4a8e1e020a iio: accel: mxc4005: Read orientation matrix from ACPI ROTM method
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.

Replace the duplicate ACPI "ROTM" data parsing code with the new
shared iio_read_acpi_mount_matrix() helper.

This also removes the limiting of the "ROTM" mount matrix to only ACPI
devices with an ACPI HID (Hardware-ID) of "KIOX000A". If kxcjk-1013 ACPI
devices with another HID have a ROTM method that should still be parsed
and if the method is not there then iio_read_acpi_mount_matrix() will
fail silently.

Add a setup function implementation to the spi module to enable spi-3wire
when specified in the device-tree. If spi-3wire is not specified in the
device-tree, NULL is returned as bus pre-initialization. This behavior
is identical to the i2c initialization, hence the default initialization.

57a1592784 iio: accel: mxc4005: Interrupt handling fixes
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.

d4551c189d 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.
 
 Cleanup
 =======
 Various minor typo fixes and better use of defines etc.
 
 Treewide
 - Stop using ACPI_PTR(). The savings in space are small and not worth
   the complexity of __maybe_unused of ifdef guards.  To avoid use in
   new IIO drivers based on copy and paste, clean it out.
 - cleanup.h based handling of iio_device_claim_direct_mode()/
   iio_device_release_direct_mode() using scope_cond_guard().
   In many drivers this is combined with other automated cleanup
   to give maximum simplifications.
   An initial set of drivers are converted over to this infrastructure.
 
 Tools
 - Use rewinddir() instead of seekdir() to return to start of file.
 
 core
 - Make iio_bus_type constant.
 
 adi,ad16475
 - Use irq_get_trigger_type() instead of opencoding.
 adi,ad16480
 - Use irq_get_trigger_type() instead of opencoding.
 adi,ad-sigma-delta
 - Avoid overwriting IRQ flags if provided by firmware.
 ams,as73211
 - Use IIO_VAL_FRACTIONAL for scales to simplify the code and potentially
   improve accuracy.
 gts-library
 - Use a div64_u64() instead of a loop to do a division.
 honeywell,mprls00025pa
 - Clean up dt-binding doc.
 - Drop defaults when DT binding not providing values. Very unlikely
   these were useful given they were wrong for vast majority of supported
   devices.
 - Whitespace cleanup
 miramems,da280
 - Use i2c_get_match_data() to replace hand rolled ACPI matching code.
 semtech,sx9324
 - Avoid unnecessary copying of property strings.
 st,lsm6dsx
 - Improve docs, particularly wrt to making addition of new device
   support less noisy.
 st,lsm9ds0
 - Use dev_err_probe() in all probe() error handling.
 - Improved header includes.
 - Tidy up termination of ID tables.
 ti,ads1014
 - Correct upper bound on PGA (wrong value had no actual impact)
 ti,afe4403/4404
 - devm_ useage to simplify error handling in probe() and allow() remove to
   be dropped.
 voltage-divider
 - Add dt-binding for io-channel-cells to allow such a device to be both

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.

Cleanup
=======
Various minor typo fixes and better use of defines etc.

Treewide
- Stop using ACPI_PTR(). The savings in space are small and not worth
  the complexity of __maybe_unused of ifdef guards.  To avoid use in
  new IIO drivers based on copy and paste, clean it out.
- cleanup.h based handling of iio_device_claim_direct_mode()/
  iio_device_release_direct_mode() using scope_cond_guard().
  In many drivers this is combined with other automated cleanup
  to give maximum simplifications.
  An initial set of drivers are converted over to this infrastructure.

