Letting the compiler remove these functions when the kernel is built
without CONFIG_PM support is simpler and less error prone than the
use of #ifdef based config guards.
Removing instances of this approach from IIO also stops them being
copied into new drivers.

The mentioned change effectively broke the ODR startup timeouts
settungs for KX023-1025 case. Let's revert it for now and see
how we can handle it with the better approach after switching
the driver to use data structure instead of enum.

Resolved movement of asm/unaligned.h to linux/unaligned.h
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.
Convert all platform drivers below drivers/iio/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.
While touching these files, make indention of the struct initializer
consistent in several files.

In the current implementation, the local variable field_value is used
without prior initialization, which may lead to reading uninitialized
memory. Specifically, in the macro set_mask_bits, the initial
(potentially uninitialized) value of the buffer is copied into old__,
and a mask is applied to calculate new__. A similar issue was resolved in
commit 6ee2a7058f ("iio: accel: bma400: Fix smatch warning based on use
of unintialized value.").

The ADXL380/ADXL382 is a low noise density, low power, 3-axis
accelerometer with selectable measurement ranges. The ADXL380 supports
the +/-4 g, +/-8 g, and +/-16 g ranges, and the ADXL382 supports
+/-15 g, +/-30 g and +/-60 g ranges.
The ADXL380/ADXL382 offers industry leading noise, enabling precision
applications with minimal calibration. The low noise, and low power
ADXL380/ADXL382 enables accurate measurement in an environment with
high vibration, heart sounds and audio.
In addition to its low power consumption, the ADXL380/ADXL382 has many
features to enable true system level performance. These include a
built-in micropower temperature sensor, single / double / triple tap
detection and a state machine to prevent a false triggering. In
addition, the ADXL380/ADXL382 has provisions for external control of
the sampling time and/or an external clock.

The big one here is we finally have Paul Cercueil's (and others)
DMA buffer support for IIO devices enabling high speed zero
copy transfer of data to and from sensors supported by IIO (and for
example USB). This should aid with upstream support of a range of
higher performance ADCs and DACs.
Two merges from other trees
- spi/spi_devm_optimize used for simplification in ad7944.
- dmaengine/topic_dma_vec to enable the DMABUF series.
One feature with impact outside IIO.
- Richer set of dev_err_probe() like helpers to cover ERR_PTR() cases.
New device support
==================
adi,ad7173
- Add support for AD4111, AD4112, AD4114, AD4115 and ADC4116 pseudo
differential ADCs. Major driver rework was needed to enabled these.
adi,ad7944
- Use devm_spi_optimize_message() to avoid a local devm cleanup
callback. This is the example case from the patch set, others will
follow.
mediatek,mt6359-auxadc
- New driver for this ADC IP found in MT6357, MT6358 and MT6359 PMICs.
st,accel
- Add support for the LIS2DS12 accelerometer
ti,ads1119
- New driver for this 16 bit 2-differential or 4-single ended channel
ADC.
Features
========
dt-bindings
- Introduce new common-mode-channel property to help handle pseudo
differential ADCs where we have something that looks like one side
of differential input, but which is only suited for use with a
slow moving reference.
adi,adf4350
- Support use as a clock provider.
iio-hmwon
- Support reading of labels from IIO devices by their consumers and
use this in the hwmon bridge.
Cleanup and minor fixes
=======================
Treewide
- Use regmap_clear_bits() / regmap_set_bits() to simplify open coded
equivalents.
- Use devm_regulator_get_enable_read_voltage() to replace equivalent
opencoded boilerplate. In some cases enabled complete conversion to
devm handling and removal of explicit remove() callbacks.
- Introduce dev_err_ptr_probe() and other variants and make use of
of them in a couple of examples driver cleanups. Will find use in
many more drivers soon.
adi,ad7192
- Introduce local struct device *dev and use dev_err_probe() to give
more readable code.
adi,adi-axi-adc/dac
- Improved consistency of messages using dev_err_probe()
adi,adis
- Split the trigger handling into cases that needed paging and those that
don't resulting in more readable code.
- Use cleanup.h to simplify error paths via scoped cleanup.
- Add adis specific lock helpers and make use of them in a number of drivers.
adi,ad7192
- Update maintainer (Alisa-Dariana Roman)
adi,ad7606
- dt-binding cleanup.
avago,apds9306
- Add a maintainer entry (Subhajit Ghosh)
linear,ltc2309
- Fix a wrong endian type.
st,stm32-dfsdm
- Fix a missing port property in the dt-binding.
st,sensors
- Relax whoami match failure to a warning print rather than probe failure.
This enables fallback compatibles to existing parts from those that don't
necessarily even exit yet.

