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.

245 is for devices (or drivers) that apply offsets to compensate
246 for variation between different instances of the part, typically
247 adjusted by using some hardware supported calibration procedure.
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100248 Calibbias is applied internally, offset is applied in userspace

523Description:
524 Event generated when channel passes a threshold on the rate of
525 change (1st differential) in the specified (_rising|_falling)
526 direction. If the direction is not specified, then either the
527 device will report an event which ever direction a single
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100528 threshold value is passed in (e.g.
529 <type>[Y][_name]_<raw|input>_roc_value) or
530 <type>[Y][_name]_<raw|input>_roc_rising_value and
531 <type>[Y][_name]_<raw|input>_roc_falling_value may take
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000532 different values, but the device can only enable both rate of
533 change thresholds or neither.
534 Note the driver will assume the last p events requested are
535 to be enabled where p is however many it supports (which may
536 vary depending on the exact set requested. So if you want to be
537 sure you have set what you think you have, check the contents of
538 these attributes after everything is configured. Drivers may
539 have to buffer any parameters so that they are consistent when
540 a given event type is enabled a future point (and not those for
541 whatever event was previously enabled).

645Description:
646 Specifies the hysteresis of threshold that the device is comparing
647 against for the events enabled by
648 <type>Y[_name]_thresh[_(rising|falling)]_hysteresis.
649 If separate attributes exist for the two directions, but
650 direction is not specified for this attribute, then a single
651 hysteresis value applies to both directions.
652 For falling events the hysteresis is added to the _value attribute for
653 this event to get the upper threshold for when the event goes back to
654 normal, for rising events the hysteresis is subtracted from the _value
655 attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
656 and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
657 will get activated once in_voltage0_raw goes above 1200 and will become
658 deactived again once the value falls below 1150.

885Description:
Jonathan Cameron10ba8ea2010-09-21 14:41:08 +0100886 Description of the scan element data storage within the buffer
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000887 and hence the form in which it is read from user-space.
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100888 Form is [be|le]:[s|u]bits/storagebits[>>shift].
889 be or le specifies big or little endian. s or u specifies if
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000890 signed (2's complement) or unsigned. bits is the number of bits
891 of data and storagebits is the space (after padding) that it
892 occupies in the buffer. shift if specified, is the shift that
893 needs to be applied prior to masking out unused bits. Some
894 devices put their data in the middle of the transferred elements
895 with additional information on both sides. Note that some
896 devices will have additional information in the unused bits
897 so to get a clean value, the bits value must be used to mask
898 the buffer output value appropriately. The storagebits value
899 also specifies the data alignment. So s48/64>>2 will be a
900 signed 48 bit integer stored in a 64 bit location aligned to
Peter Meerwald8b417d72012-06-12 15:31:27 +0200901 a 64 bit boundary. To obtain the clean value, shift right 2
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000902 and apply a mask to zero the top 16 bits of the result.
Jonathan Cameron10ba8ea2010-09-21 14:41:08 +0100903 For other storage combinations this attribute will be extended
904 appropriately.
