A delay is needed each time the chip selected becomes inactive,
even after burst data readings are performed.
Currently, there is no delay added after a burst reading
and in case a new SPI transfer is performed before
the needed delay, the adis device becomes unresponsive until
reset.
This commit is adding the needed delay directly to the spi driver,
using the cs_inactive parameter, in case it is not set and is
removing the additional chip select change delay present in adis
APIs to remove the double delay.

The Bosch BMI323 is a 6-axis low-power IMU that provide measurements for
acceleration, angular rate, and temperature. This sensor includes
motion-triggered interrupt features, such as a step counter, tap detection,
and activity/inactivity interrupt capabilities.
The driver supports various functionalities, including data ready, FIFO
data handling, and events such as tap detection, step counting, and
activity interrupts.

Particularly great to see a resolver driver move out of staging via a
massive set of changes. Only took 13 years :)
One small patch added then reverted due to a report of test breakage
(ashai-kasei,ak8975: Drop deprecated enums.)
An immutable branch was used for some hid-senors changes in case
there was a need to take them into the HID tree as well.
New device support

Some devices do not support delta angle and delta velocity
burst readings, which means there should be no buffer support
for these types of channels.
A new list of channels is created which contains the delta
channels structures with the scan index equal to -1 to allow
for raw register readings, without buffer support.
This list of channels is assigned to the devices which
do not support delta angle and delta velocity burst
readings.

When processing data read the full fifo data in 1 time. If there
are several samples in the FIFO, it means we are experiencing
system delay. In this case, it is better to read all data with 1
bus access than to add additional latency by doing several ones.
This requires to use a bigger buffer depending on chip FIFO size
and do an additional local data copy before sending. But the cost
is minimal and behavior is still better like this under system
heavy load.

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.

The Invensense ICM-20600 is a 6-axis MotionTracking device that combines a
3-axis gyroscope and an 3-axis accelerometer. It is very similar to the
ICM20602 imu which is already supported by the mpu6050 driver. The main
difference is that the ICM-20600 has a different WHOAMI value.

Here is the "big" set of char/misc and other driver subsystems for
6.4-rc1.
It's pretty big, but due to the removal of pcmcia drivers, almost breaks
even for number of lines added vs. removed, a nice change.
Included in here are:
- removal of unused PCMCIA drivers (finally!)
- Interconnect driver updates and additions
- Lots of IIO driver updates and additions
- MHI driver updates
- Coresight driver updates
- NVMEM driver updates, which required some OF updates
- W1 driver updates and a new maintainer to manage the subsystem
- FPGA driver updates
- New driver subsystem, CDX, for AMD systems
- lots of other small driver updates and additions
All of these have been in linux-next for a while with no reported
issues.

A fairly standard release for SPI with the exception of a change to the
API for specifying chip selects done in preparation for supporting
devices with more than one chip select, this required some mechanical
changes throughout the tree which have been cooking in -next happily for
a while. There's also a new API to allow us to TPM chips on half duplex
controllers.
There's three commits in here that were mangled by a bad interaction
between the alsa-devel mailing list software and b4, I didn't notice
until there were merges on top with it being SPI not ALSA. It seemed
clear enough to not be worth going back and fixing.
- Refactoring in preparation for supporting multiple chip selects for a
single device, needed by some flash devices, which required a change
in the SPI device API visible throughout the tree.
- Support for hardware assisted interaction with SPI TPMs on half
duplex controllers, implemented on nVidia Tedra210 QuadSPI.
- Optimisation for large transfers on fsl-cpm devices.
- Cleanups around device property use which fix some sisues with
fwnode.
- Use of both void remove() and devm_platform_.*ioremap_resource().
- Support for AMD Pensando Elba, Amlogic A1, Cadence device mode,
Intel MetorLake-S and StarFive J7110 QuadSPI.
The final commit converting to DEV_PM_OPS() was applied late to fix a
warning that was introduced by some of the earlier work.

* st,sensors
- Drop duplicate text in DT binding.
* st,stm32-adc
- Add some missing static markings.

