Since the logic for `spi_delay` struct + `spi_delay_exec()` has been copied
from the `cs_change_delay` logic, it's natural to make this delay, the
first user.
The `cs_change_delay` logic requires that the default remain 10 uS, in case
it is unspecified/unconfigured. So, there is some special handling needed
to do that.
The ADIS library is one of the few users of the new `cs_change_delay`
parameter for an spi_transfer.
The introduction of the `spi_delay` struct, requires that the users of of
`cs_change_delay` get an update. This change also updates the ADIS library.

It could happen that either `val` or `val2` [provided from userspace] is
negative. In that case the computed frequency could get a weird value.
Fix this by checking that neither of the 2 variables is negative, and check
that the computed result is not-zero.

The LSM9DS1's accelerometer / gyroscope unit and it's magnetometer (separately
supported in iio/magnetometer/st_magn*) are located on a separate i2c addresses
on the bus.
For the datasheet, see https://www.st.com/resource/en/datasheet/lsm9ds1.pdf
Treat it just like the LSM6* devices and, despite it's name, hook it up
to the st_lsm6dsx driver, using it's basic functionality.
accelerometer and gyroscope are not independently clocked. It runs at the gyro
frequencies if both are enabled, see chapter 7.12 of the datasheet.
We could have handled this as a single IIO device but we have split
it up to be more consistent with the other more flexible devices.
Despite supporting and testing the LSM9DS1, we call the gyro channels
iio_chan_spec struct "st_lsm6ds0_gyro_channels" because the register
description is equal. This suggests that supporting LSM6DS0 should be
trivial to do.

Caught via static-analysis checker:
```
drivers/iio/imu/adis16460.c
152 static int adis16460_set_freq(struct iio_dev *indio_dev, int val, int val2)
153 {

155 unsigned int t;
^^^^^^^^^^^^^^
156
157 t = val * 1000 + val2 / 1000;
158 if (t <= 0)
^^^^^^
Unsigned is not less than zero.
```
The types of `val` && `val2` are obtained from the IIO `write_raw` hook, so
userspace can provide negative values, which can cause weird behavior after
conversion to unsigned.
This patch changes the sign of variable `t` so that -EINVAL will be
returned for negative values as well.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
First set of new device support, features and cleanups for IIO in the 5.4 cycle
Note includes a merge from i3c tree to get support needed for stm_lsm6dsx driver
support for l3c devices. Done from immutable branch.
A counter subsystem patche in here as well.
Alongside the new device support (which is always good), Chuhong's work
on using devres managed APIs has cleaned up a number of drivers.
New device support
* adis16460
- New driver based on ADIS framework which needed addition of support
for cs_change_delay. Includes device tree binding.
* cros_ec
- Support fo the veyron-minnie which uses an older interface.
* lsm6dsx
- Support for LSM6DSTR-C gyro + magnetometer sensor (new IDs mainly)
- Support for ISM330DHCX acc + gyro sensor (extensive rework needed!)
* Maxim 5432
- New driver support MAX5432-MAX5435 family of potentiometers.
* noa1305
- New driver for this ON Semiconductor Ambient light sensor.
Features and cleanups
* tree wide
- Drop error prints after platform_get_irq as already prints errors
internally if any occur.
* docs
- Document mounting matrix.
- Fix a missing newline at end of file.
* ad2s1210
- Switch to device managed APIs for all of probe and drop explicit remove.
* ad7192
- Add of_device_id array to explicity handling DT bindings.
* ad7606
- Lots of rework leading to support for software configure modes in ad7616
parts.
- Debugfs register access support.
* am2315
- Switch to device managed APIs for all of probe and drop explicit remove.
* apds9960
- Typo in module description.
* cm36651
- Convert to i2c_new_dummy_device.
- Swithc to device managed APIs for all of probe adn drop explicit remove.
* cros_ec
- Calibscale support for accel, gyro and magnetometer.
- Tidy up some error codes to return the error from the stack rather than
-EIO.
- Determine protocol version.
- Add a sign vector to the core to fix sensor rotation if necessary.
Cannot just be done with mount matrix as already in use in many devices.
- Tidy up INFO_SCALE being in both the separate and shared lists.
- Drop a lot of dplicate code from the cros-ec-accel-legacy driver
and use the core provided code instead.
- Make frequency range available to userspace.
* counter / ftm-quaddec
- Switch to device managed APIs for all of probe adn drop explicit remove.
* hdc100x
- Switch to device managed APIs for all of probe and drop explicit remove.
* hi8435
- Use gpiod_set_value_cansleep as we don't care here and there is a
board out there where it needs to sleep.
- Switch to device managed APIs for all of probe and drop explict remove.
* hp03
- Convert to i2c_new_dummy_device.
* maxim thermocouple
- Switch to device managed APIs for all of probe and drop explicit remove.
* mmc35240
- Fix typo in constant naming.
* mpu6050
- Use devm_add_action_or_reset in place of explicit error handling.
- Make text in Kconfig more explicit about which parts are supported.
* mxc4005
- Switch to device managed APIs for all of probe and drop explicit remove.
* pms7003
- Convert device tree bindings to yaml.
- Add a MAINTAINERS entry
* sc27xx
- Introduce a local struct device *dev pointer to avoid lots of deref.
- Use devm_add_action_or_reset in place of explicit error handling.
* sca3000
- Typo fix in naming.
* si1145
- Switch to device managed APIs for all of probe and drop explicit remove.
* st_sensors
- Lots of rework to enable switch to regmap.
- Regmap conversion at the end.
- Tidy up some inconsistencies in buffer setup ops.
- Tidy up an oddity by dropping get_irq_data_ready function in favour
of direct access.
- Stop allocating buffer in buffer enable in favour of just embedding
a large enough constant size buffer in the iio_priv accessed structure.
* st_lsm6dsx
- l3c device support (LSM6DSO and LSM6DSR)
- tidy up irq return logic which was strangely written.
- fix up an ABI quirk where this driver used separate scale
attributes, even though they were always shared by type.
* stk33xx
- Device tree bindings include manufacturer ID.
* stm32-adc
- Add control for supply to analog switches including DT bindings.
* stm32 timer
- Drop the quadrature mode support. Believed there were no users so
take this opportunity to drop this unwanted ABI.
* tsl2772
- Switch to device mangage APIs for all of probe and drop explicit remove.
- Use regulator_bulk_* APIs to reduce repitition.
* veml6070
- Convert to i2c_new_dummy_device.

