12Description:
13		An event driven driver of data capture to an in kernel buffer.

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.

47Description:
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.

806Description:
807		Specifies the hysteresis of threshold that the device is comparing
808		against for the events enabled by
809		<type>Y[_name]_thresh[_(rising|falling)]_hysteresis.
810		If separate attributes exist for the two directions, but
811		direction is not specified for this attribute, then a single
812		hysteresis value applies to both directions.
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.

1130Description:
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.

1413		The hardware fifo is enabled when the buffer is enabled if the

1554Description:
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.