IIO: 2nd set of new device support, features and cleanup for 6.11
The big one here is we finally have Paul Cercueil's (and others)
DMA buffer support for IIO devices enabling high speed zero
copy transfer of data to and from sensors supported by IIO (and for
example USB). This should aid with upstream support of a range of
higher performance ADCs and DACs.
Two merges from other trees
- spi/spi_devm_optimize used for simplification in ad7944.
- dmaengine/topic_dma_vec to enable the DMABUF series.
One feature with impact outside IIO.
- Richer set of dev_err_probe() like helpers to cover ERR_PTR() cases.
New device support
==================
adi,ad7173
- Add support for AD4111, AD4112, AD4114, AD4115 and ADC4116 pseudo
differential ADCs. Major driver rework was needed to enabled these.
adi,ad7944
- Use devm_spi_optimize_message() to avoid a local devm cleanup
callback. This is the example case from the patch set, others will
follow.
mediatek,mt6359-auxadc
- New driver for this ADC IP found in MT6357, MT6358 and MT6359 PMICs.
st,accel
- Add support for the LIS2DS12 accelerometer
ti,ads1119
- New driver for this 16 bit 2-differential or 4-single ended channel
ADC.
Features
========
dt-bindings
- Introduce new common-mode-channel property to help handle pseudo
differential ADCs where we have something that looks like one side
of differential input, but which is only suited for use with a
slow moving reference.
adi,adf4350
- Support use as a clock provider.
iio-hmwon
- Support reading of labels from IIO devices by their consumers and
use this in the hwmon bridge.
Cleanup and minor fixes
=======================
Treewide
- Use regmap_clear_bits() / regmap_set_bits() to simplify open coded
equivalents.
- Use devm_regulator_get_enable_read_voltage() to replace equivalent
opencoded boilerplate. In some cases enabled complete conversion to
devm handling and removal of explicit remove() callbacks.
- Introduce dev_err_ptr_probe() and other variants and make use of
of them in a couple of examples driver cleanups. Will find use in
many more drivers soon.
adi,ad7192
- Introduce local struct device *dev and use dev_err_probe() to give
more readable code.
adi,adi-axi-adc/dac
- Improved consistency of messages using dev_err_probe()
adi,adis
- Split the trigger handling into cases that needed paging and those that
don't resulting in more readable code.
- Use cleanup.h to simplify error paths via scoped cleanup.
- Add adis specific lock helpers and make use of them in a number of drivers.
adi,ad7192
- Update maintainer (Alisa-Dariana Roman)
adi,ad7606
- dt-binding cleanup.
avago,apds9306
- Add a maintainer entry (Subhajit Ghosh)
linear,ltc2309
- Fix a wrong endian type.
st,stm32-dfsdm
- Fix a missing port property in the dt-binding.
st,sensors
- Relax whoami match failure to a warning print rather than probe failure.
This enables fallback compatibles to existing parts from those that don't
necessarily even exit yet.

These drivers don't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.
While add it, also remove commas after the sentinel entries.

Some devices use the semi-standard ACPI "ROTM" method to store
the accelerometers orientation matrix.
Add support for this using the new iio_read_acpi_mount_matrix() helper, if
the helper fails to read the matrix fall back to iio_read_mount_matrix()
which will try to get it from device-properties (devicetree) and if
that fails it will fill the matrix with the identity matrix.

There are 2 issues with interrupt handling in the mxc4005 driver:
1. mxc4005_set_trigger_state() writes MXC4005_REG_INT_MASK1_BIT_DRDYE
(0x01) to INT_MASK1 to enable the interrupt, but to disable the interrupt
it writes ~MXC4005_REG_INT_MASK1_BIT_DRDYE which is 0xfe, so it enables
all other interrupt sources in the INT_SRC1 register. On the MXC4005 this
is not an issue because only bit 0 of the register is used. On the MXC6655
OTOH this is a problem since bit7 is used as TC (Temperature Compensation)
disable bit and writing 1 to this disables Temperature Compensation which
should only be done when running self-tests on the chip.
Write 0 instead of ~MXC4005_REG_INT_MASK1_BIT_DRDYE to disable
the interrupts to fix this.
2. The datasheets for the MXC4005 / MXC6655 do not state what the reset
value for the INT_MASK0 and INT_MASK1 registers is and since these are
write only we also cannot learn this from the hw. Presumably the reset
value for both is all 0, which means all interrupts disabled.
Explicitly set both registers to 0 from mxc4005_chip_init() to ensure
both masks are actually set to 0.

