5532cd9d1d iio: gyro: Use aligned_s64 instead of open coding alignment.
Use this new type to both slightly simplify the code and avoid
confusing static analysis tools. Mostly this series is about consistency
to avoid this code pattern getting copied into more drivers.

fa13ac6cdf iio: gyro: fxas21002c: Fix missing data update in trigger handler
The fxas21002c_trigger_handler() may fail to acquire sample data because
the runtime PM enters the autosuspend state and sensor can not return
sample data in standby mode..

Resume the sensor before reading the sample data into the buffer within the
trigger handler. After the data is read, place the sensor back into the
autosuspend state.

b4b42f28a0 iio: fix write_event_config signature
write_event_config callback use an int for state, but it is actually a
boolean. iio_ev_state_store is actually using kstrtobool to check user
input, then gives the converted boolean value to write_event_config.

Fix signature and update all iio drivers to use the new signature.

This patch has been partially written using coccinelle with the
following script:

$ cat iio-bool.cocci
// Options: --all-includes

virtual patch

@c1@
identifier iioinfo;
identifier wecfunc;

 static const struct iio_info iioinfo = {

        .write_event_config =

 &wecfunc
),
        ...,
 };

 }

make coccicheck MODE=patch COCCI=iio-bool.cocci M=drivers/iio

Unfortunately, this script didn't match all files:
* all write_event_config callbacks using iio_device_claim_direct_scoped
  were not detected and not patched.
* all files that do not assign and declare the write_event_config
  callback in the same file.

iio.h was also manually updated.

The patch was build tested using allmodconfig config.

The to be removed IDs has been checked against the following resources:
1) DuckDuckGo
2) Google
3) MS catalog: https://www.catalog.update.microsoft.com/Search.aspx
This gives no useful results in regard to DSDT, moreover, the official

6a9262edff iio: Switch back to struct platform_driver::remove()
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.

4391affa10 iio: Drop explicit initialization of struct i2c_device_id::driver_data to 0
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.

3a8799735b iio: gyro: hid-sensor-gyro-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.

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.

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.
* mpu3050
  - Stop exporting symbols not used outside of module
  - Switch to new DEFINE_RUNTIME_DEV_PM_OPS() macro and move to Namespace.
* ping
  - Typo fix
* qcom-spmi-rradc
  - Typo fix
* sc27xx
  - Convert to generic struct u32_fract
* srf08
  - Drop a redundant check on !val

* stx104
  - Switch to iomap rather than direct use of ioports
* tsc2046
  - Drop explicit setting of INDIO_BUFFER_TRIGGERED as now done by the core.
* tsl2563
  - Replace flush_scheduled_work() with cancel_delayed_work_sync()
  - Replace cancel_delayed_work() with cancel_delayed_work_sync()
* vl53l0x
  - Make the VDD regulator optional by allowing a dummy regulator.
