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.
17		periodic timer, GPIO or high resolution timer).
18
19		Contains trigger type specific elements. These do not
20		generalize well and hence are not documented in this file.
21		X is the IIO index of the trigger.

33		Description of the physical chip / device for device X.
34		Typically a part number.
35
36What:		/sys/bus/iio/devices/iio:deviceX/label
37KernelVersion:	5.8
38Contact:	linux-iio@vger.kernel.org
39Description:
40		Optional symbolic label for a device.
41		This is useful for userspace to be able to better identify an
42		individual device.
43
44		The contents of the label are free-form, but there are some
45		standardized uses:
46
47		For proximity sensors which give the proximity (of a person) to
48		a certain wlan or wwan antenna the following standardized labels
49		are used:
50
51		* "proximity-wifi"
52		* "proximity-lte"
53		* "proximity-wifi-lte"
54		* "proximity-wifi-left"
55		* "proximity-wifi-right"
56
57		These are used to indicate to userspace that these proximity
58		sensors may be used to tune transmit power to ensure that
59		Specific Absorption Rate (SAR) limits are honored.
60		The "-left" and "-right" labels are for devices with multiple
61		antennas.
62
63		In some laptops/tablets the standardized proximity sensor labels
64		instead	indicate proximity to a specific part of the device:
65
66		* "proximity-palmrest" indicates proximity to the keyboard's palmrest
67		* "proximity-palmrest-left" indicates proximity to the left part of the palmrest
68		* "proximity-palmrest-right" indicates proximity to the right part of the palmrest
69		* "proximity-lap" indicates the device is being used on someone's lap
70
71		Note "proximity-lap" is special in that its value may be
72		calculated by firmware from other sensor readings, rather then
73		being a raw sensor reading.
74
75		For accelerometers used in 2-in-1s with 360° (yoga-style) hinges,
76		which have an accelerometer in both their base and their display,
77		the following standardized labels are used:
78
79		* "accel-base"
80		* "accel-display"
81
82		For devices where an accelerometer is housed in the swivel camera subassembly
83		(for AR application), the following standardized label is used:
84
85		* "accel-camera"

99KernelVersion:	2.6.35
100Contact:	linux-iio@vger.kernel.org
101Description:
102		Some devices have internal clocks.  This parameter sets the
103		resulting sampling frequency.  In many devices this
104		parameter has an effect on input filters etc. rather than
105		simply controlling when the input is sampled.  As this
106		affects data ready triggers, hardware buffers and the sysfs
107		direct access interfaces, it may be found in any of the
108		relevant directories.  If it affects all of the above
109		then it is to be found in the base device directory.
110
111		The stm32-timer-trigger has the additional characteristic that
112		a sampling_frequency of 0 is defined to stop sampling.

121Description:
122		When the internal sampling clock can only take a specific set of
123		frequencies, we can specify the available values with:
124
125		- a small discrete set of values like "0 2 4 6 8"
126		- a range with minimum, step and maximum frequencies like
127		  "[min step max]"

151		unique to allow association with event codes. Units after
152		application of scale and offset are millivolts.
153
154		Channels with 'i' and 'q' modifiers always exist in pairs and both
155		channels refer to the same signal. The 'i' channel contains the in-phase
156		component of the signal while the 'q' channel contains the quadrature
157		component.

217Contact:	linux-iio@vger.kernel.org
218Description:
219		For differential channels, this an offset that is applied
220		equally to both inputs. As the reading is of the difference
221		between the two inputs, this should not be applied to the _raw
222		reading by userspace (unlike _offset) and unlike calibbias
223		it does not affect the differential value measured because
224		the effect of _zeropoint cancels out across the two inputs
225		that make up the differential pair. It's purpose is to bring
226		the individual signals, before the differential is measured,
227		within the measurement range of the device. The naming is
228		chosen because if the separate inputs that make the
229		differential pair are drawn on a graph in their
230		_raw  units, this is the value that the zero point on the
231		measurement axis represents. It is expressed with the
232		same scaling as _raw.

244		If an axis is specified it generally means that the temperature
245		sensor is associated with one part of a compound device (e.g.
246		a gyroscope axis). The ambient and object modifiers distinguish

455Description:
456		If known for a device, offset to be added to <type>[Y]_raw prior
457		to scaling by <type>[Y]_scale in order to obtain value in the
458		<type> units as specified in <type>[Y]_raw documentation.
459		Not present if the offset is always 0 or unknown. If Y or
460		axis <x|y|z> is not present, then the offset applies to all
461		in channels of <type>.
462		May be writable if a variable offset can be applied on the
463		device. Note that this is different to calibbias which
464		is for devices (or drivers) that apply offsets to compensate
465		for variation between different instances of the part, typically
466		adjusted by using some hardware supported calibration procedure.
467		Calibbias is applied internally, offset is applied in userspace
468		to the _raw output.