Tools
- Use rewinddir() instead of seekdir() to return to start of file.

core
- Make iio_bus_type constant.

adi,ad16475
- Use irq_get_trigger_type() instead of opencoding.
adi,ad16480
- Use irq_get_trigger_type() instead of opencoding.
adi,ad-sigma-delta
- Avoid overwriting IRQ flags if provided by firmware.
ams,as73211
- Use IIO_VAL_FRACTIONAL for scales to simplify the code and potentially
  improve accuracy.
gts-library
- Use a div64_u64() instead of a loop to do a division.
honeywell,mprls00025pa
- Clean up dt-binding doc.
- Drop defaults when DT binding not providing values. Very unlikely
  these were useful given they were wrong for vast majority of supported
  devices.
- Whitespace cleanup
miramems,da280
- Use i2c_get_match_data() to replace hand rolled ACPI matching code.
semtech,sx9324
- Avoid unnecessary copying of property strings.
st,lsm6dsx
- Improve docs, particularly wrt to making addition of new device
  support less noisy.
st,lsm9ds0
- Use dev_err_probe() in all probe() error handling.
- Improved header includes.
- Tidy up termination of ID tables.
ti,ads1014
- Correct upper bound on PGA (wrong value had no actual impact)
ti,afe4403/4404
- devm_ useage to simplify error handling in probe() and allow() remove to
  be dropped.
voltage-divider
- Add dt-binding for io-channel-cells to allow such a device to be both
  an IIO consumer and IIO producer at the same time.

042ffa6daf iio: st_sensors: drop ACPI_PTR() and CONFIG_ACPI guards
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.

3b63f5e8f7 iio: accel: bmc150: Drop ACPI_PTR()
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.

dt-bindings: iio: Add KX132ACR-LBZ accelerometer

ROHM KX132ACR-LBZ is an accelerometer for industrial applications. It
has a subset of KX022A functionalities, dropping support for tap, free
fall and tilt detection engines. Also, the register interface is an exact
subset of what is found on KX022A (except the WHO_AM_I register value).

Add support for KX132ACR-LBZ.

53cb25c97b iio: accel: hid-sensor-accel-3d: Convert to platform remove callback returning void
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

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

56cd3d1c5c iio: accel: kx022a fix irq getting
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.

a508fbfed3 iio: kx022a: Probe asynchronously
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/

Enable asynchronous probing for KX022A.

79b8ded9d9 iio: accel: st_accel: Fix invalid mount_matrix on devices without ACPI _ONT method
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.

  Fix IRQ type.  Not confirmed to have any impact but good to correct it anyway

- adi,adis16400
  Missing CONFIG_CRC32

- capella,cm32181
  Unregister 2nd I2C client if one is used.

- cio-dac
  Fix bitdepth for range check on write.

- linear,ltc2497
  Fix a wrong shift of the LSB introduced when switching to be24 handling.

- maxim,max11410
  Fix handling of return code in read_poll_timeout()

- qcom,spmi-adc
  Fix an accidental change of channel name to include the reg value from OF.

- ti,palmas
  Fix a null dereference on remove due to wrong function used to get the
  drvdata.

- ti,ads7950
  Mark GPIO as can sleep.

03fada4731 iio: accel: kionix-kx022a: Get the timestamp from the driver's private data in the trigger_handler
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.

56d784d177 1st set of IIO new device support, feature and cleanup for 6.2 (take2)
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.
 * maxim,max11401
   - New driver to support this 24-bit 10 channel ADC.
     Includes some new ABI to support configuration of notch filters.
 * mediatek,mt6370
   - Add new driver to support the ADC part of the mt6370.
 * st,lsm6dsx
   - Add support for LSM6DSV accelerometer and gyroscope. Simple additional
     of chip specific data and IDs.
   - Add support for LSM6DSV16X accelerometer and gyroscope.  Compatible with
     features currently implemented for the LSM6DSV.
 * st,stm32-adc
   - 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.
 * melexis,mlx90632
   - More sophisticated runtime power management
   - Provide access to sampling frequency.
   - Trivial follow up fixes.
 * microchip,mcp3911
   - Support control of PGA.
 * st,lsm6dsx
   - Add support for software triggers for cases where the IRQ lines
     are not wired up.
 * vishay,vcnl4000
   - Add control of integration time.
 
