strtobool() is deprecated and just a wrapper around kstrtobool().Replace
it with kstrtobool() so the deprecated function can be removed eventually.

Pull spi updates from Mark Brown:
"The overwhelming bulk of this pull request is a change from Uwe
Kleine-König which changes the return type of the remove() function to
void as part of some wider work he's doing to do this for all bus
types, causing updates to most SPI device drivers. The branch with
that on has been cross merged with a couple of other trees which added
new SPI drivers this cycle, I'm not expecting any build issues
resulting from the change.
Otherwise it's been a relatively quiet release with some new device
support, a few minor features and the welcome completion of the
conversion of the subsystem to use GPIO descriptors rather than
numbers:
- Change return type of remove() to void.
- Completion of the conversion of SPI controller drivers to use GPIO
descriptors rather than numbers.
- Quite a few DT schema conversions.
- Support for multiple SPI devices on a bus in ACPI systems.
- Big overhaul of the PXA2xx SPI driver.
- Support for AMD AMDI0062, Intel Raptor Lake, Mediatek MT7986 and
MT8186, nVidia Tegra210 and Tegra234, Renesas RZ/V2L, Tesla FSD and

First set of new device support, fixes, cleanups and features for IIO in 5.18
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.
* adi,adx345
- Switch from of specific to generic device properties.
- Add ACPI ID ADS0345
- Related driver cleanup.
* adi,hmc425a
- Switch from of specific to generic device properties.
* afe analog rescaler driver
- Wider range of types supported for scale.
- Support offset.
- Kunit tests.
* atlas,ezo-sensor
- Convert from of to device properties.
* fsl,mma8452
- Support mount matrix.
* infineon,dps310:
- Add ACPI ID IFX3100.
* invensense,mpu6050
- Convert to generic device properties.
* maxim,ds1803
- Add out_raw_available before supporting more devices.
- Convert from of specific to device properties.
* samsung,ssp_sensors
- Convert from of specific to device properties.
* st,stm32-timer trigger
- Convert from of specific to device properties.
* ti,hdc101x

* ti,tsc2046:
- Add read_raw support to enable use of iio_hwmon and similar.
Fixes / cleanup.
* mailmap
- Update for Cai Huoqing
* MAINTAINERS
- Fix Analog Devices related links.
- Add entry for ADRF6780
- Add entry for ADMV1013
- Add entry for AD7293
- Add entry for ADMV8818
- Update files listed for adis-lib
* iio core:
- Fix wrong comment about current_mode being something a driver should
ever access.
- Use struct_size() rather than open coding in industrialio-hw-consumer
* adi,axl355
- Use units.h definitions instead of local versions.
* adi,adis-lib
- Simplify *updated_bits() macro
- Whitespace cleanup.
* afe - Note many of these fixes only apply to particular configurations
so the problems have probably not been seen in the wild, but will be
visible with new usecases enabled this cycle.
- Fix application of consumer scale for IIO_VAL_INT.
- Apply a scale of 1 when no scale is provided.
- Make best effort to establish a valid offset value for fractional
cases.
- Use s64 for scale calculations where parameters may be signed.
- Tidy up include order.
- Improve accuracy for small fractional sales
- Reduce risk of integer overflow.
* ams,as3935
- Use devm_delayed_work_autocancel() to replace open coded equivalent.
* aspeed,adc
- Fix wrong use of divider flag.
* atmel,sama5d2-adc
- Relax atmel,trigger-edge-type to optional.
- Drop Ludovic Desroches from listed maintainers of the dt-binding
inline with previous MAINTAINERS entry update.
* fsl,mma8452
- Fix probing when i2c_device_id used.
- dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev.
Use dev_to_iio_dev() instead. Note the original path in here
worked more by luck than design.
* invensense,mpu6050
- Drop ACPI_PTR() protection to avoid an unused warning.
- Use fact ACPI_COMPANION() returns null when ACPI_HANDLE() does to
simplify handling.
* motorola,cpcap-adc

board. Default is still to enable the bus specific module if
appropriate bus is supported.
* st,lsm6dsx
- dev_get_drvdata() on the iio_dev->dev, no longer returns iio_dev.
Use dev_to_iio_dev() instead.
* ti,palmas-gpadc
- Split the interrupt fields in the dt-binding example
* ti,tsc2046
- Rework state machine to improve readability after recent debugging of
an issue fixed elsewhere.
- Add a sanity check to avoid very large memory allocations if a crazy
delay is specified.
* ti,twl6030
- Add error handling if devm_request_threaded_irq() fails.
* xilinx,ams
- Use devm_delayed_work_autocancel() instead of open coding equivalent.
- Fix missing required clock entry in dt-binding.
- Fix miss counting of channels resulting in ps channels not
being enabled.
- Fix incorrect values written to sequencer registers.
- Fix sequence for single channel reading.

The value returned by an spi 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.