1st set of IIO new device support, features and cleanups for the 6.4 cycle.
New device support
* bosch,bmp280
- Add support for BMP580 - includes significant refactoring and general
driver cleanup + support for non-volatile memory for trimming and config
parameters.
* rohm BU27034
- New driver for this 3 channel ambient light sensor.
- New support library for devices where both integration time and
amplifier gain are configurable. In these cases a scale change
may require changing bother underlying values. This library module
provides code to help with this.
* st,accel
- Add support for IIS328DQ (ID only as compatible wtih LIS331DL)
* st,lsm6dsx
- Add support for ASM330LHB automotive MEMS sensor.
* ti,ads1100, ads1000
- New driver for these 16 bit ADCs.
* ti,tmp117
- Add support for older tmp116 device. Includes some general driver cleanup.
Staging driver drops
* adi,ade7854
- Driver was a very long way from compliant with IIO infrastructure and ABI.
If anyone wants a non staging version of this driver they are better off
starting from scratch. Hence drop it and the associated meter.h header.
Features
* adi,ad7441r
- Add DT binding to set sink current for digital input.
* semtech,sx9324,9360
- Support older register mapping from firmware designed for windows.
Core improvements.
* Move iio_trigger_poll() docs to next to the implementation and add a note
on expected caller context.
* Rename iio_trigger_poll_chained() to iio_trigger_poll_nested() so
as to use more standard / common terminology.
* Improve main ABI docs references to offset and scale for raw values by
making them consistent and clear.
Cleanups and minor fixes:
* adi,ad5592r
- Add GPIO names - useful for debug.
* adi,ad7441r
- Fix current input, loop powered mode configuration setup.
* adi,adis16475
- Fix wrong commented value for minimum advised lower rate.
* adi,admv1013
- Use devm_clk_get_enabled() to reduce boilerplate.
* adi,ads1210
- Fix wrong bits for writing config register (late fix and has
been broken a long time so not rushed upstream)
* amlogic,meson-saradc
- Improve cleanup in error handling if BL30 handshake fails.
* apex-embedded,stx104
- Migrate to regmap and use regmap_read_poll_timeout() to neatly handle
retries.
- Add local mutex to close various races.
- Use define U16_MAX rather than value for limit.
- Improve code readability with minor reorganization.
* atmel,ad91-sama5d2
- Drop trivial dead code.
* kionix,kx022a
- Drop unused structure element.
* linear,ltc2983
- Reorganize bindings doc to enable unevaluatedProperties to be set
in one place for all child nodes.
- Make binding for adi,custom-thermocouple accept signed values.
* maxim,max44000
- Add OF Device matching (of_match_table was not correctly set).
* maxim,max5522
- Missing static
* measurement-computing,cio-dac
- Fix wrong part name in comments.
- Migrate to regmap.
- Improve includes by replacing bitops.h with more direct bits.h
* qcom,pm8xxx-xoadc
- Remove a check that can never fail.
* renesas,rcar-gyroadc
- DT binding documentation improvements.
- Tidy up an unused warning with __maybe_unused.
* semtech,sx_common
- Drop docs for a structure element that doesn't exist.
* semtech,sx9500
- Drop ACPI_PTR() and of_match_ptr() protections that just complicate
the code / block some firmware registration types that would otherwise
work.
* sensiron,sps30
- Comment formatting tidy up.
* st,sensors
- Drop duplicate text in DT binding.
* st,stm32-adc
- Add some missing static markings.
* ti,ads1100
- Use correct return code in dev_err_probe() call.
* x-powers,axp20x_adc - precursor series to simplify addition of AXP192.
- General code cleanup / minor refactoring for better readabilty of code.
- Switch from boolean value to mask for adc_en2 field to avoid hard coding
a mask that will be different in AXP192

Supporting multi-cs in spi drivers would require the chip_select & cs_gpiod
members of struct spi_device to be an array. But changing the type of these
members to array would break the spi driver functionality. To make the
transition smoother introduced four new APIs to get/set the
spi->chip_select & spi->cs_gpiod and replaced all spi->chip_select and
spi->cs_gpiod references with get or set API calls.
While adding multi-cs support in further patches the chip_select & cs_gpiod
members of the spi_device structure would be converted to arrays & the
"idx" parameter of the APIs would be used as array index i.e.,
spi->chip_select[idx] & spi->cs_gpiod[idx] respectively.

During digital filters settling time the driver is expected to drop
samples since they can be corrupted. Introduce the capability to drop
a given number of samples according to the configured ODR.
Add sample_to_discard for LSM6DSM-like sensors since new generation
devices (e.g. LSM6DSO) support DRDY mask where corrupted samples are
masked in hw with values greather than 0x7ffd so the driver can easily
discard them.
I have not added sample_to_discard support for LSM6DS3 or LSM6DS3H since
I do not have any sample for testing at the moment.

+/-1200uT is a MAGN sensor full measurement range. Magnetometer scale
is the magnetic sensitivity parameter. It is referenced as 0.1uT
according to datasheet and magnetometer channel unit is Gauss in
sysfs-bus-iio documentation. Gauss and uTesla unit conversion
relationship as follows: 0.1uT = 0.001Gs.
Set magnetometer scale and available magnetometer scale as fixed 0.001Gs.