 Minor cleanups and fixes
 * adi,ad4130
   - Improve ABI documentation formatting.
   - Kconfig dependency fixup.
 * adi,ad5758
   - Minor dt binding fix.
 * adi,ad9834

Merge tag 'iio-for-6.2a-take2' of https://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into char-misc-next

Jonathan writes:

1st set of IIO new device support, feature and cleanup for 6.2 (take2)

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.
* maxim,max11401
  - New driver to support this 24-bit 10 channel ADC.
    Includes some new ABI to support configuration of notch filters.
* mediatek,mt6370
  - Add new driver to support the ADC part of the mt6370.
* st,lsm6dsx
  - Add support for LSM6DSV accelerometer and gyroscope. Simple additional
    of chip specific data and IDs.
  - Add support for LSM6DSV16X accelerometer and gyroscope.  Compatible with
    features currently implemented for the LSM6DSV.
* st,stm32-adc
  - 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.
* melexis,mlx90632
  - More sophisticated runtime power management
  - Provide access to sampling frequency.
  - Trivial follow up fixes.
* microchip,mcp3911
  - Support control of PGA.
* st,lsm6dsx
  - Add support for software triggers for cases where the IRQ lines
    are not wired up.
* vishay,vcnl4000
  - Add control of integration time.

Minor cleanups and fixes
* adi,ad4130
  - Improve ABI documentation formatting.
  - Kconfig dependency fixup.
* adi,ad5758
  - Minor dt binding fix.
* adi,ad9834
  - Tidy up line breaks.
* adi,ade7854
  - Minor improvement in code clarity by replacing a ternary.
* adi,admv8818
  - Harden code against hardware returning wrong values.
* adi,adxl355
  - Warn only if unknown device ID detected to allow for fall back
    device tree compatibles on future devices.
* adi,ltc2983
  - dt-bindings clarifications and general improvements.
  - Ensure DMA safe buffer for bulk writes without relying on current
    regmap implementation choices.
* avago,adps9960
  - Fix up a disconnect between event enable attributes and what was
    enabled.

0a33755c4b iio: Don't silently expect attribute types
The iio_triggered_buffer_setup_ext() and the
devm_iio_kfifo_buffer_setup_ext() were changed by
commit 15097c7a1a ("iio: buffer: wrap all buffer attributes into iio_dev_attr")
to silently expect that all attributes given in buffer_attrs array are
device-attributes. This expectation was not forced by the API - and some
drivers did register attributes created by IIO_CONST_ATTR().

When using IIO_CONST_ATTRs the added attribute "wrapping" does not copy
the pointer to stored string constant and when the sysfs file is read the
kernel will access to invalid location.

Change the function signatures to expect an array of iio_dev_attrs to
avoid similar errors in the future.

Merge conflict resolved whilst applying due to patch crossing with
two new drivers (kx022a accelerometer and ad4130 ADC).

KX022A is a 3-axis accelerometer from ROHM/Kionix. The sensor features
include variable ODRs, I2C and SPI control, FIFO/LIFO with watermark IRQ,
tap/motion detection, wake-up & back-to-sleep events, four acceleration
ranges (2, 4, 8 and 16g), and probably some other cool features.

Add support for the basic accelerometer features such as getting the
acceleration data via IIO. (raw reads, triggered buffer [data-ready] or
using the WMI IRQ).

Important things to be added include the double-tap, motion
detection and wake-up as well as the runtime power management.

a10a0f385a iio: bmc150-accel-core: Fix unsafe buffer attributes
The iio_triggered_buffer_setup_ext() was changed by
commit 15097c7a1a ("iio: buffer: wrap all buffer attributes into iio_dev_attr")
to silently expect that all attributes given in buffer_attrs array are
device-attributes. This expectation was not forced by the API - and some
drivers did register attributes created by IIO_CONST_ATTR().

The added attribute "wrapping" does not copy the pointer to stored
string constant and when the sysfs file is read the kernel will access
to invalid location.

Change the IIO_CONST_ATTRs from the driver to IIO_DEVICE_ATTR in order
to prevent the invalid memory access.

ed5c2f5fd1 i2c: Make remove callback return void
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.