IIO Backend support
===================
New approach from Nuno Sa to the problem of reuse of drivers with
IIO devices that are actually the combination of a highspeed chip
and an FPGA core handling the data capture and flows. It will hopefully
also apply to some other split designs. The ad9467 and axi-adi drivers
are converted over to this framework.
New device support
==================
adi,admfm2000
- New driver for this dual microwave down converter.
ams,as73211
- Add support for as7331 UV sensor.
richtek,rtq6056
- Add support for related parts RTQ6053 and RTQ6059
st,lsm6dsx
- Add ASM330LHHXG1 accelerometer and gyro support (mainly IDs)
ti,ads1298
- New driver for this medical ADC.
Features
========
tests
- Unit tests for the gain-time-scale helper library.
bosch,bmi088
- I2C support.
bosh,bmi160
- Add 10EC5280 ACPI ID. Used in a number of devices that won't get fixed.
The ID is actually a PCI ID belonging to realtech. No response was received
to earlier attempts to notify them of this.
The manufacturers of some devices have replied to say they will not fix
this incorrect ID. Add the ID and hope it isn't a problem.
bosch,bmi323
- Add BOSC0200 ACPI ID. Note this is a duplicate of one in the bmc150
driver (it appears these parts share a windows driver).
Both drivers perform an ID check that is safe on the other part before
successfully probing.
hid-sensors-als
- Add color temperature and chromaticity support. Note this is a replacement
for the series reverted in 6.8 that correctly handles all the potential
channel combinations.
honeywell,hsc030pa
- Triggered buffer support (after driver cleanup).
honeywell,mprls00025pa
- Improved error handling.
- New DT binding to allow use of part number triplet as provided in data sheet
to specify equivalent of most of the binding more efficiently.
- SPI support.
memsic,mxc4005
- ACPI ID MDA6655 as seen in the Chuwi Minibook X 2023
ti,hdc3020
- Add threshold event support (after some driver cleanup)
veml,vcnl4000

Merge tag 'iio-for-6.9a' of http://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next

IIO: 1st set of new device support, features and cleanup for 6.9
IIO Backend support
===================
New approach from Nuno Sa to the problem of reuse of drivers with
IIO devices that are actually the combination of a highspeed chip
and an FPGA core handling the data capture and flows. It will hopefully
also apply to some other split designs. The ad9467 and axi-adi drivers
are converted over to this framework.
New device support
==================
adi,admfm2000
- New driver for this dual microwave down converter.
ams,as73211
- Add support for as7331 UV sensor.
richtek,rtq6056
- Add support for related parts RTQ6053 and RTQ6059
st,lsm6dsx
- Add ASM330LHHXG1 accelerometer and gyro support (mainly IDs)
ti,ads1298
- New driver for this medical ADC.
Features
========
tests
- Unit tests for the gain-time-scale helper library.
bosch,bmi088
- I2C support.
bosh,bmi160
- Add 10EC5280 ACPI ID. Used in a number of devices that won't get fixed.
The ID is actually a PCI ID belonging to realtech. No response was received
to earlier attempts to notify them of this.
The manufacturers of some devices have replied to say they will not fix
this incorrect ID. Add the ID and hope it isn't a problem.
bosch,bmi323
- Add BOSC0200 ACPI ID. Note this is a duplicate of one in the bmc150
driver (it appears these parts share a windows driver).
Both drivers perform an ID check that is safe on the other part before
successfully probing.
hid-sensors-als
- Add color temperature and chromaticity support. Note this is a replacement
for the series reverted in 6.8 that correctly handles all the potential
channel combinations.
honeywell,hsc030pa
- Triggered buffer support (after driver cleanup).
honeywell,mprls00025pa
- Improved error handling.
- New DT binding to allow use of part number triplet as provided in data sheet
to specify equivalent of most of the binding more efficiently.
- SPI support.
memsic,mxc4005
- ACPI ID MDA6655 as seen in the Chuwi Minibook X 2023
ti,hdc3020
- Add threshold event support (after some driver cleanup)
veml,vcnl4000
- Switch to high resolution proximity measurement.

The complexity of config guards needed for ACPI_PTR() is not worthwhile
for the small amount of saved data. This example was doing it correctly
but I am proposing dropping this so as to reduce chance of cut and paste
where it is done wrong. Also drop now unneeded linux/acpi.h include.

