1	What:		/sys/bus/iio/devices/iio:deviceX
2	KernelVersion:	2.6.35
3	Contact:	linux-iio@vger.kernel.org
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.

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

279			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>.
282			May be writable if a variable offset can be applied on the

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.
287			Calibbias is applied internally, offset is applied in userspace
288			to the _raw output.

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

1111	Description:
1112			Description of the scan element data storage within the buffer
1113			and hence the form in which it is read from user-space.
1114			Form is [be|le]:[s|u]bits/storagebits[>>shift].
1115			be or le specifies big or little endian. s or u specifies if
1116			signed (2's complement) or unsigned. bits is the number of bits
1117			of data and storagebits is the space (after padding) that it
1118			occupies in the buffer. shift if specified, is the shift that
1119			needs to be applied prior to masking out unused bits. Some
1120			devices put their data in the middle of the transferred elements
1121			with additional information on both sides.  Note that some
1122			devices will have additional information in the unused bits
1123			so to get a clean value, the bits value must be used to mask
1124			the buffer output value appropriately.  The storagebits value
1125			also specifies the data alignment.  So s48/64>>2 will be a
1126			signed 48 bit integer stored in a 64 bit location aligned to
1127			a 64 bit boundary. To obtain the clean value, shift right 2
1128			and apply a mask to zero the top 16 bits of the result.
1129			For other storage combinations this attribute will be extended
1130			appropriately.

1445	Description:
1446			A list of positive integers specifying the available watermark
1447			levels for the hardware fifo. This entry is optional and if it
1448			is not present it means that all the values between
1449			hwfifo_watermark_min and hwfifo_watermark_max are supported.
1450			If the user sets buffer/watermark to a value greater than
1451			hwfifo_watermak_min but not equal to any of the values in this
1452			list, the driver will chose an appropriate value for the
1453			hardware fifo watermark level.

1523	Description:
1524			Mounting matrix for IIO sensors. This is a rotation matrix which
1525			informs userspace about sensor chip's placement relative to the
1526			main hardware it is mounted on.
1527			Main hardware placement is defined according to the local
1528			reference frame related to the physical quantity the sensor
1529			measures.
1530			Given that the rotation matrix is defined in a board specific
1531			way (platform data and / or device-tree), the main hardware
1532			reference frame definition is left to the implementor's choice
1533			(see below for a magnetometer example).
1534			Applications should apply this rotation matrix to samples so
1535			that when main hardware reference frame is aligned onto local
1536			reference frame, then sensor chip reference frame is also
1537			perfectly aligned with it.
1538			Matrix is a 3x3 unitary matrix and typically looks like
1539			[0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix
1540			[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware
1541			are perfectly aligned with each other.
1542	
1543			For example, a mounting matrix for a magnetometer sensor informs
1544			userspace about sensor chip's ORIENTATION relative to the main
1545			hardware.
1546			More specifically, main hardware orientation is defined with
1547			respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where :
1548			* Y is in the ground plane and positive towards magnetic North ;
1549			* X is in the ground plane, perpendicular to the North axis and
1550			  positive towards the East ;
1551			* Z is perpendicular to the ground plane and positive upwards.
1552	
1553			An implementor might consider that for a hand-held device, a
1554			'natural' orientation would be 'front facing camera at the top'.
1555			The main hardware reference frame could then be described as :
1556			* Y is in the plane of the screen and is positive towards the
1557			  top of the screen ;
1558			* X is in the plane of the screen, perpendicular to Y axis, and
1559			  positive towards the right hand side of the screen ;
1560			* Z is perpendicular to the screen plane and positive out of the
1561			  screen.
1562			Another example for a quadrotor UAV might be :
1563			* Y is in the plane of the propellers and positive towards the
1564			  front-view camera;
1565			* X is in the plane of the propellers, perpendicular to Y axis,
1566			  and positive towards the starboard side of the UAV ;
1567			* Z is perpendicular to propellers plane and positive upwards.
