One in two sample sets was lost by multiplying fifo_set_size with
sizeof(u16). Also, the double number of available samples were pushed to
the iio buffers.

Currently, the driver sets the FIFO_SAMPLES register with the number of
sample sets (maximum of 170 for 3 axis data, 256 for 2-axis and 512 for
single axis). However, the FIFO_SAMPLES register should store the number
of samples, regardless of how the FIFO format is configured.

Fix bug in sampling function hx711_cycle() when interrupt occures while
PD_SCK is high. If PD_SCK is high for at least 60 us power down mode of
the sensor is entered which in turn leads to a wrong measurement.
Switch off interrupts during a PD_SCK high period and move query of DOUT
to the latest point of time which is at the end of PD_SCK low period.
This bug exists in the driver since it's initial addition. The more
interrupts on the system the higher is the probability that it happens.

The center temperature of the supported devices stored in the constant
BMC150_ACCEL_TEMP_CENTER_VAL is not 24 degrees but 23 degrees.
It seems that some datasheets were inconsistent on this value leading
to the error. For most usecases will only make minor difference so
not queued for stable.

meson_saradc's irq handler uses priv->regmap so make sure that it is
allocated before the irq get enabled.
This also fixes crash when CONFIG_DEBUG_SHIRQ is enabled, as device
managed resources are freed in the inverted order they had been
allocated, priv->regmap was freed before the spurious fake irq that
CONFIG_DEBUG_SHIRQ adds called the handler.

The variable n is being assigned a value that is never read inside
an if statement block, the assignment is redundant and can be removed.
With this removed, n is only being used for a constant loop bounds

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.
* tag 'iio-for-5.4b-take3' of git://git.kernel.org/pub/scm/linux/kernel/git/jic23/iio: (27 commits)

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.

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.

By adding this option we are able to remove the sync3 field and dt binding.
When setting the required cutoff frequency we also determine the ADC
configuration for chop and sync filter.

This patch removes the reference voltage entry from the platform_data
structure. This is no longer needed since the reference voltage is obtained
from the device tree. With this we also remove the entire ad7192.h file.
The undefined reference voltage warning is promoted to an error signaling a
problem with the device tree.

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.

Currently, __inline is #defined as inline in compiler_types.h, so this
should not change functionality. It is preparation for removing said
#define.
While at it, change some "inline static" to the customary "static
inline" order.

A call to FAT_getblk is missing a null return check which can
lead to a null pointer dereference. Fix this by adding a null
check to match all the other FAT_getblk return sanity checks.

The problem is in gb_lights_request_handler(). If we get a request to
change the config then we release the light with gb_lights_light_release()
and re-allocated it. However, if the allocation fails part way through
then we call gb_lights_light_release() again. This can lead to a couple
different double frees where we haven't cleared out the original values:
gb_lights_light_v4l2_unregister(light);
...
kfree(light->channels);
kfree(light->name);
I also made a small change to how we set "light->channels_count = 0;".
The original code handled this part fine and did not cause a use after
free but it was sort of complicated to read.
