d11f14a791 iio: invensense: fix multiple odr switch when FIFO is off
commit ef5f5e7b6f upstream.

When multiple ODR switch happens during FIFO off, the change could
not be taken into account if you get back to previous FIFO on value.
For example, if you run sensor buffer at 50Hz, stop, change to
200Hz, then back to 50Hz and restart buffer, data will be timestamped
at 200Hz. This due to testing against mult and not new_mult.

To prevent this, let's just run apply_odr automatically when FIFO is
off. It will also simplify driver code.

Update inv_mpu6050 and inv_icm42600 to delete now useless apply_odr.

67e972130b iio: magnetometer: yas530: use signed integer type for clamp limits
[ Upstream commit f1ee5483e4 ]

In the function yas537_measure() there is a clamp_val() with limits of
-BIT(13) and BIT(13) - 1.  The input clamp value h[] is of type s32.  The
BIT() is of type unsigned long integer due to its define in
include/vdso/bits.h.  The lower limit -BIT(13) is recognized as -8192 but
expressed as an unsigned long integer.  The size of an unsigned long
integer differs between 32-bit and 64-bit architectures.  Converting this
to type s32 may lead to undesired behavior.

Additionally, in the calculation lines h[0], h[1] and h[2] the unsigned
long integer divisor BIT(13) causes an unsigned division, shifting the
left-hand side of the equation back and forth, possibly ending up in large
positive values instead of negative values on 32-bit architectures.

To solve those two issues, declare a signed integer with a value of
BIT(13).

There is another omission in the clamp line: clamp_val() returns a value
and it's going nowhere here.  Self-assign it to h[i] to make use of the
clamp macro.

Finally, replace clamp_val() macro by clamp() because after changing the
limits from type unsigned long integer to signed integer it's fine that
way.

1bdff8a19c iio: gts: fix infinite loop for gain_to_scaletables()
commit 7452f8a081 upstream.

In iio_gts_build_avail_time_table(), it is checked that gts->num_itime is
non-zero, but gts->num_itime is not checked in gain_to_scaletables(). The
variable time_idx is initialized as gts->num_itime - 1. This implies that
time_idx might initially be set to -1 (0 - 1 = -1). Consequently, using
while (time_idx--) could lead to an infinite loop.

8e5e63d6ca iio: accel: kx022a: Fix raw read format
commit b7d2bc99b3 upstream.

The KX022A provides the accelerometer data in two subsequent registers.
The registers are laid out so that the value obtained via bulk-read of
these registers can be interpreted as signed 16-bit little endian value.
The read value is converted to cpu_endianes and stored into 32bit integer.
The le16_to_cpu() casts value to unsigned 16-bit value, and when this is
assigned to 32-bit integer the resulting value will always be positive.

This has not been a problem to users (at least not all users) of the sysfs
interface, who know the data format based on the scan info and who have
converted the read value back to 16-bit signed value. This isn't
compliant with the ABI however.

This, however, will be a problem for those who use the in-kernel
interfaces, especially the iio_read_channel_processed_scale().

The iio_read_channel_processed_scale() performs multiplications to the
returned (always positive) raw value, which will cause strange results
when the data from the sensor has been negative.

Fix the read_raw format by casting the result of the le_to_cpu() to
signed 16-bit value before assigning it to the integer. This will make
the negative readings to be correctly reported as negative.

This fix will be visible to users by changing values returned via sysfs
to appear in correct (negative) format.

1a797936d3 iio: light: veml6030: fix microlux value calculation
commit 63dd163cd6 upstream.

The raw value conversion to obtain a measurement in lux as
INT_PLUS_MICRO does not calculate the decimal part properly to display
it as micro (in this case microlux). It only calculates the module to
obtain the decimal part from a resolution that is 10000 times the
provided in the datasheet (0.5376 lux/cnt for the veml6030). The
resulting value must still be multiplied by 100 to make it micro.

This bug was introduced with the original implementation of the driver.

Only the illuminance channel is fixed becuase the scale is non sensical
for the intensity channels anyway.

de1f0ab139 iio: accel: bma400: Fix uninitialized variable field_value in tap event handling.
[ Upstream commit db9795a43d ]

In the current implementation, the local variable field_value is used
without prior initialization, which may lead to reading uninitialized
memory. Specifically, in the macro set_mask_bits, the initial
(potentially uninitialized) value of the buffer is copied into old__,
and a mask is applied to calculate new__. A similar issue was resolved in
commit 6ee2a7058f ("iio: accel: bma400: Fix smatch warning based on use
of unintialized value.").

Found by Linux Verification Center (linuxtesting.org) with SVACE.

7f06b154ff iio: light: opt3001: add missing full-scale range value
commit 530688e39c upstream.

The opt3001 driver uses predetermined full-scale range values to
determine what exponent to use for event trigger threshold values.
The problem is that one of the values specified in the datasheet is
missing from the implementation. This causes larger values to be
scaled down to an incorrect exponent, effectively reducing the
maximum settable threshold value by a factor of 2.

Add missing full-scale range array value.

2cbb41abae iio: light: veml6030: fix IIO device retrieval from embedded device
commit c7c44e5775 upstream.

The dev pointer that is received as an argument in the
in_illuminance_period_available_show function references the device
embedded in the IIO device, not in the i2c client.

dev_to_iio_dev() must be used to accessthe right data. The current
implementation leads to a segmentation fault on every attempt to read
the attribute because indio_dev gets a NULL assignment.

This bug has been present since the first appearance of the driver,
apparently since the last version (V6) before getting applied. A
constant attribute was used until then, and the last modifications might
have not been tested again.

2bc96d4ea9 iio: chemical: bme680: Fix read/write ops to device by adding mutexes
[ Upstream commit 77641e5a47 ]

Add mutexes in the {read/write}_raw() functions of the device to guard the
read/write of data from/to the device. This is necessary because for any
operation other than temperature, multiple reads need to take place from
the device. Even though regmap has a locking by itself, it won't protect us
from multiple applications trying to read at the same time temperature and
pressure since the pressure reading includes an internal temperature
reading and there is nothing to ensure that this temperature+pressure
reading will happen sequentially without any other operation interfering
in the meantime.

0f115888ea iio: adc: ad7606: fix standby gpio state to match the documentation
[ Upstream commit 059fe4f8bb ]

The binding's documentation specifies that "As the line is active low, it
should be marked GPIO_ACTIVE_LOW". However, in the driver, it was handled
the opposite way. This commit sets the driver's behaviour in sync with the
documentation

4861770740 iio: adc: ad7606: fix oversampling gpio array
[ Upstream commit 8dc4594b54 ]

gpiod_set_array_value was misused here: the implementation relied on the
assumption that an unsigned long was required for each gpio, while the
function expects a bit array stored in "as much unsigned long as needed
for storing one bit per GPIO", i.e it is using a bit field.

This leaded to incorrect parameter passed to gpiod_set_array_value, that
would set 1 value instead of 3.
It also prevents to select the software mode correctly for the AD7606B.

f7dc14df1b iio: adc: ad7124: fix DT configuration parsing
[ Upstream commit 61cbfb5368 ]

The cfg pointer is set before reading the channel number that the
configuration should point to. This causes configurations to be shifted
by one channel.
For example setting bipolar to the first channel defined in the DT will
cause bipolar mode to be active on the second defined channel.

Fix by moving the cfg pointer setting after reading the channel number.
