This driver supports 14-bits and 16-bits devices. All of them have a 14-bit
configuration registers. All SPI trasfers, for reading AD conversion
results and for writing the configuration register, fit in two bytes.
The driver always uses 4-bytes xfers which seems at least pointless (maybe
even harmful). This patch trims the SPI xfer len and the buffer size to
two bytes.

The iio_triggered_buffer_{predisable,postenable} functions attach/detach
the poll functions.
For the predisable hook, the disable code should occur before detaching
the poll func, and for the postenable hook, the poll func should be
attached before the enable code.
The driver was slightly reworked. The preenable hook was moved to the
postenable, to add some symmetry to the postenable/predisable part.

The device could be configured to spit out also the configuration word
while reading the AD result value (in the same SPI xfer) - this is called
"readback" in the device datasheet.
The driver checks if readback is enabled and it eventually adjusts the SPI
xfer length and it applies proper shifts to still get the data, discarding
the configuration word.
The readback option is actually never enabled (the driver disables it), so
the said checks do not serve for any purpose.
Since enabling the readback option seems not to provide any advantage (the
driver entirely sets the configuration word without relying on any default
value), just kill the said, unused, code.

Separate the declaration of struct bh1750_chip_info from definition
of bh1750_chip_info_tbl[] in a single statement as it makes the code

The commit 473d12f7638c
("iio: hid-sensor-attributes: Convert to use int_pow()")
converted to use generic int_pow() helper. Though, the generic one returns
64-bit value and, in cases when it is used as divisor, it compels 64-bit
division from compiler.
In order to fix this, introduce a temporary 32-bit variable to hold the result
of int_pow() and use it as divisor afterwards.
In couple of cases, replace int_pow() with a predefined unit factors for time
and frequency.

Second set of new device support, cleanups and features for IIO in the 5.4 cycle
Revised pull request to fix up a missing Signed-off-by and roll in
a fix in the lsm9ds1 support after I broke it when applying.
Revised again because the fix changed a hash meaning a fix
that previously followed it now had the wrong fixes tag.
A few fixes in here that could have gone a faster path but aren't quite
worth the rush for 5.3.
New device support
* ad7606
- Support the ad7606b which adds a software controlled mode alongside
the pin controlled only approach of the ad7606. Including dt-bindings.
* lsm6dsx
- Add support for the gyro and accelerometer part of the lsm9ds1 which is
a compound device also including a magnetometer (st_sensors driver).
Includes bindings and precursor rework of the driver.
Features
* ad7192
- Add support for low pass filter control.
- DT binding docs.
Cleanups and minor fixes
* MAINTAINERS
- Fix a typo in a path.
- Add entry for ad7606
* ad5380
- Fix a failure to dereference a pointer before atempting to assign the
value.
* ad7192
- Drop platform data as not used in mainline and we now have full DT bindings.
* ad7606
- YAML conversion for dt-bindings.
* adis16240
- Rework write_raw to make it more readable using GENMASK.
* adis16460
- Fix and issue with an unsigned variable holding potential negatives.
* cros_ec
- Fix missing default of calibration vector so that we get 'something'
before calibration is complete on a given axis.
* hid-sensors
- Use int_pow instead of opencoding.
* isl29501
- rename dt-binding docs to include renesas inline with other renesas parts
and general current convention.
* kxcjk1013
- Improve comments on the 'unusual' ACPI ids used to identify which sensor
is which in certain laptops.
* lsm6dsx
- Add one bit to the fifo status masks for a number of parts.
- Drop a reserved entry from the sensitivity values to tidy up interface.
- Use core conversion macro from G to m/s^2 for lsm9ds1 to make it easier
to relate to the datasheet and consistent with other parts supported.
* max1027
- Use device managed APIs to avoid manual error handling and cleanup.
* rfd77402
- Typo in Kconfig help.
* sc27xx
- Switch to polling mode from interrupts as interrupt handling typically
to slow for very short sleeps.
* st-sensors
- Fix some missing selects for regmap.
* tools
- Add a .gitignore containing the binary outputs.

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.

There is a bit of mess between cros-ec mfd includes and platform
includes. For example, we have a linux/mfd/cros_ec.h include that
exports the interface implemented in platform/chrome/cros_ec_proto.c. Or
we have a linux/mfd/cros_ec_commands.h file that is non related to the
multifunction device (in the sense that is not exporting any function of
the mfd device). This causes crossed includes between mfd and
platform/chrome subsystems and makes the code difficult to read, apart
from creating 'curious' situations where a platform/chrome driver includes
a linux/mfd/cros_ec.h file just to get the exported functions that are
implemented in another platform/chrome driver.
In order to have a better separation on what the cros-ec multifunction
driver does and what the cros-ec core provides move and rework the
affected includes doing:
- Move cros_ec_commands.h to include/linux/platform_data/cros_ec_commands.h
- Get rid of the parts that are implemented in the platform/chrome/cros_ec_proto.c
driver from include/linux/mfd/cros_ec.h to a new file
include/linux/platform_data/cros_ec_proto.h
- Update all the drivers with the new includes, so
- Drivers that only need to know about the protocol include
- linux/platform_data/cros_ec_proto.h
- linux/platform_data/cros_ec_commands.h
- Drivers that need to know about the cros-ec mfd device also include
- linux/mfd/cros_ec.h

Move some register definitions to the per-device array of struct
st_lsm6dsx_sensor_settings in order to simplify adding new sensor
devices to the driver.
Also, remove completely unused register definitions.

The AD7606B is a 16-bit ADC that supports simultaneous sampling of 8
channels. It is pin compatible to AD7606, but adds extra modes by
writing to the register map.
The AD7606B can be configured to work in software mode by setting all
oversampling pins to high. This mode is selected by default.
The oversampling ratio is configured from the OS_MODE register (address
0x08) with the addition of OS=128 and OS=256 that were not available in
hardware mode.
The device is configured to output data on a single spi channel, but this
configuration must be done right after restart. That is why the delay was
removed for devices which doesn't require it.
Moreover, in software mode, the range gpio has no longer its function.
Instead, the scale can be configured individually for each channel from
the RANGE_CH registers (address 0x03 to 0x06). Besides the already
supported ±10 V and ±5 V ranges, software mode can also accommodate the
±2.5 V range.

On Spreadtrum platform, the headphone will read one ADC channel multiple
times to identify the headphone type, and the headphone identification is
sensitive of the ADC reading time. And we found it will take longer time
to reading ADC data by using interrupt mode comparing with the polling
mode, thus we should change to polling mode to improve the efficiency
of reading data, which can identify the headphone type successfully.

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 {
154 struct adis16460 *st = iio_priv(indio_dev);
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.

The KIOX010A and KIOX020A ACPI ids go hand in hand, they are used in
yoga style 2-in-1s, with KIOX010A indicating the KXCJ91008 sensor in the
display of the 2-in-1 and KIOX020A indicating the KXCJ91008 sensor in the
base.
Improve the existing comment on the "KIOX010A" kx_acpi_match table entry
to make clear we are talking about a yoga-style (360 degree hinges) device
here and add a similar comment to the "KIOX020A" entry.

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.
