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.

254 for variation between different instances of the part, typically
255 adjusted by using some hardware supported calibration procedure.
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100256 Calibbias is applied internally, offset is applied in userspace

545Description:
546 Event generated when channel passes a threshold on the rate of
547 change (1st differential) in the specified (_rising|_falling)
548 direction. If the direction is not specified, then either the
549 device will report an event which ever direction a single
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100550 threshold value is passed in (e.g.
551 <type>[Y][_name]_<raw|input>_roc_value) or
552 <type>[Y][_name]_<raw|input>_roc_rising_value and
553 <type>[Y][_name]_<raw|input>_roc_falling_value may take
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000554 different values, but the device can only enable both rate of
555 change thresholds or neither.
556 Note the driver will assume the last p events requested are
557 to be enabled where p is however many it supports (which may
558 vary depending on the exact set requested. So if you want to be
559 sure you have set what you think you have, check the contents of
560 these attributes after everything is configured. Drivers may
561 have to buffer any parameters so that they are consistent when
562 a given event type is enabled a future point (and not those for
563 whatever event was previously enabled).

667Description:
668 Specifies the hysteresis of threshold that the device is comparing
669 against for the events enabled by
670 <type>Y[_name]_thresh[_(rising|falling)]_hysteresis.
671 If separate attributes exist for the two directions, but
672 direction is not specified for this attribute, then a single
673 hysteresis value applies to both directions.
674 For falling events the hysteresis is added to the _value attribute for
675 this event to get the upper threshold for when the event goes back to
676 normal, for rising events the hysteresis is subtracted from the _value
677 attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
678 and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
679 will get activated once in_voltage0_raw goes above 1200 and will become
680 deactived again once the value falls below 1150.

Jonathan Cameron10ba8ea2010-09-21 14:41:08 +0100949 Description of the scan element data storage within the buffer
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000950 and hence the form in which it is read from user-space.
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100951 Form is [be|le]:[s|u]bits/storagebits[>>shift].
952 be or le specifies big or little endian. s or u specifies if
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000953 signed (2's complement) or unsigned. bits is the number of bits
954 of data and storagebits is the space (after padding) that it
955 occupies in the buffer. shift if specified, is the shift that
956 needs to be applied prior to masking out unused bits. Some
957 devices put their data in the middle of the transferred elements
958 with additional information on both sides. Note that some
959 devices will have additional information in the unused bits
960 so to get a clean value, the bits value must be used to mask
961 the buffer output value appropriately. The storagebits value
962 also specifies the data alignment. So s48/64>>2 will be a
963 signed 48 bit integer stored in a 64 bit location aligned to
Peter Meerwald8b417d72012-06-12 15:31:27 +0200964 a 64 bit boundary. To obtain the clean value, shift right 2
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000965 and apply a mask to zero the top 16 bits of the result.
Jonathan Cameron10ba8ea2010-09-21 14:41:08 +0100966 For other storage combinations this attribute will be extended
967 appropriately.

1109 Raw current measurement from channel X. Units are in milliamps
1110 after application of scale and offset. If no offset or scale is
1111 present, output should be considered as processed with the
1112 unit in milliamps.
