attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
728 and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
729 will get activated once in_voltage0_raw goes above 1200 and will become
730 deactived again once the value falls below 1150.

Jonathan Cameron10ba8ea2010-09-21 14:41:08 +01001019 Description of the scan element data storage within the buffer
Jonathan Cameronf386caa2010-11-22 23:31:16 +00001020 and hence the form in which it is read from user-space.
Jonathan Cameron15739cd2011-09-21 11:15:51 +01001021 Form is [be|le]:[s|u]bits/storagebits[>>shift].
1022 be or le specifies big or little endian. s or u specifies if
Jonathan Cameronf386caa2010-11-22 23:31:16 +00001023 signed (2's complement) or unsigned. bits is the number of bits
1024 of data and storagebits is the space (after padding) that it
1025 occupies in the buffer. shift if specified, is the shift that
1026 needs to be applied prior to masking out unused bits. Some
1027 devices put their data in the middle of the transferred elements
1028 with additional information on both sides. Note that some
1029 devices will have additional information in the unused bits
1030 so to get a clean value, the bits value must be used to mask
1031 the buffer output value appropriately. The storagebits value
1032 also specifies the data alignment. So s48/64>>2 will be a
1033 signed 48 bit integer stored in a 64 bit location aligned to
Peter Meerwald8b417d72012-06-12 15:31:27 +02001034 a 64 bit boundary. To obtain the clean value, shift right 2
Jonathan Cameronf386caa2010-11-22 23:31:16 +00001035 and apply a mask to zero the top 16 bits of the result.
Jonathan Cameron10ba8ea2010-09-21 14:41:08 +01001036 For other storage combinations this attribute will be extended
1037 appropriately.

1143 values should behave in the same way as a distance, i.e. lower
1144 values indicate something is closer to the sensor.
