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.

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

1107	Description:
1108			Description of the scan element data storage within the buffer
1109			and hence the form in which it is read from user-space.
1110			Form is [be|le]:[s|u]bits/storagebits[>>shift].
1111			be or le specifies big or little endian. s or u specifies if
1112			signed (2's complement) or unsigned. bits is the number of bits
1113			of data and storagebits is the space (after padding) that it
1114			occupies in the buffer. shift if specified, is the shift that
1115			needs to be applied prior to masking out unused bits. Some
1116			devices put their data in the middle of the transferred elements
1117			with additional information on both sides.  Note that some
1118			devices will have additional information in the unused bits
1119			so to get a clean value, the bits value must be used to mask
1120			the buffer output value appropriately.  The storagebits value
1121			also specifies the data alignment.  So s48/64>>2 will be a
1122			signed 48 bit integer stored in a 64 bit location aligned to
1123			a 64 bit boundary. To obtain the clean value, shift right 2
1124			and apply a mask to zero the top 16 bits of the result.
1125			For other storage combinations this attribute will be extended
1126			appropriately.

1446	Description:
1447			The emissivity ratio of the surface in the field of view of the
1448			contactless temperature sensor.  Emissivity varies from 0 to 1,
1449			with 1 being the emissivity of a black body.

1456	Description:
1457			Hardware applied number of measurements for acquiring one
1458			data point. The HW will do <type>[_name]_oversampling_ratio
1459			measurements and return the average value as output data. Each
1460			value resulted from <type>[_name]_oversampling_ratio measurements
1461			is considered as one sample for <type>[_name]_sampling_frequency.