in_accel_x_scale, in_accel_y_scale and in_accel_z_scale are always
the same. The scale is still defined to be in "info_mask_separate".
Userspace (iio-sensor-proxy and others) is not used to that and only
looks for "in_accel_scale" for the scaling factor to apply.
Change IIO_CHAN_INFO_SCALE from being separate in all channel to be
shared by type.
This removes in_accel_x_scale, in_accel_y_scale and in_accel_z_scale and
makes available in_accel_scale.
This is an ABI change, but hopefully in the 'no one will notice'
category. The cleanup in interface is worth the small risk that
there is a custom script out there somewhere that this will break.

The ADIS16460 device is a complete inertial system that includes a triaxial
gyroscope and a triaxial accelerometer. It's more simplified design than
that of the ADIS16480, and does not offer the triaxial magnetometers &
pressure sensors. It does also have a temperature sensor (like the
ADIS16480).
Since it is part of the ADIS16XXX family, it re-uses parts of the ADIS
library.
Naturally, the register map is different and much more simplified than the
ADIS16480 subfamily, so it cannot be integrated into that driver. A major
difference is that the registers are not paged.
One thing that is particularly special about it, is that it requires a
higher delay between CS changes (i.e. when CS goes up, the spec recommends
that it be brought down after a minimum of 16 uS).
Other ADIS chips require (via spec) a minimum of 2 uS between CS changes.
The kernel's 10 uS default should be fine for those other chips; they
haven't been tested with lower CS change delays yet.

The ADIS16460 requires a higher delay before the next transfer. Since the
SPI framework supports configuring the delay before the next transfer, this
driver will become the first user of it.
The support for this functionality in ADIS16460 requires an addition to the
ADIS lib to support the `cs_change_delay` functionality from the SPI
subsystem.

devm_add_action_or_reset()
devm_add_action_or_reset() is introduced as a helper function which
internally calls devm_add_action(). If devm_add_action() fails
then it will execute the action mentioned and return the error code.
This reduce source code size (avoid writing the action twice)
and reduce the likelyhood of bugs.

