4	Description:
5			Hardware chip or device accessed by one communication port.
6			Corresponds to a grouping of sensor channels. X is the IIO
7			index of the device.

9	What:		/sys/bus/iio/devices/triggerX
10	KernelVersion:	2.6.35
11	Contact:	linux-iio@vger.kernel.org
12	Description:
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			Contains trigger type specific elements. These do not
19			generalize well and hence are not documented in this file.
20			X is the IIO index of the trigger.

44	What:		/sys/bus/iio/devices/triggerX/sampling_frequency
45	KernelVersion:	2.6.35
46	Contact:	linux-iio@vger.kernel.org
47	Description:
48			Some devices have internal clocks.  This parameter sets the
49			resulting sampling frequency.  In many devices this
50			parameter has an effect on input filters etc. rather than
51			simply controlling when the input is sampled.  As this
52			effects data ready triggers, hardware buffers and the sysfs
53			direct access interfaces, it may be found in any of the
54			relevant directories.  If it effects all of the above
55			then it is to be found in the base device directory.

286			Not present if the offset is always 0 or unknown. If Y or

289			May be writable if a variable offset can be applied on the

291			is for devices (or drivers) that apply offsets to compensate
292			for variation between different instances of the part, typically
293			adjusted by using some hardware supported calibration procedure.
294			Calibbias is applied internally, offset is applied in userspace
295			to the _raw output.

795			Specifies the hysteresis of threshold that the device is comparing
796			against for the events enabled by
797			<type>Y[_name]_thresh[_(rising|falling)]_hysteresis.
798			If separate attributes exist for the two directions, but
799			direction is not specified for this attribute, then a single
800			hysteresis value applies to both directions.
801			For falling events the hysteresis is added to the _value attribute for
802			this event to get the upper threshold for when the event goes back to
803			normal, for rising events the hysteresis is subtracted from the _value
804			attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
805			and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
806			will get activated once in_voltage0_raw goes above 1200 and will become
807			deactived again once the value falls below 1150.

1118	Description:
1119			Description of the scan element data storage within the buffer
1120			and hence the form in which it is read from user-space.
1121			Form is [be|le]:[s|u]bits/storagebits[>>shift].
1122			be or le specifies big or little endian. s or u specifies if
1123			signed (2's complement) or unsigned. bits is the number of bits
1124			of data and storagebits is the space (after padding) that it
1125			occupies in the buffer. shift if specified, is the shift that
1126			needs to be applied prior to masking out unused bits. Some
1127			devices put their data in the middle of the transferred elements
1128			with additional information on both sides.  Note that some
1129			devices will have additional information in the unused bits
1130			so to get a clean value, the bits value must be used to mask
1131			the buffer output value appropriately.  The storagebits value
1132			also specifies the data alignment.  So s48/64>>2 will be a
1133			signed 48 bit integer stored in a 64 bit location aligned to
1134			a 64 bit boundary. To obtain the clean value, shift right 2
1135			and apply a mask to zero the top 16 bits of the result.
1136			For other storage combinations this attribute will be extended
1137			appropriately.

1452	Description:
1453			A list of positive integers specifying the available watermark
1454			levels for the hardware fifo. This entry is optional and if it
1455			is not present it means that all the values between

1457			If the user sets buffer/watermark to a value greater than
1458			hwfifo_watermak_min but not equal to any of the values in this
1459			list, the driver will chose an appropriate value for the
1460			hardware fifo watermark level.

1530	Description:
1531			Mounting matrix for IIO sensors. This is a rotation matrix which
1532			informs userspace about sensor chip's placement relative to the
1533			main hardware it is mounted on.
1534			Main hardware placement is defined according to the local
1535			reference frame related to the physical quantity the sensor
1536			measures.
1537			Given that the rotation matrix is defined in a board specific
1538			way (platform data and / or device-tree), the main hardware
1539			reference frame definition is left to the implementor's choice
1540			(see below for a magnetometer example).
1541			Applications should apply this rotation matrix to samples so
1542			that when main hardware reference frame is aligned onto local
1543			reference frame, then sensor chip reference frame is also
1544			perfectly aligned with it.
1545			Matrix is a 3x3 unitary matrix and typically looks like
1546			[0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix
1547			[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware
1548			are perfectly aligned with each other.
1549	
1550			For example, a mounting matrix for a magnetometer sensor informs
1551			userspace about sensor chip's ORIENTATION relative to the main
1552			hardware.
1553			More specifically, main hardware orientation is defined with
1554			respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where :
1555			* Y is in the ground plane and positive towards magnetic North ;
1556			* X is in the ground plane, perpendicular to the North axis and
1557			  positive towards the East ;
1558			* Z is perpendicular to the ground plane and positive upwards.
1559	
1560			An implementor might consider that for a hand-held device, a
1561			'natural' orientation would be 'front facing camera at the top'.
1562			The main hardware reference frame could then be described as :
1563			* Y is in the plane of the screen and is positive towards the
1564			  top of the screen ;
1565			* X is in the plane of the screen, perpendicular to Y axis, and
1566			  positive towards the right hand side of the screen ;
1567			* Z is perpendicular to the screen plane and positive out of the
1568			  screen.
1569			Another example for a quadrotor UAV might be :
1570			* Y is in the plane of the propellers and positive towards the
1571			  front-view camera;
1572			* X is in the plane of the propellers, perpendicular to Y axis,
1573			  and positive towards the starboard side of the UAV ;
1574			* Z is perpendicular to propellers plane and positive upwards.
