Move all DMA aligned buffers together at the end of the structure.
1. Timestamp anynomous structure is not used with DMA so it doesn't
belong after __aligned(IIO_DMA_MINALIGN).
2. struct inv_icm42600_fifo contains it's own __aligned(IIO_DMA_MINALIGN)
within it at the end so it should not be after __aligned(IIO_DMA_MINALIGN)
in the outer struct either.
3. Normally 1 would have been considered a bug, but because of the extra
alignment from 2, it actually was OK, but we shouldn't be relying on such
quirks.

The driver code is full of intXX_t and uintXX_t types which is
not the pattern we use in the IIO subsystem. Switch the driver
to use kernel internal types for that. No functional changes.

IIO: New device support, features and cleanup for 6.16 - take 2
Note - last minute rebase was to drop a typo patch that I'd accidentally
picked up (in the microblaze arch Kconfig)
Take 2 is due to that rebase messing up some fixes tags that were
referring to patches after that point.
There is a known merge conflict due to changes in neighbouring lines.
Stephen's resolution in linux-next is:
https://lore.kernel.org/linux-next/20250506155728.65605bae@canb.auug.org.au/
Added 3 named IIO reviewers to MAINTAINERS. This is a reflection of those
who have been doing much of this work for some time. Lars-Peter is
removed from the entry having moved on to other topics. Thanks
Nuno, David and Andy for stepping up and Lars-Peter for all your
hard work in the past!
Includes the usual mix of new device support, features and general
cleanup.
This time we also have some tree wide changes.
- Rip out the iio_device_claim_direct_scoped() as it proved hard to work
with. This series includes quite a few related cleanups such as use
of guard or factoring code out to allow direct returns.
- Switch from iio_device_claim/release_direct_mode() to new
iio_device_claim/release_direct() which is structured so that sparse
can warn on failed releases. There were a few false positives but
those were mostly in code that benefited from being cleaned up as part
of this process.
- Introduce iio_push_to_buffers_with_ts() to replace the _timestamp()
version over time. This version takes the size of the supplied buffer
which the core checks is at least as big as expected by calculation
from channel descriptions of those channels enabled. Use this in
an initial set of drivers.
- Add macros for IIO_DECLARE_BUFFER_WITH_TS() and
IIO_DECLARE_DMA_BUFFER_WITH_TS() to avoid lots of fiddly code to ensure
correctly aligned buffers for timestamps being added onto the end of
channel data.
New device support
------------------
adi,ad3530r
- New driver for AD3530, AD3530R, AD3531 and AD3531R DACs with
programmable gain controls. R variants have internal references.
adi,ad7476
- Add support (dt compatible only) for the Rohm BU79100G ADC which is
fully compatible with the ti,ads7866.
adi,ad7606
- Support ad7606c-16 and ad7606c-18 devices. Includes switch to dynamic
channel information allocation.
adi,ad7380
- Add support for the AD7389-4
dfrobot,sen0322
- New driver for this oxygen sensor.
mediatek,mt2701-auxadc
- Add binding for MT6893 which is fully compatible with already supported
MT8173.
meson-saradc
- Support the GXLX SoCs. Mostly this is a workaround for some unrelated
clock control bits found in the ADC register map.
nuvoton,nct7201
- New driver for NCT7201 and NCT7202 I2C ADCs.
rohm,bd79124
- New driver for this 12-bit, 8-channel SAR ADC.
- Switch to new set_rv etc gpio callbacks that were added in 6.15.
rohm,bd79703
- Add support for BD79700, BD79701 and BD79702 DACs that have subsets of
functionality of the already supported bd79703. Included making this
driver suitable for support device variants.
st,stm32-lptimer
- Add support for stm32pm25 to this trigger.
Features
--------
Beyond IIO
- Property iterator for named children.
core
- Enable writes for 64 bit integers used for standard IIO ABI elements.
Previously these could be read only.
- Helper library that should avoid code duplication for simpler ADC
bindings that have a child node per channel.
- Enforce that IIO_DMA_MINALIGN is always at least 8 (almost always true
and simplifies code on all significant architectures)
core/backend
- Add support to control source of data - useful when the HDL includes
things like generated ramps for testing purposes. Enable this for
adi-axi-dac
adi,ad3552-hs
- Add debugfs related callbacks to allow debug access to register contents.
adi,ad4000
- Support SPI offload with appropriate FPGA firmware along with improving
documentation.
adi,ad7293
- Add support for external reference voltage.
adi,ad7606
- Support SPI offload.