3cfb0e1d39 iio: accel: sca3300: Extend the trigger buffer from 16 to 32 bytes
After added inclination angle channels, the trigger buffer size is
insufficient. Extend the buffer size from 16 to 32 bytes, and change
the trigger buffer from the struct to a u8 array to adapt the sensor
with/without inclination angles output.
New trigger buffer data:
  - SCA3300: 3 accel channels, temp, and timestamp.
  - SCL3300: 3 accel channels, temp, 3 incli channels, and timestamp.
Readjustment the scan index to make it consistent with the buffer data.

Instead of registering callback to process sensor events right at

Events can come at probe time (in case the kernel rebooted abruptly

before the sensor is fully registered.

2a3c8f8a44 IIO new device support, features and minor fixes for 5.20
Several on-running cleanup efforts dominate this time, plus the DMA
 safety alignment issue identified due to improved understanding of
 the restrictions as a result of Catalin Marinas' efforts in that area.
 
 One immutable branch in here due to MFD and SPMI elements needed for
 the qcom-rradc driver.
 
 Device support
 * bmi088
   - Add support for bmi085 (accelerometer part of IMU)
   - Add support for bmi090l (accelerometer part of IMU)
 * mcp4922
   - Add support for single channel device MCP4921
 * rzg2l-adc
   - Add compatible and minor tweaks to support RZ/G2UL ADC
 * sca3300
   - Add support for scl3300 including refactoring driver to support
     multiple device types and cleanup noticed whilst working on driver.
 * spmi-rradc
   - New driver for Qualcomm SPMI Round Robin ADC including necessary
     additional utility functions in SPMI core and related MFD driver.
 * ti-dac55781
   - Add compatible for DAC121C081 which is very similar to existing parts.
 
 Features
 * core
   - Warn on iio_trigger_get() on an unregistered IIO trigger.
 * bma400
   - Triggered buffer support
   - Activity and step counting
   - Misc driver improvements such as devm and header ordering
 * cm32181
   - Add PM support.
 * cros_ec
   - Sensor location support
 * sx9324
   - Add precharge resistor setting
   - Add internal compensation resistor setting
   - Add CS idle/sleep mode.
 * sx9360
   - Add precharge resistor setting
 * vl53l0x
   - Handle reset GPIO, regulator and relax handling of irq type.
 
 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
   header and Kconfig issues.
 - Drop include of of.h from iio.h and fix up drivers that need to include
   it directly.
 - 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
   than every driver in future. Note, there have been no reports of this
   bug in the wild, and it may not happen on any platforms supported by
   upstream, so no rush to backport these fixes.
 
 Other cleanup
 * core
   - Switch to ida_alloc()/free()
   - Drop unused iio_get_time_res()
   - Octal permissions and DEVICE_ATTR_* macros.
   - Cleanup bared unsigned usage.
 * MAINTAINERS
   - Add include/dt-bindings/iio/ to the main IIO entry.
 * ad5380
   - Comment syntax fix.
 * ad74413r
   - Call to for_each_set_bit_from(), with from value as 0 replaced.
 * ad7768-1
   - Drop explicit setting of INDIO_BUFFER_TRIGGERED as now done by the core.
 * adxl345
   - Fix wrong address in dt-binding example.
 * adxl367
   - Drop extra update of FIFO watermark.
 * at91-sama5d2
   - Limit requested watermark to the hwfifo size.
 * bmg160, bme680
   - Typos
 * cio-dac
   - Switch to iomap rather than direct use of ioports
 * kxsd9
   - Replace CONFIG_PM guards with new PM macros that let the compiler
     cleanly remove the unused code and structures when !CONFIG_PM
 * lsm6dsx
   - Use new pm_sleep_ptr() and EXPORT_SIMPLE_DEV_PM_OPS(). Then move
     to Namespace.
 * meson_saradc - general cleanup.
   - Avoid attaching resources to iio_dev->dev
   - Use same struct device for all error messages
   - Convert to dev_err_probe() and use local struct device *dev to
     reduce code complexity.
   - Use devm_clk_get_optional() instead of hand rolling.
   - Use regmap_read_poll_timeout() instead of hand rolling.
 * mma7660
   - Drop ACPI_PTR() use that is unhelpful.