810Description:
811		Output frequency for channel Y in Hz. The number must always be
812		specified and unique if the output corresponds to a single
813		channel.
814		Some drivers have additional constraints:
815		ADF4371 has an integrated VCO with fundamendal output
816		frequency ranging from 4000000000 Hz 8000000000 Hz.
817
818		out_altvoltage0_frequency:
819			A divide by 1, 2, 4, 8, 16, 32 or circuit generates
820			frequencies from 62500000 Hz to 8000000000 Hz.
821		out_altvoltage1_frequency:
822			This channel duplicates the channel 0 frequency
823		out_altvoltage2_frequency:
824			A frequency doubler generates frequencies from
825			8000000000 Hz to 16000000000 Hz.
826		out_altvoltage3_frequency:
827			A frequency quadrupler generates frequencies from
828			16000000000 Hz to 32000000000 Hz.
829
830		Note: writes to one of the channels will affect the frequency of
831		all the other channels, since it involves changing the VCO
832		fundamental output frequency.

982Description:
983		Adaptive thresholds are similar to normal fixed thresholds
984		but the value is expressed as an offset from a value which
985		provides a low frequency approximation of the channel itself.
986		Thus these detect if a rapid change occurs in the specified
987		direction which crosses tracking value + offset.

994Description:
995		When adaptive thresholds are used, the tracking signal
996		may adjust too slowly to step changes in the raw signal.
997		Thus these specify the time in seconds for which the
998		difference between the slow tracking signal and the raw
999		signal is allowed to remain out-of-range before a reset
1000		event occurs in which the tracking signal is made equal
1001		to the raw signal, allowing slow tracking to resume and the
1002		adaptive threshold event detection to function as expected.

1143		this event to get the upper threshold for when the event goes back to
1144		normal, for rising events the hysteresis is subtracted from the _value
1145		attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
1146		and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
1147		will get activated once in_voltage0_raw goes above 1200 and will become
1148		deactivated again once the value falls below 1150.

1494Description:
1495		Description of the scan element data storage within the buffer
1496		and hence the form in which it is read from user-space.
1497		Form is [be|le]:[s|u]bits/storagebits[>>shift].
1498		be or le specifies big or little endian. s or u specifies if
1499		signed (2's complement) or unsigned. bits is the number of bits
1500		of data and storagebits is the space (after padding) that it
1501		occupies in the buffer. shift if specified, is the shift that
1502		needs to be applied prior to masking out unused bits. Some
1503		devices put their data in the middle of the transferred elements
1504		with additional information on both sides.  Note that some
1505		devices will have additional information in the unused bits
1506		so to get a clean value, the bits value must be used to mask
1507		the buffer output value appropriately.  The storagebits value
1508		also specifies the data alignment.  So s48/64>>2 will be a
1509		signed 48 bit integer stored in a 64 bit location aligned to
1510		a 64 bit boundary. To obtain the clean value, shift right 2
1511		and apply a mask to zero the top 16 bits of the result.
1512		For other storage combinations this attribute will be extended
1513		appropriately.

1971Description:
1972		Mounting matrix for IIO sensors. This is a rotation matrix which
1973		informs userspace about sensor chip's placement relative to the
1974		main hardware it is mounted on.
1975
1976		Main hardware placement is defined according to the local
1977		reference frame related to the physical quantity the sensor
1978		measures.
1979
1980		Given that the rotation matrix is defined in a board specific
1981		way (platform data and / or device-tree), the main hardware
1982		reference frame definition is left to the implementor's choice
1983		(see below for a magnetometer example).
1984
1985		Applications should apply this rotation matrix to samples so
1986		that when main hardware reference frame is aligned onto local
1987		reference frame, then sensor chip reference frame is also
1988		perfectly aligned with it.
1989
1990		Matrix is a 3x3 unitary matrix and typically looks like
1991		[0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix
1992		[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware
1993		are perfectly aligned with each other.
1994
1995		For example, a mounting matrix for a magnetometer sensor informs
1996		userspace about sensor chip's ORIENTATION relative to the main
1997		hardware.
1998
1999		More specifically, main hardware orientation is defined with
2000		respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where :
2001
2002		* Y is in the ground plane and positive towards magnetic North ;
2003		* X is in the ground plane, perpendicular to the North axis and
2004		  positive towards the East ;
2005		* Z is perpendicular to the ground plane and positive upwards.
2006
2007		An implementor might consider that for a hand-held device, a
2008		'natural' orientation would be 'front facing camera at the top'.
2009		The main hardware reference frame could then be described as :
2010
2011		* Y is in the plane of the screen and is positive towards the
2012		  top of the screen ;
2013		* X is in the plane of the screen, perpendicular to Y axis, and
2014		  positive towards the right hand side of the screen ;
2015		* Z is perpendicular to the screen plane and positive out of the
2016		  screen.
2017
2018		Another example for a quadrotor UAV might be :
2019
2020		* Y is in the plane of the propellers and positive towards the
2021		  front-view camera;
2022		* X is in the plane of the propellers, perpendicular to Y axis,
2023		  and positive towards the starboard side of the UAV ;
2024		* Z is perpendicular to propellers plane and positive upwards.