In general the complexity of avoiding maybe unused variable warnings is
not worth dealing with for the small amount of data saved. In thie
case, the i2c driver does include some other code under a CONFIG_ACPI
guard but remove the ACPI_PTR() usage anyway to bring keep it inline
with the spi driver.
Drop include of linux/acpi.h in the spi driver that doesn't need
it as struct acpi_device_id is defined in mod_devicetable.h which
is already included.

This avoids a build warning due to the use of ACPI_PTR().
Given the driver already has APCI specific code under CONFIG_ACPI move

have the complexity of CONFIG_ACPI.

In general using ACPI_PTR() leads to more fragile code for a very
minor saving in storage in the case of !CONFIG_ACPI so in IIO we
prefer not to use it if the only ACPI specific code is the acpi_device_id
table.
In this case will also suppress a unused variable warning.

The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().
Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

The fwnode_irq_get_byname() was returning 0 at device-tree mapping
error. If this occurred, the KX022A driver did abort the probe but
errorneously directly returned the return value from
fwnode_irq_get_byname() from probe. In case of a device-tree mapping
error this indicated success.
The fwnode_irq_get_byname() has since been fixed to not return zero on
error so the check for fwnode_irq_get_byname() can be relaxed to only
treat negative values as errors. This will also do decent fix even when
backported to branches where fwnode_irq_get_byname() can still return
zero on error because KX022A probe should later fail at IRQ requesting
and a prober error handling should follow.
Relax the return value check for fwnode_irq_get_byname() to only treat
negative values as errors.

Devices which may take a while to initialize during probe and which have
no strong reason to probe synchronously can request asynchronous probing
as default probe strategy. This can speed-up start times on some
platforms.
The KX022A gets probe delayed for at least two reasons. It enables the
supply regulator, (which is likely to have ramp-up delay if it was
disabled) and additionally it delays while the sensor itself is
initializing.
Changing to asynchronous probing may cause problems. Some of which are
discussed in:
https://lore.kernel.org/all/06db017f-e985-4434-8d1d-02ca2100cca0@sirena.org.uk/

When apply_acpi_orientation() fails, st_accel_common_probe() will fall back
to iio_read_mount_matrix(), which checks for a mount-matrix device property
and if that is not set falls back to the identity matrix.
But when a sensor has no ACPI companion fwnode, or when the ACPI fwnode
does not have a "_ONT" method apply_acpi_orientation() was returning 0,
causing iio_read_mount_matrix() to never get called resulting in an
invalid mount_matrix:
[root@fedora ~]# cat /sys/bus/iio/devices/iio\:device0/mount_matrix
(null), (null), (null); (null), (null), (null); (null), (null), (null)
Fix this by making apply_acpi_orientation() always return an error when
it did not set the mount_matrix.

