Add '__adis_enable_irq()' implementation which is the unlocked
version of 'adis_enable_irq()'.
Call '__adis_enable_irq()' instead of 'adis_enable_irq()' from
'__adis_intial_startup()' to keep the expected unlocked functionality.
This fix is needed to remove a deadlock for all devices which are
using 'adis_initial_startup()'. The deadlock occurs because the
same mutex is acquired twice, without releasing it.
The mutex is acquired once inside 'adis_initial_startup()', before
calling '__adis_initial_startup()', and once inside
'adis_enable_irq()', which is called by '__adis_initial_startup()'.
The deadlock is removed by calling '__adis_enable_irq()', instead of
'adis_enable_irq()' from within '__adis_initial_startup()'.

Add the core driver for the BNO055 IMU from Bosch. This IMU can be
connected via both serial and I2C busses; separate patches will add support
for them.
The driver supports "AMG" (Accelerometer, Magnetometer, Gyroscope) mode,
that provides raw data from the said internal sensors, and a couple of
"fusion" modes (i.e. the IMU also does calculations in order to provide
euler angles, quaternions, linear acceleration and gravity measurements).
In fusion modes the AMG data is still available (with some calibration
refinements done by the IMU), but certain settings such as low pass filters
cut-off frequency and sensors' ranges are fixed, while in AMG mode they can
be customized; this is why AMG mode can still be interesting.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

safety alignment issue identified due to improved understanding of

Device support

Cleanup and minor fixes:
Treewide changes
- Cleanup of error handling in remove functions in many drivers.
- Update dt-binding maintainers for a number of ADI bindings.
- Several sets of conversion of drivers from device tree specific to
generic device properties. Includes fixing up various related

- Drop include of of.h from iio.h and fix up drivers that need to include

- More moves of clusters of drivers into appropriate IIO_XXX namespaces.
- Tree wide fix of a long running bug around DMA safety requirements.
IIO was using __cacheline_aligned to pad iio_priv() structures. This
worked for a long time by coincidence, but correct alignment is
ARCH_KMALLOC_MINALIGN. As there is activity around this area, introduce
an IIO local IIO_DMA_MINALIGN to allow for changing it in one place rather

The 0 value used for INV_CHIP_ICM42600 was not working since the
match in i2c/spi was checking against NULL value.
To keep this check, add a first INV_CHIP_INVALID 0 value as safe

Instead of returning an error if the watermark value is too high, which
the core will silently ignore anyway, limit the value to the hardware
FIFO size; a lower-than-requested value is still better than using the
default, which is usually 1.

The extended clocks are optional and may not be present for some

the clock is provided but some error happens during its getting,
that error handling should be done properly.
Use devm_clk_get_optional() API and report possible errors using
dev_err_probe() to handle properly -EPROBE_DEFER error.

This register write to REG_INTF_CONFIG6 enables a spike filter that
is impacting the line and can prevent the I2C ACK to be seen by the

Among all the users of the kfifo buffers, no one uses the
INDIO_BUFFER_HARDWARE mode. So let's take this as a general rule and
simplify a little bit the internals - overall the documentation - by
eliminating unused specific cases. Use the INDIO_BUFFER_SOFTWARE mode by
default with kfifo buffers, which will basically mimic what all the "non
direct" modes do.

The difference between the ICM-20608-D and the other ICM-20608
variants is the addition of a DMP (Digital Motion Processor) core.
This difference is deemed substantial enough to change the WHOAMI
register value.
Since this driver doesn't currently acknowledge the exisence of
something like a DMP core, simply copy ICM-20608 except for the
aforementioned WHOAMI register.

This cycle we had quite a few series that applied similar changes
to lots of drivers. To keep this description manageable I have
called those out in their own section rather than per driver.
Particularly pleased to see the long running AFE precision series
going in this cycle.
Series includes some late breaking fixes.
New device support
* adi,ada4250 amplifier
- New driver and dt bindings for this programmable gain amplifier.
* adi,admv1014 microwave down-converter
- New driver, dt bindings and some device specific ABI that
may be generalized as more drivers for devices similar to this
are added.
* adi,admv4420 K Band down-converter.
- New driver and dt bindings.
* adi,adxl367 accelerometer driver.
- New driver, dt-bindings + some new IIO ABI definitions to support
reference magnitude events where an estimate of the acceleration
due to gravity has been removed.
- A few fixes as follow up patches.
* adi,ltc2688 DAC with toggle and dither modes.
- New driver and bindings. Includes some new driver specific (for now)
ABI for handling toggle mode and the addition of a dither waveform to
the DAC output.
* AFE (analog front end) add support for additional types of analog device
in front of an ADC.
- RTD temperature sensors with dt bindings.
- Temperature transducers wit dt bindings.
- Related cleanup and features listed in other sections below.
* maxim,ds3502 potentiometer.
- Add support to ds1803 driver which required significant rework.
* mediatek,mt2701-auxadc driver
- Add mediatek,mt8186-auxadc - id table and chip specific info only.
* semtech,sx9324, semtech,ax9360
- Substantial refactoring of sx9310 to extract core logic for reuse
into a separate module
- New driver using this supporting sx9324 proximity sensors.
- New driver using this supporting sx9360 proximity sensors.
* silan,sc7a20
- Compatible with the st,lis2dh (or nearly anyway) so add ID and
chip specific info to enable support. Also silan vendor ID added
for dt-bindings.
Staging graduation
* adi,ad7280a monitoring ADC for stacked lithium-ion batteries in
electric cars and similar.
- Substantial rework of driver required to bring inline with current
IIO best practice. An unusual device in IIO so some interesting features
we may see more of in future.
Multiple driver/core cleanup
- Use sysfs_emit() in simple locations where there is no path to change
to various core created attributes.
- Trivial white space fixes around inconsistency between space after { and
before } in id tables.
- Introduce new handling for fractional types to avoid repeated similar
implementations. Use this in 3 drivers. Note this is also targeted
at future use in the AFE driver and was motivated by discussions
around the precision related work on that driver.
- of related header cleanups - drop of*.h and add mod_devicetable.h as
appropriate.
- Move a number of symbol exports into IIO_* namespaces. Two categories,
1) Library used by multiple drivers e.g. st_sensors
2) Core driver module exporting functions used by bus specific modules.
A few related cleanups in this set.
- Switch from CONFIG_PM_* guards to new DEFINE_SIMPLE_DEV_PM_OPS() and
similar to simplify drivers and take advantage of these new macros
allowing the compiler to do the job or removing unused code without
the need for __maybe_unused markings. Conversion of other drivers to
these new macros ongoing.
Features
* adi,adf4350
- Switch from of specific to generic device properties enabling use with
other firmware types.
