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.

275Description:
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000276 If known for a device, offset to be added to <type>[Y]_raw prior
277 to scaling by <type>[Y]_scale in order to obtain value in the
Peter Meerwald8b417d72012-06-12 15:31:27 +0200278 <type> units as specified in <type>[Y]_raw documentation.
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100279 Not present if the offset is always 0 or unknown. If Y or
280 axis <x|y|z> is not present, then the offset applies to all
281 in channels of <type>.
Jonathan Cameronf386caa2010-11-22 23:31:16 +0000282 May be writable if a variable offset can be applied on the
283 device. Note that this is different to calibbias which
284 is for devices (or drivers) that apply offsets to compensate
285 for variation between different instances of the part, typically
286 adjusted by using some hardware supported calibration procedure.
Jonathan Cameron15739cd2011-09-21 11:15:51 +0100287 Calibbias is applied internally, offset is applied in userspace
288 to the _raw output.

778Description:
779 Specifies the hysteresis of threshold that the device is comparing
780 against for the events enabled by
781 <type>Y[_name]_thresh[_(rising|falling)]_hysteresis.
782 If separate attributes exist for the two directions, but
783 direction is not specified for this attribute, then a single
784 hysteresis value applies to both directions.
785 For falling events the hysteresis is added to the _value attribute for
786 this event to get the upper threshold for when the event goes back to
787 normal, for rising events the hysteresis is subtracted from the _value
788 attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
789 and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
790 will get activated once in_voltage0_raw goes above 1200 and will become
791 deactived again once the value falls below 1150.

Jonathan Cameron10ba8ea2010-09-21 14:41:08 +01001110 Description of the scan element data storage within the buffer
Jonathan Cameronf386caa2010-11-22 23:31:16 +00001111 and hence the form in which it is read from user-space.
Jonathan Cameron15739cd2011-09-21 11:15:51 +01001112 Form is [be|le]:[s|u]bits/storagebits[>>shift].
1113 be or le specifies big or little endian. s or u specifies if
Jonathan Cameronf386caa2010-11-22 23:31:16 +00001114 signed (2's complement) or unsigned. bits is the number of bits
1115 of data and storagebits is the space (after padding) that it
1116 occupies in the buffer. shift if specified, is the shift that
1117 needs to be applied prior to masking out unused bits. Some
1118 devices put their data in the middle of the transferred elements
1119 with additional information on both sides. Note that some
1120 devices will have additional information in the unused bits
1121 so to get a clean value, the bits value must be used to mask
1122 the buffer output value appropriately. The storagebits value
1123 also specifies the data alignment. So s48/64>>2 will be a
1124 signed 48 bit integer stored in a 64 bit location aligned to
Peter Meerwald8b417d72012-06-12 15:31:27 +02001125 a 64 bit boundary. To obtain the clean value, shift right 2
Jonathan Cameronf386caa2010-11-22 23:31:16 +00001126 and apply a mask to zero the top 16 bits of the result.
Jonathan Cameron10ba8ea2010-09-21 14:41:08 +01001127 For other storage combinations this attribute will be extended
1128 appropriately.

1323Description:
Irina Tirdea40cb7612015-01-29 18:45:10 +00001324 Activates a device feature that runs in firmware/hardware.
1325 E.g. for steps: the pedometer saves power while not used;
1326 when activated, it will count the steps taken by the user in
1327 firmware and export them through in_steps_input.

1361KernelVersion: 4.2
1362Contact: linux-iio@vger.kernel.org
1363Description:
1364 A single positive integer specifying the maximum number of scan
1365 elements to wait for.
1366 Poll will block until the watermark is reached.
1367 Blocking read will wait until the minimum between the requested
1368 read amount or the low water mark is available.
1369 Non-blocking read will retrieve the available samples from the
1370 buffer even if there are less samples then watermark level. This
1371 allows the application to block on poll with a timeout and read
1372 the available samples after the timeout expires and thus have a
1373 maximum delay guarantee.

1376KernelVersion: 4.2
1377Contact: linux-iio@vger.kernel.org
1378Description:
1379 A read-only boolean value that indicates if the hardware fifo is
1380 currently enabled or disabled. If the device does not have a
1381 hardware fifo this entry is not present.
1382 The hardware fifo is enabled when the buffer is enabled if the
1383 current hardware fifo watermark level is set and other current
1384 device settings allows it (e.g. if a trigger is set that samples
1385 data differently that the hardware fifo does then hardware fifo
1386 will not enabled).
1387 If the hardware fifo is enabled and the level of the hardware
1388 fifo reaches the hardware fifo watermark level the device will
1389 flush its hardware fifo to the device buffer. Doing a non
1390 blocking read on the device when no samples are present in the
1391 device buffer will also force a flush.
1392 When the hardware fifo is enabled there is no need to use a
1393 trigger to use buffer mode since the watermark settings
1394 guarantees that the hardware fifo is flushed to the device
1395 buffer.

1400Description:
1401 Read-only entry that contains a single integer specifying the
1402 current watermark level for the hardware fifo. If the device
1403 does not have a hardware fifo this entry is not present.
1404 The watermark level for the hardware fifo is set by the driver
1405 based on the value set by the user in buffer/watermark but
1406 taking into account hardware limitations (e.g. most hardware
1407 buffers are limited to 32-64 samples, some hardware buffers
1408 watermarks are fixed or have minimum levels). A value of 0
1409 means that the hardware watermark is unset.

1414Description:
1415 A single positive integer specifying the minimum watermark level
1416 for the hardware fifo of this device. If the device does not
1417 have a hardware fifo this entry is not present.
1418 If the user sets buffer/watermark to a value less than this one,
1419 then the hardware watermark will remain unset.

1424Description:
1425 A single positive integer specifying the maximum watermark level
1426 for the hardware fifo of this device. If the device does not
1427 have a hardware fifo this entry is not present.
1428 If the user sets buffer/watermark to a value greater than this
1429 one, then the hardware watermark will be capped at this value.

1434Description:
1435 A list of positive integers specifying the available watermark
1436 levels for the hardware fifo. This entry is optional and if it
1437 is not present it means that all the values between
1438 hwfifo_watermark_min and hwfifo_watermark_max are supported.
1439 If the user sets buffer/watermark to a value greater than
1440 hwfifo_watermak_min but not equal to any of the values in this
1441 list, the driver will chose an appropriate value for the
1442 hardware fifo watermark level.