Jonathan writes:
1st set of IIO new device support, features and cleanups for the 6.4 cycle.
New device support
* bosch,bmp280
- Add support for BMP580 - includes significant refactoring and general
driver cleanup + support for non-volatile memory for trimming and config
parameters.
* rohm BU27034
- New driver for this 3 channel ambient light sensor.
- New support library for devices where both integration time and
amplifier gain are configurable. In these cases a scale change
may require changing bother underlying values. This library module
provides code to help with this.
* st,accel
- Add support for IIS328DQ (ID only as compatible wtih LIS331DL)
* st,lsm6dsx
- Add support for ASM330LHB automotive MEMS sensor.
* ti,ads1100, ads1000
- New driver for these 16 bit ADCs.
* ti,tmp117
- Add support for older tmp116 device. Includes some general driver cleanup.
Staging driver drops
* adi,ade7854
- Driver was a very long way from compliant with IIO infrastructure and ABI.
If anyone wants a non staging version of this driver they are better off
starting from scratch. Hence drop it and the associated meter.h header.
Features
* adi,ad7441r
- Add DT binding to set sink current for digital input.
* semtech,sx9324,9360
- Support older register mapping from firmware designed for windows.
Core improvements.
* Move iio_trigger_poll() docs to next to the implementation and add a note
on expected caller context.
* Rename iio_trigger_poll_chained() to iio_trigger_poll_nested() so
as to use more standard / common terminology.
* Improve main ABI docs references to offset and scale for raw values by
making them consistent and clear.
Cleanups and minor fixes:
* adi,ad5592r
- Add GPIO names - useful for debug.
* adi,ad7441r
- Fix current input, loop powered mode configuration setup.
* adi,adis16475
- Fix wrong commented value for minimum advised lower rate.
* adi,admv1013
- Use devm_clk_get_enabled() to reduce boilerplate.
* adi,ads1210
- Fix wrong bits for writing config register (late fix and has
been broken a long time so not rushed upstream)
* amlogic,meson-saradc
- Improve cleanup in error handling if BL30 handshake fails.
* apex-embedded,stx104
- Migrate to regmap and use regmap_read_poll_timeout() to neatly handle
retries.
- Add local mutex to close various races.
- Use define U16_MAX rather than value for limit.
- Improve code readability with minor reorganization.
* atmel,ad91-sama5d2
- Drop trivial dead code.
* kionix,kx022a
- Drop unused structure element.
* linear,ltc2983
- Reorganize bindings doc to enable unevaluatedProperties to be set
in one place for all child nodes.
- Make binding for adi,custom-thermocouple accept signed values.
* maxim,max44000
- Add OF Device matching (of_match_table was not correctly set).
* maxim,max5522
- Missing static
* measurement-computing,cio-dac
- Fix wrong part name in comments.
- Migrate to regmap.
- Improve includes by replacing bitops.h with more direct bits.h
* qcom,pm8xxx-xoadc
- Remove a check that can never fail.
* renesas,rcar-gyroadc
- DT binding documentation improvements.
- Tidy up an unused warning with __maybe_unused.
* semtech,sx_common
- Drop docs for a structure element that doesn't exist.
* semtech,sx9500
- Drop ACPI_PTR() and of_match_ptr() protections that just complicate
the code / block some firmware registration types that would otherwise
work.
* sensiron,sps30
- Comment formatting tidy up.
* st,sensors
- Drop duplicate text in DT binding.
* st,stm32-adc
- Add some missing static markings.
* ti,ads1100
- Use correct return code in dev_err_probe() call.
* x-powers,axp20x_adc - precursor series to simplify addition of AXP192.
- General code cleanup / minor refactoring for better readabilty of code.
- Switch from boolean value to mask for adc_en2 field to avoid hard coding
a mask that will be different in AXP192

The trigger_handler gets called from the IRQ thread handler using
iio_trigger_poll_chained() which will only call the bottom half of the
pollfunc and therefore pf->timestamp will not get set.
Use instead the timestamp from the driver's private data which is always
set in the IRQ handler.

We have finally managed to take the mlock mutex entirely private so as
to avoid it being used for multiple purposes. Now it is just used to
protect device mode transitions (typically to and from buffered capture).
Includes merge of an immutable i2c branch to get the new
i2c_client_get_device_id() (thanks to Wolfram for providing the branch).
Based on rc3 to pick up some precursor fixes from early in the cycle and
avoid an unnecessarily messy history.
New device support
* adi,ad4310
- New driver to support this very flexible measurement device including
a 24 bit ADC. Later fix for documentation build issue.
* adi,adxl355
- Add support of the ADXL359 accelerometer.
* adi,ltc2983
- Support additional variants of the temperatures sensor:
LTC2984 with an EEPROM
LTC2985, LTC2986 with only 10 channels.
* invensense,icm42600
- Add support for icm42631 (needed only ID and WHOAMI)
* kionix,kx022a
- New driver for this 3 axis accelerometer.

- Add support for stm32pm13x SoCs.
core / subsystem wide:
- Add new IIO_STATIC_CONST_DEVICE_ATTR() which is a dance necessary to
allow for the wrapping of attributes in the code that duplicates them
for multiple buffers.
- Harden against future issues with expectation that all buffer attributes
are iio_dev_attrs by changing the code to take an array of pointers
of the correct type.
- Last transitions of drivers to local locks rather than missuses of mlock.
- Add an iio_device_claim_buffer_mode() callback to avoid a race in the
max30100 driver without directly using mlock.
- Move mlock to the opaque IIO device structure to prevent misuse.
- Add missing spi_device_id tables to support auto loading of modules.
- Update some ADI maintainers in DT bindings.
- A few more moves of bus drivers and core module sets to export
name spaces.
- Extensive use of new devm_regulator_get_enable() and friends.
- Switch a bunch of i2c drivers to probe_new() including the bmp280
which makes use of the new i2c_client_get_device_id() helper to
simplify this change.
dt-bindings:
- More use of spi-peripheral-props.yaml.
Features
* freescale,mpl115
- Use runtime PM to implement shutdown GPIO support.
