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"

95Description:
96		Some devices have internal clocks.  This parameter sets the
97		resulting sampling frequency.  In many devices this
98		parameter has an effect on input filters etc. rather than
99		simply controlling when the input is sampled.  As this
100		affects data ready triggers, hardware buffers and the sysfs
101		direct access interfaces, it may be found in any of the
102		relevant directories.  If it affects all of the above
103		then it is to be found in the base device directory.

756		Event generated when channel passes a threshold in the specified

758		then either the device will report an event which ever direction
759		a single threshold value is passed in (e.g.
760		<type>[Y][_name]_<raw|input>_thresh_value) or
761		<type>[Y][_name]_<raw|input>_thresh_rising_value and
762		<type>[Y][_name]_<raw|input>_thresh_falling_value may take
763		different values, but the device can only enable both thresholds
764		or neither.
765
766		Note the driver will assume the last p events requested are
767		to be enabled where p is how many it supports (which may vary
768		depending on the exact set requested. So if you want to be
769		sure you have set what you think you have, check the contents of
770		these attributes after everything is configured. Drivers may
771		have to buffer any parameters so that they are consistent when

809Description:
810		Event generated when channel passes a threshold on the rate of
811		change (1st differential) in the specified (_rising|_falling)
812		direction. If the direction is not specified, then either the
813		device will report an event which ever direction a single
814		threshold value is passed in (e.g.
815		<type>[Y][_name]_<raw|input>_roc_value) or
816		<type>[Y][_name]_<raw|input>_roc_rising_value and
817		<type>[Y][_name]_<raw|input>_roc_falling_value may take
818		different values, but the device can only enable both rate of
819		change thresholds or neither.
820
821		Note the driver will assume the last p events requested are
822		to be enabled where p is however many it supports (which may
823		vary depending on the exact set requested. So if you want to be
824		sure you have set what you think you have, check the contents of
825		these attributes after everything is configured. Drivers may
826		have to buffer any parameters so that they are consistent when
827		a given event type is enabled a future point (and not those for
828		whatever event was previously enabled).

834Description:
835		Adaptive thresholds are similar to normal fixed thresholds
836		but the value is expressed as an offset from a value which
837		provides a low frequency approximation of the channel itself.
838		Thus these detect if a rapid change occurs in the specified
839		direction which crosses tracking value + offset.
840		Tracking value calculation is devices specific.

846Description:
847		When adaptive thresholds are used, the tracking signal
848		may adjust too slowly to step changes in the raw signal.
849		Thus these specify the time in seconds for which the
850		difference between the slow tracking signal and the raw
851		signal is allowed to remain out-of-range before a reset
852		event occurs in which the tracking signal is made equal
853		to the raw signal, allowing slow tracking to resume and the
854		adaptive threshold event detection to function as expected.

986Description:
987		Specifies the hysteresis of threshold that the device is comparing

990		If separate attributes exist for the two directions, but
991		direction is not specified for this attribute, then a single

993
994		For falling events the hysteresis is added to the _value attribute for
995		this event to get the upper threshold for when the event goes back to
996		normal, for rising events the hysteresis is subtracted from the _value
997		attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
998		and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
999		will get activated once in_voltage0_raw goes above 1200 and will become
1000		deactivated again once the value falls below 1150.

1346Description:
1347		Description of the scan element data storage within the buffer
1348		and hence the form in which it is read from user-space.
1349		Form is [be|le]:[s|u]bits/storagebits[>>shift].
1350		be or le specifies big or little endian. s or u specifies if
1351		signed (2's complement) or unsigned. bits is the number of bits
1352		of data and storagebits is the space (after padding) that it
1353		occupies in the buffer. shift if specified, is the shift that
1354		needs to be applied prior to masking out unused bits. Some
1355		devices put their data in the middle of the transferred elements
1356		with additional information on both sides.  Note that some
1357		devices will have additional information in the unused bits
1358		so to get a clean value, the bits value must be used to mask
1359		the buffer output value appropriately.  The storagebits value
1360		also specifies the data alignment.  So s48/64>>2 will be a
1361		signed 48 bit integer stored in a 64 bit location aligned to
1362		a 64 bit boundary. To obtain the clean value, shift right 2
1363		and apply a mask to zero the top 16 bits of the result.
1364		For other storage combinations this attribute will be extended
1365		appropriately.

1646		currently enabled or disabled. If the device does not have a
1647		hardware fifo this entry is not present.
1648		The hardware fifo is enabled when the buffer is enabled if the

1802Description:
1803		Mounting matrix for IIO sensors. This is a rotation matrix which
1804		informs userspace about sensor chip's placement relative to the
1805		main hardware it is mounted on.
1806
1807		Main hardware placement is defined according to the local
1808		reference frame related to the physical quantity the sensor
1809		measures.
1810
1811		Given that the rotation matrix is defined in a board specific
1812		way (platform data and / or device-tree), the main hardware
1813		reference frame definition is left to the implementor's choice
1814		(see below for a magnetometer example).
1815
1816		Applications should apply this rotation matrix to samples so
1817		that when main hardware reference frame is aligned onto local
1818		reference frame, then sensor chip reference frame is also
1819		perfectly aligned with it.
1820
1821		Matrix is a 3x3 unitary matrix and typically looks like
1822		[0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix
1823		[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware
1824		are perfectly aligned with each other.
1825
1826		For example, a mounting matrix for a magnetometer sensor informs
1827		userspace about sensor chip's ORIENTATION relative to the main
1828		hardware.
1829
1830		More specifically, main hardware orientation is defined with
1831		respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where :
1832
1833		* Y is in the ground plane and positive towards magnetic North ;
1834		* X is in the ground plane, perpendicular to the North axis and
1835		  positive towards the East ;
1836		* Z is perpendicular to the ground plane and positive upwards.
1837
1838		An implementor might consider that for a hand-held device, a
1839		'natural' orientation would be 'front facing camera at the top'.
1840		The main hardware reference frame could then be described as :
1841
1842		* Y is in the plane of the screen and is positive towards the
1843		  top of the screen ;
1844		* X is in the plane of the screen, perpendicular to Y axis, and
1845		  positive towards the right hand side of the screen ;
1846		* Z is perpendicular to the screen plane and positive out of the
1847		  screen.
1848
1849		Another example for a quadrotor UAV might be :
1850
1851		* Y is in the plane of the propellers and positive towards the
1852		  front-view camera;
1853		* X is in the plane of the propellers, perpendicular to Y axis,
1854		  and positive towards the starboard side of the UAV ;
1855		* Z is perpendicular to propellers plane and positive upwards.

1995KernelVersion:	5.8
1996Contact:	linux-iio@vger.kernel.org
1997Description:
1998		Some sensors have the ability to apply auto calibration at
1999		runtime. For example, it may be necessary to compensate for
2000		contaminant build-up in a measurement chamber or optical
2001		element deterioration that would otherwise lead to sensor drift.
2002
2003		Writing 1 or 0 to this attribute will respectively activate or
2004		deactivate this auto calibration function.
2005
2006		Upon reading, the current status is returned.

2011Contact:	linux-iio@vger.kernel.org
2012Description:
2013		Some sensors have the ability to apply a manual calibration using
2014		a known measurement value, perhaps obtained from an external
2015		reference device.
2016
2017		Writing a value to this function will force such a calibration
2018		change. For the scd30 the value should be from the range
2019		[400 1 2000].
2020
2021		Note for the scd30 that a valid value may only be obtained once
2022		it is has been written. Until then any read back of this value
2023		should be ignored. As for the scd4x an error will be returned
2024		immediately if the manual calibration has failed.
