When reading the position and velocity on the AD2S1210, there is also a
3rd byte following the two data bytes that contains the fault flag bits.
This patch adds support for reading this byte and generating events when
faults occur.
The faults are mapped to various channels and event type in order to
have a unique event for each fault.

The delta velocity is defined as a piece-wise integration of
acceleration data. The delta velocity represents the linear velocity
change between two consecutive measurements and it
is measured in m / s (meters per second).
In order to track the total linear velocity change during a desired
period of time, simply sum-up the delta velocity samples acquired
during that time.
IIO currently does not offer a suitable channel type for this
type of measurements hence this patch adds it.

There are devices (such as Murata IRS-D200 PIR proximity sensor) that
check the data signal with a running period. I.e. for a specified time,
they count the number of conditions that have occurred, and then signal
if that is more than a specified amount.
`IIO_EV_INFO_PERIOD` resets when the condition no longer is true and is
therefore not suitable for these devices. Add a new `iio_event_info`
`IIO_EV_INFO_RUNNING_PERIOD` that can be used as a running period. Also
add a new `IIO_EV_INFO_RUNNING_COUNT` that can be used to specify the
number of conditions that must occur during this running period.

A few IIC channel descriptions explained used units as:
data is in foo "that can be processed into an" [unit] value. The "can be
processed into" is quite broad statement as it does not really explain
what this processing means. This makes units pretty much useless.
After discussion with Jonathan, it seems the units for these channels
should also be well-defined as for all other channels. The processing
means the standard scale and offset application that is used throughout
the IIO. Let's make it more obvious by stating that the units are [unit]
after scale ane offset are applied.

Address an ABI gap for device where the offset of both lines in a
differential pair may be controlled so as to allow a wider range of
inputs, but without having any direct effect of the differential
measurement.
_offset cannot be used as to remain in line with existing usage,
userspace would be expected to apply it as (_raw + _offset) * _scale
whereas _zeropoint is not. i.e. If we were computing the differential
in software it would be.
((postive_raw + _zeropoint) - (negative_raw + zeropoint) + _offset) * _scale
= ((postive_raw - negative_raw) + _offset) * _scale
= (differential_raw + _offset) * _scale
Similarly calibbias is expected to tweak the measurement seen, not
the adjust the two lines of the differential pair.

It might be impossible to configure other attributes (e.g.: events, scale,
sampling rate) if they impact the currently active buffer capture session.
On ADXL367, writing to register before 0x2E requires the device to be
placed in standby mode, otherwise the changes might be effective for
only part of a measurement.
To ensure this requirement, the configuration attributes of the IIO
device try to claim direct mode before switching to standby mode.
During a buffer capture, direct mode cannot be claimed, and the
attribute write callback returns -EBUSY.

Commit 63cd35f34d ("iio: Documentation: update definitions for bufferY and scan_elements")
updated iio documentation in order to point to the newly
per-buffer API, as it is now possible to support multi buffers.
While the previous ABI will be kept forever, the best is
for applications to use the 5.11+ ABI. So, move the
legacy one ABI/obsolete.
This fixes an issue with scripts/get_abi.pl, that doesn't

This one is challenging as both the places this appears in specific drivers
are making 'unusual' uses of what looks like a simple output current
channel.
As a side note, this was particular bit of ABI occurs in other drivers
where the use is much more straight forward e.g. dac/ad5421
This patch attempts to make a best effort of adding it to the main docs but
retaining enough information. Both of these drivers probably need
specific documents being written to describe their unusual interfaces, but
those should be in the main documentation, not under Documentation/ABI.
That is a non trivial job so left for another time.

This device has the unusual characteristic that the calibbias values
have well defined units (more commonly they are tweaks to a DAC)
Unfortunately the previous approach of having more specific documentation
in sysfs-bus-iio-icm42600 results in warnings during the documentation
build and random ordering in the resulting documentation.
To avoid this, add a note to the main documentation on this special

Some 2-in-1 laptops / convertibles with 360° (yoga-style) hinges,
have 2 accelerometers, 1 in their base and 1 in their display.
In many cases the kernel can detect the location of each accelerometer
based on e.g. information from the ACPI tables.
It is important for userspace to know the location of the 2 accelerometers.
Rather then adding a new sysfs-attribute for this we can relay this
information to userspace by using standardized label strings for this.
This mirrors how this is done for proximity sensors.
This commit documents 2 new standardized label strings for this purpose:
"accel-base"
"accel-display"
Note the "base" and "display" suffixes were chosen to match the values
used for the systemd/udev hwdb.d/60-sensor.hwdb file's ACCEL_LOCATION
property.

First set of new device support, features and cleanups for IIO in the 5.11 cycle
Usual mixed bag of new drivers / device support + cleanups etc with the
addition of a fairly big set of yaml conversions.
Txt to yaml format conversions.
In some cases dropped separate binding and moved to trivial devices (drop).

If a label is defined for this channel add that to the channel specific
attributes. This is useful for userspace to be able to identify an
individual channel.

Since object temperature might be different than the sensor temperature
the infrared sensors should provide an interface to inject ambient
temperature. This was in past done via write to ambient temperature
interface (in_temp_ambient_raw), but I think most people did not know
about it. This solution introduces a new iio type of the CALIBAMBIENT
which is hopefully more descriptive and more explicit about the purpose
and capabilities of the sensors.

IIO_CONCENTRATION together with INFO_RAW specifier is used for reporting
raw concentrations of pollutants. Raw value should be meaningless
before being properly scaled. Because of that description shouldn't
mention raw value unit whatsoever.
Fix this by rephrasing existing description so it follows conventions
used throughout IIO ABI docs.
