After commit 6f110a5e4f99 ("Disable SLUB_TINY for build testing"), which
causes CONFIG_KASAN to be enabled in allmodconfig again, arm64
allmodconfig builds with older versions of clang (15 through 17) show an
instance of -Wframe-larger-than (which breaks the build with
CONFIG_WERROR=y):
drivers/staging/rtl8723bs/core/rtw_security.c:1287:5: error: stack frame size (2208) exceeds limit (2048) in 'rtw_aes_decrypt' [-Werror,-Wframe-larger-than]
1287 | u32 rtw_aes_decrypt(struct adapter *padapter, u8 *precvframe)
| ^
This comes from aes_decipher() being inlined in rtw_aes_decrypt().
Running the same build with CONFIG_FRAME_WARN=128 shows aes_cipher()
also uses a decent amount of stack, just under the limit of 2048:
drivers/staging/rtl8723bs/core/rtw_security.c:864:19: warning: stack frame size (1952) exceeds limit (128) in 'aes_cipher' [-Wframe-larger-than]
864 | static signed int aes_cipher(u8 *key, uint hdrlen,
| ^
-Rpass-analysis=stack-frame-layout only shows one large structure on the
stack, which is the ctx variable inlined from aes128k128d(). A good
number of the other variables come from the additional checks of
fortified string routines, which are present in memset(), which both
aes_cipher() and aes_decipher() use to initialize some temporary
buffers. In this case, since the size is known at compile time, these
additional checks should not result in any code generation changes but
allmodconfig has several sanitizers enabled, which may make it harder
for the compiler to eliminate the compile time checks and the variables
that come about from them.
The memset() calls are just initializing these buffers to zero, so use
'= {}' instead, which is used all over the kernel and does the exact
same thing as memset() without the fortify checks, which drops the stack
usage of these functions by a few hundred kilobytes.

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.
adi,ad7768-1
- Support reset GPIO.
adi,admv8818
- 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
- Clean up destruction of mutexes.
- Use lock guards to simplify code (later patch fixes a missed unlock)
adi,ad5933
- Correct some incorrect settling times.
adi,ad7091
- Deduplicate handling of writable vs volatile registers as they are the
inverse of each other for this device.
adi,ad7124
- Fix 3db Filter frequency.
- Remove ability to directly write the filter frequency (which was broken)
- Register naming improvements.
adi,ad7606
- Add a missing return value check.
- Fill in max sampling rates for all chips.
- Use devm_mutex_init()
- Fix up some kernel-doc formatting issues.
- Remove some camel case that snuck in.
- Drop setting address field in channels as easily established from other
fields.
- Drop unnecessary parameter to ad76060_scale_setup_cb_t.
adi,ad7768-1
- Convert to regmap.
- Factor out buffer allocation.
- Tidy up headers.
adi,ad7944
- Stop setting bits_per_word in SPI xfers with no data.
adi,ad9832
- Add of_device_id table rather than just relying on fallbacks.
- Use FIELD_PREP() to set values of fields.
adi,admv1013
- Cleanup a pointless ternary.
adi,admv8818
- Fix up LPF Band 5 frequency which was slightly wrong.
- Fix an integer overflow.
- Fix range calculation
adi,adt7316
- Replace irqd_get_trigger_type(irq_get_irq_data()) with simpler
irq_get_trigger_type()
adi,adxl345
- Use regmap cache instead of various state variables that were there to
reduce bus accesses.
- Make regmap return value checking consistent across all call sites.
adi,axi-dac
- Add a check on number of channels (0 to 15 valid)
allwinner,sun20i
- Use new adc-helpers to replace local parsing code for channel nodes.
bosch,bmp290
- Move to local variables for sensor data marshalling removing the need
for a messy definition that has to work for all supported parts.
Follow up fix adds a missing initialization.
dynaimage,al3010 and dynaimage,al3320a
- Various minor cleanup to bring these drivers inline with reviewed feedback
given on a new driver.
- Fix an error path in which power down is not called when it should be.
- Switch to regmap.
google,cros_ec
- Fix up a flexible array in middle of structure warning.
- Flush fifo when changing the timeout to avoid potential long wait
for samples.
hid-sensor-rotation
- Remove an __aligned(16) marking that doesn't seem to be justified.
kionix,kxcjk-1013
- Deduplicate code for setting up interrupts.
microchip,mcp3911
- Fix handling of conversion results register which differs across supported
devices.
idt,zopt2201
- Avoid duplicating register lists as all volatile registers are the
inverse of writeable registers on this device.
renesas,rzg2l
- Use new adc-helpers to replace local parsing code for channel nodes.
ti,ads1298
- Fix a missing Kconfig dependency.

The "media: atomisp: Add support for sensors with a separate ISP
v4l2_subdev" combined with some pending drivers/media/i2c/mt9m114.c changes
makes the atomisp work nicely with the standard V4L2 mt9m114.c driver,
avoiding the need for the atomisp specific atomisp-mt9m114 driver.
The normal driver actually works better since the atomisp-mt9m114 driver
does not have working exposure control, leading to a much too dark image.
Remove the no longer necessary atomisp-mt9m114 driver.

Some sensors have an ISP inside the sensor which the sensor driver models
as a separate v4l2-subdev, like the mt9m114 sensor-driver does.
Since the atomisp driver emulates a standard /dev/video# v4l2-device
without requiring the application to be aware of media-controller centric
/dev/video# devices this requires some special handling in the driver.
Add support for this setup to the atomisp driver.

When a (sensor) v4l2_subdev has its state_lock member set to non NULL,
then all v4l2_subdev_state-s for the sensor share the same lock.
atomisp_init_sensor() calls v4l2_subdev_lock_and_get_active_state() and
then later on also tries to lock a separate v4l2_subdev_state used for try
calls (rather then changing the active state), while still holding
the active state lock.
Since this try v4l2_subdev_state shares a lock with the active state this
results in a deadlock.
Skip locking try_sd_state when sensor->state_lock is set to avoid this.

atomisp_try_fmt() is limiting the width of the requested resolution to 1920
before calling the sensor's try_fmt() method. But it is not limiting
the height. In case of the old mode-list based t4ka3 driver which has
a mode list of:
736x496
896x736
1936x1096
3280x2464
This results in 3280x2464 being selected when try_fmt is called
with a requested resolution of 3280x2464, which is not supported because
its width > 1920 .
Fix this by also limiting the height when in preview mode.

The GMIN code has support for sensors using external regulators enabled
by GPIOS, rather then using regulators build into the PMIC.
With the exception of the Trekstor ST70408-4 (1) tablet there are no known
devices which actually use external regulators for the sensors and the code
for this is using deprecated old style GPIO numbers support for which is
going away.
Remove the GPIO driven regulator support so that the gmin code no longer
depends on deprecated GPIO APIs.
1) The GMIN support itself is also deprecated and all sensor drivers still
using it are being moved over to use ACPI + runtime-pm and the ST70408-4
shipped with Android as factory OS and thus will have broken ACPI tables
for the sensors, so like other Android factory OS tablets it will need
a bespoke solution anyways.

The IEEE-488 GPIB standard was designed to ensure that there is only ever
one controller-in-charge on the bus at any one time. If a board becomes
controller-in-charge on request_system_control there is no way to ensure
that there is not another board also acting as controller-in-charge.
This can lead to bus conflicts and hangs.
Remove the setting of controller-in-charge from request_system_control.