12c4efe350 iio: core: Fix IIO_ALIGN and rename as it was not sufficiently large
Discussion of the series:
https://lore.kernel.org/all/20220405135758.774016-1-catalin.marinas@arm.com/
mm, arm64: Reduce ARCH_KMALLOC_MINALIGN brought to my attention that
our current IIO usage of L1CACHE_ALIGN is insufficient as their are Arm
platforms out their with non coherent DMA and larger cache lines at
at higher levels of their cache hierarchy.

Rename the define to make it's purpose more explicit. It will be used
much more widely going forwards (to replace incorrect ____cacheline_aligned
markings.

Note this patch will greatly reduce the padding on some architectures
that have smaller requirements for DMA safe buffers.

The history of changing values of ARCH_KMALLOC_MINALIGN via
ARCH_DMA_MINALIGN on arm64 is rather complex. I'm not tagging this
as fixing a particular patch from that route as it's not clear what to tag.

Most recently a change to bring them back inline was reverted because
of some Qualcomm Kryo cores with an L2 cache with 128-byte lines
sitting above the point of coherency.

c1132702c7 Revert "arm64: cache: Lower ARCH_DMA_MINALIGN to 64 (L1_CACHE_BYTES)"
That reverts:
65688d2a05 arm64: cache: Lower ARCH_DMA_MINALIGN to 64 (L1_CACHE_BYTES) which
refers to the change originally being motivated by Thunder x1 performance
rather than correctness.

Currently, the driver updates the FIFO watermark inside both
update_scan_mode() and hwfifo_set_watermark(). Inside the IIO core,
hwfifo_set_watermark() is called immediately after update_scan_mode(),
making the first call to set_fifo_samples() redundant.

Remove the first call to set_fifo_samples(), and merge the
set_fifo_samples() function into the set_fifo_watermark()
function. Also, since fifo_set_size is always set inside of
update_scan_mode(), and it cannot be set to 0, remove the
zero check from set_fifo_samples().

12c99f859f iio: accel: bma400: conversion to device-managed function
This is a conversion to device-managed by using devm_iio_device_register()
inside probe function. Previously the bma400 was not put into power down
mode in some error paths in probe where it now is, but that should cause
no harm.

The dev_set_drvdata() call, bma400_remove() function and hooks in the I2C
and SPI driver struct is removed as devm_iio_device_register() function is
used to automatically unregister on driver detach.

1db6926d61 iio:accel:stk8ba50: Remove duplicated error reporting in .remove()
Returning an error value in an i2c remove callback results in an error
message being emitted by the i2c core, but otherwise it doesn't make a
difference. The device goes away anyhow and the devm cleanups are
called.

As stk8ba50_set_mode() already emits an error message on failure and the
additional error message by the i2c core doesn't add any useful
information, change the return value to zero to suppress this message.

This patch is a preparation for making i2c remove callbacks return void.

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.

 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

 Otherwise it's been a relatively quiet release with some new device

 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

cc6ce5ac2c 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)

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.

c87b7b12f4 iio: accel: mma8452: use the correct logic to get mma8452_data
The original logic to get mma8452_data is wrong, the *dev point to
the device belong to iio_dev. we can't use this dev to find the
correct i2c_client. The original logic happen to work because it
finally use dev->driver_data to get iio_dev. Here use the API
to_i2c_client() is wrong and make reader confuse. To correct the
logic, it should be like this

  struct mma8452_data *data = iio_priv(dev_get_drvdata(dev));

But after commit 8b7651f259 ("iio: iio_device_alloc(): Remove
unnecessary self drvdata"), the upper logic also can't work.
When try to show the avialable scale in userspace, will meet kernel
dump, kernel handle NULL pointer dereference.

So use dev_to_iio_dev() to correct the logic.

Dual fixes tags as the second reflects when the bug was exposed, whilst
the first reflects when the original bug was introduced.

Fixes: c3cdd6e48e ("iio: mma8452: refactor for seperating chip specific data")
Fixes: 8b7651f259 ("iio: iio_device_alloc(): Remove unnecessary self drvdata")
