What:		/sys/bus/iio/devices/triggerX
KernelVersion:	2.6.35
Contact:	linux-iio@vger.kernel.org
Description:
		An event driven driver of data capture to an in kernel buffer.
		May be provided by a device driver that also has an IIO device
		based on hardware generated events (e.g. data ready) or
		provided by a separate driver for other hardware (e.g.
		periodic timer, GPIO or high resolution timer).
		Contains trigger type specific elements. These do not
		generalize well and hence are not documented in this file.
		X is the IIO index of the trigger.

What:		/sys/bus/iio/devices/deviceX/sampling_frequency
KernelVersion:	2.6.35
Contact:	linux-iio@vger.kernel.org
Description:
		Some devices have internal clocks.  This parameter sets the
		resulting sampling frequency.  In many devices this
		parameter has an effect on input filters etc rather than
		simply controlling when the input is sampled.  As this
		effects datardy triggers, hardware buffers and the sysfs
		direct access interfaces, it may be found in any of the
		relevant directories.  If it effects all of the above
		then it is to be found in the base device directory as here.

		present, then the offset applies to all in channels of <type>.
		May be writable if a variable offset can be applied on the
		device. Note that this is different to calibbias which
		is for devices (or drivers) that apply offsets to compensate
		for variation between different instances of the part, typically
		adjusted by using some hardware supported calibration procedure.

Description:
		Event generated when channel passes a threshold in the specified

		<type>[Z][_name]_<raw|input>_thresh_falling_value may take
		different values, but the device can only enable both thresholds
		or neither.
		Note the driver will assume the last p events requested are
		to be enabled where p is however many it supports (which may
		vary depending on the exact set requested. So if you want to be
		sure you have set what you think you have, check the contents of
		these attributes after everything is configured. Drivers may
		have to buffer any parameters so that they are consistent when
		a given event type is enabled a future point (and not those for

Description:
		Description of the scan element data storage within the buffer
		and hence the form in which it is read from user-space.
		Form is [s|u]bits/storagebits[>>shift].  s or u specifies if
		signed (2's complement) or unsigned. bits is the number of bits
		of data and storagebits is the space (after padding) that it
		occupies in the buffer. shift if specified, is the shift that
		needs to be applied prior to masking out unused bits. Some
		devices put their data in the middle of the transferred elements
		with additional information on both sides.  Note that some
		devices will have additional information in the unused bits
		so to get a clean value, the bits value must be used to mask
		the buffer output value appropriately.  The storagebits value
		also specifies the data alignment.  So s48/64>>2 will be a
		signed 48 bit integer stored in a 64 bit location aligned to
		a a64 bit boundary. To obtain the clean value, shift right 2
		and apply a mask to zero the top 16 bits of the result.
		For other storage combinations this attribute will be extended
		appropriately.

Description:
		A single positive integer specifying the position of this
		scan element in the buffer. Note these are not dependent on
		what is enabled and may not be contiguous. Thus for user-space
		to establish the full layout these must be used in conjunction
		with all _en attributes to establish which channels are present,
		and the relevant _type attributes to establish the data storage
		format.
