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.

Jonathan Cameronf386caa2010-11-22 23:31:16 +0000266 May be writable if a variable offset can be applied on the
267 device. Note that this is different to calibbias which
268 is for devices (or drivers) that apply offsets to compensate
269 for variation between different instances of the part, typically
270 adjusted by using some hardware supported calibration procedure.
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100271 Calibbias is applied internally, offset is applied in userspace

736Description:
737 Specifies the hysteresis of threshold that the device is comparing
738 against for the events enabled by
739 <type>Y[_name]_thresh[_(rising|falling)]_hysteresis.
740 If separate attributes exist for the two directions, but
741 direction is not specified for this attribute, then a single
742 hysteresis value applies to both directions.
743 For falling events the hysteresis is added to the _value attribute for
744 this event to get the upper threshold for when the event goes back to
745 normal, for rising events the hysteresis is subtracted from the _value
746 attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
747 and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
748 will get activated once in_voltage0_raw goes above 1200 and will become
749 deactived again once the value falls below 1150.

785Description:
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000786 Specifies the value of rate of change threshold that the
787 device is comparing against for the events enabled by
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100788 <type>[Y][_name]_roc[_rising|falling]_en.
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000789 If separate attributes exist for the two directions,
790 but direction is not specified for this attribute,
791 then a single threshold value applies to both directions.
792 The raw or input element of the name indicates whether the
793 value is in raw device units or in processed units (as _raw
794 and _input do on sysfs direct channel read attributes).

Jonathan Cameron10ba8ea2010-09-21 14:41:08 +01001040 Description of the scan element data storage within the buffer
Jonathan Cameronf386caa2010-11-22 23:31:16 +00001041 and hence the form in which it is read from user-space.
Jonathan Cameron15739cd2011-09-21 11:15:51 +01001042 Form is [be|le]:[s|u]bits/storagebits[>>shift].
1043 be or le specifies big or little endian. s or u specifies if
Jonathan Cameronf386caa2010-11-22 23:31:16 +00001044 signed (2's complement) or unsigned. bits is the number of bits
1045 of data and storagebits is the space (after padding) that it
1046 occupies in the buffer. shift if specified, is the shift that
1047 needs to be applied prior to masking out unused bits. Some
1048 devices put their data in the middle of the transferred elements
1049 with additional information on both sides. Note that some
1050 devices will have additional information in the unused bits
1051 so to get a clean value, the bits value must be used to mask
1052 the buffer output value appropriately. The storagebits value
1053 also specifies the data alignment. So s48/64>>2 will be a
1054 signed 48 bit integer stored in a 64 bit location aligned to
Peter Meerwald8b417d72012-06-12 15:31:27 +02001055 a 64 bit boundary. To obtain the clean value, shift right 2
Jonathan Cameronf386caa2010-11-22 23:31:16 +00001056 and apply a mask to zero the top 16 bits of the result.

1165 values should behave in the same way as a distance, i.e. lower
1166 values indicate something is closer to the sensor.