- Support filter frequencies beyond 2^32.
adi,adxl345
- Add single and double tap events.
hid-sensor-prox
- Support 16-bit report sizes as seen on some Intel platforms.
invensense,icm42600
- Enable use of named interrupts to avoid problems with some wiring choices.
Get the interrupt by name, but fallback to previous assumption on the first
being INT1 if no names are supplied.
microchip,mcp3911
- Add reset gpio support.
rohm,bh7150
- Add reset gpio support.
st,stm32
- Add support to control oversampling.
ti,adc128s052
- Add support for ROHM BD79104 which is early compatible with the TI
parts already supported by this driver. Includes some general driver
cleanup and a separate dt binding.
- Simplify reference voltage handling by assuming it is fixed after enabling
the supply.
winsen,mhz19b
- New driver for this C02 sensor.
Cleanup and minor fixes
-----------------------
dt-bindings
- Correct indentation and style for DTS examples.
- Use unevalutateProperties for SPI devices instead of additionalProperties
to allow generic SPI properties from spi-peripheral-props.yaml
ABI Docs
- Add missing docs for sampling_frequency when it applies only to events.
Treewide
- Various minor tweaks, comment fixes and similar.
- Sort TI ADCs in Kconfig that had gotten out of order.
- Switch various drives that provide GPIO chip functionality to the new
callbacks with return values.
- Standardize on { } formatting for all array sentinels.
- Make use of aligned_s64 in a few places to replace either wrong types
or manually defined equivalents.
- Drop places where spi bits_per_word is set to 8 because that is the
default anyway.
adi,ad_sigma_delta library
- Avoid a potential use of uninitialized data if reg_size has a value
that is not supported (no drivers hit this but it is reasonable hardening)
adi,ad4030
- Add error checking for scan types and no longer store it in state.
- Rework code to reduce duplication.
- Move setting the mode from buffer preenable() to update_scan_mode(),
better matching expected semantics of the two different callbacks.
- Improve data marshalling comments.
adi,ad4695
- Use u16 for buffer elements as oversampling is not yet supported except
with SPI offload (which doesn't use this path).
adi,ad5592r

- Use lock guards to simplify code (later patch fixes a missed unlock)
adi,ad5933
- Correct some incorrect settling times.
adi,ad7091

Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace
the array sentinel in all IIO drivers to the same style.
For some time, we've been trying to consistently use `{ }` (no trailing
comma, no comment, one space between braces) for array sentinels in the
IIO subsystem. Still nearly 50% of existing code uses a different style.
To save reviewers from having to request this trivial change as
frequently, let's normalize the style in all existing IIO drivers.
At least when code is copy/pasted to new drivers, the style will be
consistent.

aligned_s64
The vast majority of IIO drivers use aligned_s64 for the type of the
timestamp field. It is not a bug to use int64_t and until this series
iio_push_to_buffers_with_timestamp() took and int64_t timestamp, it
is inconsistent. This change is to remove that inconsistency and
ensure there is one obvious choice for future drivers.

When multiple ODR switch happens during FIFO off, the change could
not be taken into account if you get back to previous FIFO on value.
For example, if you run sensor buffer at 50Hz, stop, change to
200Hz, then back to 50Hz and restart buffer, data will be timestamped
at 200Hz. This due to testing against mult and not new_mult.
To prevent this, let's just run apply_odr automatically when FIFO is
off. It will also simplify driver code.
Update inv_mpu6050 and inv_icm42600 to delete now useless apply_odr.

Add ODRs accessible only in low-power mode. Switch automatically to
low-power or low-noise depending on the ODR set.
Add channel attributes "power_mode" and "power_mode_available" for
setting the power mode to use (low-noise or low-power) for ODRs
supporting both mode. Reading "power_mode" when the sensor is on
will return the actual mode and not the requested one. It will be
different when using ODRs not supported by the requested mode.
Use low-power mode by default.

register access. Now with caching, it happens only when changing bank
which is very infrequent.

Use IRQF_ONESHOT flag to ensure the timestamp is not updated in the
hard handler during the thread handler. And compute and use the
effective watermark value that correspond to this first timestamp.
This way we can ensure the timestamp is always corresponding to the
value used by the timestamping mechanism. Otherwise, it is possible
that between FIFO count read and FIFO processing the timestamp is
overwritten in the hard handler.

We are currently synchronizing every time the data timestamp with
the IT timestamp, leading to system jitter jamming timestamps.
To fix that and keep it simple, let's just synchronize when the
delta is bigger than the acceptable jitter, and keep
synchronization at the jitter value.
The result is much stable timestamps reflecting better the real
physical value. Example @50Hz delta timestamp,
* before: 20.123ms, 19.721ms, 20.023ms, 20.353ms, 19.821ms, ...
* after: 20.173ms, 20.173ms, 20.173ms, 20.40ms, 20.173ms, ...
Refactorize code and delete the unnecessary handling of multiple
FIFO data.

Timestamp reset is not done in the correct place. It must be done
before enabling buffer. The reason is that interrupt timestamping
is always happening when the chip is on, even if the
corresponding sensor is off. When the sensor restarts, timestamp
is wrong if you don't do a reset first.

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.

* vl53l0x
- Make the VDD regulator optional by allowing a dummy regulator.

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
controller. So we don't test the return value.

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.

conversion.
Cast to a uintptr_t rather than directly to the enum.
As per the discussion in below linked media patch.

All of the users of iio_read_mount_matrix() are using the very same
property name. Moreover, the property name is hard coded in the API
documentation.
Make this clear and avoid duplication now and in the future.

All drivers that already call devm_iio_kfifo_allocate() &
iio_device_attach_buffer() are simple to convert to
iio_device_attach_kfifo_buffer() in a single go.
This change does that; the unwind order is preserved.
What is important, is that the devm_iio_kfifo_buffer_setup() be called
after the indio_dev->modes is assigned, to make sure that
INDIO_BUFFER_SOFTWARE flag is set and not overridden by the assignment to
indio_dev->modes.
Also, the INDIO_BUFFER_SOFTWARE has been removed from the assignments of
'indio_dev->modes' because it is set by devm_iio_kfifo_buffer_setup().
