- New feature of graceful hard-reset. Instead of immediately killing the
user-process when a command submission times out, we wait a bit and give
the user-process notification and let it try to close things gracefully,
with the ability to retrieve debug information.
- Enhance the EventFD mechanism. Add new events such as access to illegal
address (RAZWI), page fault, device unavailable. In addition, change the
event workqueue to be handled in a single-threaded workqueue.
- Allow the control device to work during reset of the ASIC, to enable
monitoring applications to continue getting the data.
- Add handling for Gaudi2 with PCI revision 2.
- Reduce severity of prints due to power/thermal events.
- Change how we use the h/w to perform memory scrubbing in Gaudi2.
- Multiple bug fixes, refactors and renames.

The ARR (auto reload register) and CMP (compare) registers are
successively written. The status bits to check the update of these
registers are polled together with regmap_read_poll_timeout().
The condition to end the loop may become true, even if one of the register
isn't correctly updated.
So ensure both status bits are set before clearing them.

If the userspace daemon is killed in the middle of an invoke (e.g.
audiopd listerner invoke), we need to skip the unmapping on device
release, otherwise the DSP will crash. So lets safekeep all the maps
only if there is in invoke interrupted, by attaching them to the channel
context (which is resident until RPMSG driver is removed), and free them
on RPMSG driver remove.

In order to be able to start the adsp listener for audiopd using adsprpcd,
we need to add the corresponding ioctl for creating a static process.
On that ioctl call we need to allocate the heap. Allocating the heap needs
to be happening only once and needs to be kept between different device
open calls, so attach it to the channel context to make sure that remains
until the RPMSG driver is removed. Then, if there are any VMIDs associated
with the static ADSP process, do a call to SCM to assign it.
And then, send all the necessary info related to heap to the DSP.

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.

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.

Prior to commit bd5d54e4d4 ("iio: adc128s052: add ACPI _HID
AANT1280"), the driver unconditionally used spi_get_device_id() to get
the index into the adc128_config array.
However, with that commit, OF-based boards now incorrectly treat all
supported sensors as if they are an adc128s052, because all the .data
members of the adc128_of_match table are implicitly 0. Our board,
which has an adc122s021, thus exposes 8 channels whereas it really
only has two.

Add smart calibration support for STM32MP1.
- STM32MP15x: both linear & offset calibration are supported
- STM32MP13x: Only offset calibration is supported
Linear calibration:
Linear calibration is SoC dependent and does not change over time
so it can be done only once.
Linear calibration may have already been done in u-boot.
Skip calibration execution if calibration data are already available.
Save calibration factors in private data and restore them from private
data on next ADC start.
Offset calibration:
This calibration may vary over time, depending on temperature or voltage.
Run offset single-ended and differential calibration on each ADC start,
as it is not time consuming. This calibration do not need to be saved.
So, remove calfact_s and calfact_d value and bitfields that are no
longer used.

We have a board where the reset pin of the ad74412 is connected to a
gpio, but also pulled low (i.e., asserted) by default. Hence to get
the chip out of reset, the driver needs to know about that gpio and
deassert the reset signal before attempting to communicate with the
chip.
When a reset-gpio is given in device tree, use that instead of the
software reset. According to the data sheet, the two methods are
functionally equivalent.

The constant AD74413R_ADC_RESULT_MAX is defined via GENMASK, so its
type is "unsigned long".
Hence in the expression voltage_offset * AD74413R_ADC_RESULT_MAX,
voltage_offset is first promoted to unsigned long, and since it may be
negative, that results in a garbage value. For example, when range is
AD74413R_ADC_RANGE_5V_BI_DIR, voltage_offset is -2500 and
voltage_range is 5000, so the RHS of this assignment is, depending on
sizeof(long), either 826225UL or 3689348814709142UL, which after
truncation to int then results in either 826225 or 1972216214 being
the output from in_currentX_offset.
Casting to int avoids that promotion and results in the correct -32767
output.

This fix is needed to remove a deadlock for all devices which are

The mutex is acquired once inside 'adis_initial_startup()', before
calling '__adis_initial_startup()', and once inside
