2e3ae10c35 iio: adc: ad7191: add AD7191 
AD7191 is a pin-programmable, ultra-low noise 24-bit sigma-delta ADC
designed for precision bridge sensor measurements. It features two
differential analog input channels, selectable output rates,
programmable gain, internal temperature sensor and simultaneous
50Hz/60Hz rejection.

21ce1ce043 staging: iio: accel: adis16240: Drop driver for this impact sensor 
Whilst an interesting part, no one has done significant work on this
driver since 2019.  The recent changes are all as a result of adis library
improvements having to incorporate this device.

https://www.analog.com/en/products/adis16240.html now lists this part
as obsolete so the chances of anyone working on it are likely to be greatly
reduced.

So drop it.  We can always bring it back if anyone does have interest in
this device and is willing to invest the time to make it suitable for a
staging graduation.  How to handle the hardware triggered short bursts
of capture has never been resolved and is a somewhat challenging ABI design
problem.

62c6b4f1c7 iio: accel: adxl345: reorganize irq handler 
Reorganize the IRQ handler. Move the overrun handling to the bottom.
Overrun leads to reset the interrupt register. This also happens at
evaluation of a particular interrupt event. First evaluate an event
if possible, then fall back to overrun handling. Additionally simplify
fetching the interrupt status function.

Both is in preparation to build interrupt handling up for the handling
of different detected events, implemented in follow up patches.

9b4b9791dd Documentation: iio: Add ADC documentation 
ADC inputs can be classified into a few different types according to how
they measure the input signal, how restrained the signal is, and number of
input pins. Even though datasheets tend to provide many details about their
inputs and measurement procedures, it may not always be clear how to model
those inputs into IIO channels.

For example, some differential ADCs can have their inputs configured into
pseudo-differential channels. In that configuration, only one input
connects to the signal of interest as opposed to using two inputs of a
differential input configuration. Datasheets sometimes also refer to
pseudo-differential inputs as single-ended inputs even though they have
distinct physical configuration and measurement procedure.

Document consolidated ADC input types and how they are usually described
and supported in device tree and IIO, respectively.

cafeb8a997 iio: adc: ad4695: fix out of bounds array access 
Fix some out of bounds array access of st->channels_cfg in the ad4695
driver. This array only has elements for voltage channels, but it was
also being accessed for the temperature channel in a few cases causing
reading past the end of the array.

In some cases, this was harmless because the value was read but not
used. However, the in_temp_sampling_frequency attribute shares code
with the in_voltageY_sampling_frequency attributes and was trying to
read the oversampling ratio from the st->channels_cfg array. This
resulted in a garbage value being used in the calculation and the
resulting in_temp_sampling_frequency value was incorrect.

To fix, make sure we always check that we are dealing with a voltage
channel before accessing the st->channels_cfg array and use an
oversampling ratio of 1 for the temperature channel (multiplicative
identity value) since that channel doesn't support oversampling.

035b498921 iio: backend: make sure to NULL terminate stack buffer 
Make sure to NULL terminate the buffer in
iio_backend_debugfs_write_reg() before passing it to sscanf(). It is a
stack variable so we should not assume it will 0 initialized.

1a21a9842e iio: adc: Switch to sparse friendly iio_device_claim/release_direct() 
Single patch for all the relatively simple cases.

These new functions allow sparse to find failures to release
direct mode reducing chances of bugs over the claim_direct_mode()
functions that are deprecated.

386c1d6e41 iio: adc: max11410: Factor out writing of sampling frequency to simplify errro paths. 
Introduce __max11410_write_samp_freq() helper and use guard() to avoid
need for manual unlock of the mutex. This allows direct returns and
simplifies the resulting error handling.

These new functions allow sparse to find failures to release

This is a complex function with a lot more than the release of direct
mode to unwind on error. As such no attempt made to factor out
the inner code.