Driver only supports 3-axis gyro and/or 3-axis accel.
For icm20602, temp data is mandatory for all configurations.
Fix all single and double axis configurations (almost never used) and more
importantly fix 3-axis gyro and 6-axis accel+gyro buffer on icm20602 when
temp data is not enabled.

git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio into staging-next
Jonathan writes:
Second set of IIO device support, features, cleanups and minor fixes for 5.3.
A few bits for the counters subsystem mixed in here as well.
There are some late breaking fixes as well, which aren't so urgent
they can't wait for the merge window.
New Device Support
* adf4371
- New driver + bindings.
- Support the adf4372 PLL. Mostly ID and bindings.
* ad8366 (note includes rework of driver needed to allow support for these).
- Support the ADL5240 variable gain amplifier (VGA).
- Support the ADA4961 digital gain amplifier (DGA).
* dps310
- New driver, in several parts from different authors for this temp
and pressure sensor.
- Includes errata workaround for a temperature reading issue.
* stk3310
- Support the stk3335, mostly ID.
Features and cleanups
* core
- drop error handling on debugfs registration.
- harden by making sure we don't overrun iio_chan_info_postfix.
* docs
- convert remaining docs to rst. At somepoint we'll fit these few
into the main IIO docs.
- improve sampling_frequency_available docs but explaining the
range form.
* ad_sigma_delta
- Drop a pointless goto.
* ad2s1210
- Drop pointless platform data null check seeing as we don't actually
use platform data anymore.
* ad7124
- Relax limitation on channel numbers to allow pseudo different channels.
- Support control of whether the input is buffered via DT.
- Use dynamic allocation for channel configuration to make it easier
to support new devices.
- YAML binding conversion.
* ad7150
- Comment tidy up.
- Consistent and simple if (ret) handling of i2c errors.
- FIELD_GET and GENMASK.
- Ternary rather than !!(condition) for readability.
- Use macros to avoid repetition of channel definitions.
* ad7606
- Add software channel config (rather that pin controlled)
- Refactor to simplify addition of new part in future.
* ad7746
- of_deivce_id table.
* ad7780
- MAINTAINERS entry
- YAML DT bindings.
* ad8366
- Stop using core mlock in favour of well scoped local lock.
- SPDX + copyright date update.
* ad9834
- of_device_id table
* adf4371
- Add support for output stage muting before lock on has occured.
* adis library
- MAINTAINERS entry to reflect that this now Alexandru's problem ;)
* adis162xx:
- Fix a slightly incorrect set of comments and print statements on
minimum supported voltage.
* adis16203
- of_device_id table.
* adis16240
- Add of_device_id table (in two parts as first patch only used it for
MODULE_DEVICE_TABLE.)
* adt7316-spi
- of_device_id table
* adxl372
- YAML DT binding conversion.
- Cleanup use of buffer callback functions (precursor to core rework).
* bh1710
- Simplify getting the i2c adapter from the client.
* dht11
- Mote to newer GPIO consumer interface.
* kxcjk-1013.c
- Add binding for sensor in display of some ultrabooks after userspace
tools updated for it not be a problem to report two similar sensors.
* imx7d
- drop unused variables.
- white space
- define instead of variable for clock frequency that is fixed.
- drop pointless error message.
* messon_saradc
- SPDX
* sps30
- MAINTAINERS entry
- YAML binding conversion.
* st_accel
- Tidy up ordering in various buffer related callbacks. This is
part of a long running effort to simplify the core code.
* stm32-dfsdm:
- Manage the resolution cleanly in triggerd modes.
- Add fast mode support which allows more flexible filter choices.
- Add a comment on the reason for a 16 bit record when technically
not 'required'.
* st_lsm6dsx
- Embed device name in the sensor_settings struct as i3c doesn't
have a convenient name field to use for this.
* xilinx-adc
- Relax constraints on supported platforms to reflect that this
can used with FPGAs on PCIe cards and hence many architectures.
* counters/ftm-quaddec
- Fix some formatting io MODULE_AUTHOR
- MAINTAINERS entry
Fixes
* tools
- fix incorrect handling of 32 bit channels.
* sca3000
- Potential endian bug that is unlikely to bite anyone (be64 host
seems unlikely for this old part).
* stm32-adc
- Add vdda-supply. On some boards it needs to be turned on to supply
the ADC. DT bindings included.
* stm32-dfsdm
- Fix output resolution to work with filter orders other than 3.
- Fix output datatype as it's signed and previously claimed not to be.

Pull staging/IIO/counter fixes from Greg KH:
"Here are some small driver bugfixes for some staging/iio/counter
drivers.
Staging and IIO have been lumped together for a while, as those
subsystems cross the areas a log, and counter is used by IIO, so
that's why they are all in one pull request here.
These are small fixes for reported issues in some iio drivers, the
erofs filesystem, and a build issue for counter code.
All have been in linux-next with no reported issues"
