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.

537Description:
538 Event generated when channel passes a threshold on the rate of
539 change (1st differential) in the specified (_rising|_falling)
540 direction. If the direction is not specified, then either the
541 device will report an event which ever direction a single
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100542 threshold value is passed in (e.g.
543 <type>[Y][_name]_<raw|input>_roc_value) or
544 <type>[Y][_name]_<raw|input>_roc_rising_value and
545 <type>[Y][_name]_<raw|input>_roc_falling_value may take
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000546 different values, but the device can only enable both rate of
547 change thresholds or neither.
548 Note the driver will assume the last p events requested are
549 to be enabled where p is however many it supports (which may
550 vary depending on the exact set requested. So if you want to be
551 sure you have set what you think you have, check the contents of
552 these attributes after everything is configured. Drivers may
553 have to buffer any parameters so that they are consistent when
554 a given event type is enabled a future point (and not those for
555 whatever event was previously enabled).

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

Jonathan Cameron10ba8ea2010-09-21 14:41:08 +0100941 Description of the scan element data storage within the buffer
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000942 and hence the form in which it is read from user-space.
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100943 Form is [be|le]:[s|u]bits/storagebits[>>shift].
944 be or le specifies big or little endian. s or u specifies if
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000945 signed (2's complement) or unsigned. bits is the number of bits
946 of data and storagebits is the space (after padding) that it
947 occupies in the buffer. shift if specified, is the shift that
948 needs to be applied prior to masking out unused bits. Some
949 devices put their data in the middle of the transferred elements
950 with additional information on both sides. Note that some
951 devices will have additional information in the unused bits
952 so to get a clean value, the bits value must be used to mask
953 the buffer output value appropriately. The storagebits value
954 also specifies the data alignment. So s48/64>>2 will be a
955 signed 48 bit integer stored in a 64 bit location aligned to
Peter Meerwald8b417d72012-06-12 15:31:27 +0200956 a 64 bit boundary. To obtain the clean value, shift right 2
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000957 and apply a mask to zero the top 16 bits of the result.
Jonathan Cameron10ba8ea2010-09-21 14:41:08 +0100958 For other storage combinations this attribute will be extended
959 appropriately.

1081Description:
1082 Raw value of quaternion components using a format
1083 x y z w. Here x, y, and z component represents the axis about
1084 which a rotation will occur and w component represents the
1085 amount of rotation.

1101 Raw current measurement from channel X. Units are in milliamps
1102 after application of scale and offset. If no offset or scale is
1103 present, output should be considered as processed with the
1104 unit in milliamps.