As part of the general cleanup of indio_dev->mlock, this change replaces
it with a local lock.
The lock protect the state of the device from potential concurrent writes.
The device is configured via a sequence of SPI writes, and this lock is
meant to prevent the start of another sequence before another one has
finished.
This is part of a bigger cleanup.

This patch applies the semantic patch:
@@
expression I, P, SP;
@@
I = devm_iio_device_alloc(P, SP);
...
- I->dev.parent = P;
It updates 302 files and does 307 deletions.
This semantic patch also removes some comments like
'/* Establish that the iio_dev is a child of the i2c device */'
But this is is only done in case where the block is left empty.
The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.
In other cases, the block covered by ... may be just too big to be covered
by the semantic patch.
However, this looks pretty good as well, as it does cover a big bulk of the
drivers that should remove the parent assignment.

Second set of IIO device support, features, cleanups and minor fixes for 5.3.
A few bits for the counters subsystem mixed in here as well.
There are some late breaking fixes as well, which aren't so urgent
they can't wait for the merge window.
New Device Support
* adf4371
- New driver + bindings.
- Support the adf4372 PLL. Mostly ID and bindings.
* ad8366 (note includes rework of driver needed to allow support for these).
- Support the ADL5240 variable gain amplifier (VGA).
- Support the ADA4961 digital gain amplifier (DGA).
* dps310
- New driver, in several parts from different authors for this temp
and pressure sensor.
- Includes errata workaround for a temperature reading issue.
* stk3310
- Support the stk3335, mostly ID.
Features and cleanups
* core
- drop error handling on debugfs registration.
- harden by making sure we don't overrun iio_chan_info_postfix.
* docs
- convert remaining docs to rst. At somepoint we'll fit these few
into the main IIO docs.
- improve sampling_frequency_available docs but explaining the
range form.
* ad_sigma_delta
- Drop a pointless goto.
* ad2s1210
- Drop pointless platform data null check seeing as we don't actually
use platform data anymore.
* ad7124
- Relax limitation on channel numbers to allow pseudo different channels.
- Support control of whether the input is buffered via DT.
- Use dynamic allocation for channel configuration to make it easier
to support new devices.
- YAML binding conversion.
* ad7150
- Comment tidy up.
- Consistent and simple if (ret) handling of i2c errors.
- FIELD_GET and GENMASK.
- Ternary rather than !!(condition) for readability.
- Use macros to avoid repetition of channel definitions.
* ad7606
- Add software channel config (rather that pin controlled)

Another feature of the ADF4371/ADF4372 is that the supply current to the
RF8P and RF8N output stage can shut down until the ADF4371 achieves lock
as measured by the digital lock detect circuitry. The mute to lock
detect bit (MUTE_LD) in REG25 enables this function.

The ADF4372 is part of the same family with ADF4371, the main difference
is that it has only 3 channels instead of 4, as the frequency quadrupler
is missing. As a result, the ADF4372 allows frequencies from 62.5 MHz to
16 GHz to be generated.

The ADF4371 is a frequency synthesizer with an integrated voltage
controlled oscillator (VCO) for phase-locked loops (PLLs). The ADF4371
has an integrated VCO with a fundamental output frequency ranging from
4000 MHz to 8000 MHz. In addition, the VCO frequency is connected to
divide by 1, 2, 4, 8, 16, 32, or 64 circuits that allows the user to
generate radio frequency (RF) output frequencies as low as 62.5 MHz at
RF8x. A frequency multiplier at RF16x generates from 8 GHz to 16 GHz. A
frequency quadrupler generates frequencies from 16 GHz to 32 GHz at RF32x.
RFAUX8x duplicates the frequency range of RF8x or permits direct access to
the VCO output.
The driver takes the reference input frequency from the device tree and
uses it to calculate and maximize the PFD frequency (frequency of the phase
frequency detector). The PFD frequency is further used to calculate the
timeouts: synthesizer lock, VCO band selection, automatic level
calibration (ALC) and PLL settling time.
This initial driver exposes the attributes for setting the frequency and
enabling/disabling the different adf4371 channels.

A sysfs write callback function needs to either return the number of
consumed characters or an error.
The ad952x_store() function currently returns 0 if the input value was "0",
this will signal that no characters have been consumed and the function
will be called repeatedly in a loop indefinitely. Fix this by returning
number of supplied characters to indicate that the whole input string has
been consumed.

This is also part of a long term effort to make the use of mlock opaque and

This lock is required for accessing device registers. The device may be
accessed by multiple processes at the same time, and this can result in

finished writing.

The SPI core always reports the MODALIAS uevent as "spi:<modalias>"
regardless of the mechanism that was used to register the device
(i.e: OF or board code) and the table that is used later to match
the driver with the device (i.e: SPI id table or OF match table).
So drivers needs to export the SPI id table and this be built into
the module or udev won't have the necessary information to autoload
the needed driver module when the device is added.
