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.

43	What:		/sys/bus/iio/devices/iio:deviceX/buffer/sampling_frequency
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.

297			Not present if the offset is always 0 or unknown. If Y or
298			axis <x|y|z> is not present, then the offset applies to all
299			in channels of <type>.
300			May be writable if a variable offset can be applied on the
301			device. Note that this is different to calibbias which
302			is for devices (or drivers) that apply offsets to compensate
303			for variation between different instances of the part, typically
304			adjusted by using some hardware supported calibration procedure.
305			Calibbias is applied internally, offset is applied in userspace
306			to the _raw output.

807			Specifies the hysteresis of threshold that the device is comparing

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

813			For falling events the hysteresis is added to the _value attribute for
814			this event to get the upper threshold for when the event goes back to
815			normal, for rising events the hysteresis is subtracted from the _value
816			attribute. E.g. if in_voltage0_raw_thresh_rising_value is set to 1200
817			and in_voltage0_raw_thresh_rising_hysteresis is set to 50. The event
818			will get activated once in_voltage0_raw goes above 1200 and will become
819			deactivated again once the value falls below 1150.

1130	Description:
1131			Description of the scan element data storage within the buffer
1132			and hence the form in which it is read from user-space.
1133			Form is [be|le]:[s|u]bits/storagebits[>>shift].
1134			be or le specifies big or little endian. s or u specifies if
1135			signed (2's complement) or unsigned. bits is the number of bits
1136			of data and storagebits is the space (after padding) that it
1137			occupies in the buffer. shift if specified, is the shift that
1138			needs to be applied prior to masking out unused bits. Some
1139			devices put their data in the middle of the transferred elements
1140			with additional information on both sides.  Note that some
1141			devices will have additional information in the unused bits
1142			so to get a clean value, the bits value must be used to mask
1143			the buffer output value appropriately.  The storagebits value
1144			also specifies the data alignment.  So s48/64>>2 will be a
1145			signed 48 bit integer stored in a 64 bit location aligned to
1146			a 64 bit boundary. To obtain the clean value, shift right 2
1147			and apply a mask to zero the top 16 bits of the result.
1148			For other storage combinations this attribute will be extended
1149			appropriately.

1440	KernelVersion: 4.2
1441	Contact:	linux-iio@vger.kernel.org
1442	Description:
1443			Read-only entry that contains a single integer specifying the
1444			current watermark level for the hardware fifo. If the device
1445			does not have a hardware fifo this entry is not present.
1446			The watermark level for the hardware fifo is set by the driver
1447			based on the value set by the user in buffer/watermark but
1448			taking into account hardware limitations (e.g. most hardware
1449			buffers are limited to 32-64 samples, some hardware buffers
1450			watermarks are fixed or have minimum levels).  A value of 0
1451			means that the hardware watermark is unset.

1458			for the hardware fifo of this device. If the device does not
1459			have a hardware fifo this entry is not present.
1460			If the user sets buffer/watermark to a value less than this one,

1468			for the hardware fifo of this device. If the device does not
1469			have a hardware fifo this entry is not present.
1470			If the user sets buffer/watermark to a value greater than this
1471			one, then the hardware watermark will be capped at this value.

1476	Description:

1478			levels for the hardware fifo. This entry is optional and if it
1479			is not present it means that all the values between
1480			hwfifo_watermark_min and hwfifo_watermark_max are supported.
1481			If the user sets buffer/watermark to a value greater than
1482			hwfifo_watermak_min but not equal to any of the values in this
1483			list, the driver will chose an appropriate value for the

1554	Description:
1555			Mounting matrix for IIO sensors. This is a rotation matrix which
1556			informs userspace about sensor chip's placement relative to the
1557			main hardware it is mounted on.
1558			Main hardware placement is defined according to the local
1559			reference frame related to the physical quantity the sensor
1560			measures.
1561			Given that the rotation matrix is defined in a board specific
1562			way (platform data and / or device-tree), the main hardware
1563			reference frame definition is left to the implementor's choice
1564			(see below for a magnetometer example).
1565			Applications should apply this rotation matrix to samples so
1566			that when main hardware reference frame is aligned onto local
1567			reference frame, then sensor chip reference frame is also
1568			perfectly aligned with it.
1569			Matrix is a 3x3 unitary matrix and typically looks like
1570			[0, 1, 0; 1, 0, 0; 0, 0, -1]. Identity matrix
1571			[1, 0, 0; 0, 1, 0; 0, 0, 1] means sensor chip and main hardware
1572			are perfectly aligned with each other.
1573	
1574			For example, a mounting matrix for a magnetometer sensor informs
1575			userspace about sensor chip's ORIENTATION relative to the main
1576			hardware.
1577			More specifically, main hardware orientation is defined with
1578			respect to the LOCAL EARTH GEOMAGNETIC REFERENCE FRAME where :
1579			* Y is in the ground plane and positive towards magnetic North ;
1580			* X is in the ground plane, perpendicular to the North axis and
1581			  positive towards the East ;
1582			* Z is perpendicular to the ground plane and positive upwards.
1583	
1584			An implementor might consider that for a hand-held device, a
1585			'natural' orientation would be 'front facing camera at the top'.
1586			The main hardware reference frame could then be described as :
1587			* Y is in the plane of the screen and is positive towards the
1588			  top of the screen ;
1589			* X is in the plane of the screen, perpendicular to Y axis, and
1590			  positive towards the right hand side of the screen ;
1591			* Z is perpendicular to the screen plane and positive out of the
1592			  screen.
1593			Another example for a quadrotor UAV might be :
1594			* Y is in the plane of the propellers and positive towards the
1595			  front-view camera;
1596			* X is in the plane of the propellers, perpendicular to Y axis,
1597			  and positive towards the starboard side of the UAV ;
1598			* Z is perpendicular to propellers plane and positive upwards.
