Yiyuan Guo 8a4629055e iio: cros_ec: Fix the allocation size for cros_ec_command
The struct cros_ec_command contains several integer fields and a
trailing array. An allocation size neglecting the integer fields can
lead to buffer overrun.

George Stark 09738ccbc4 iio: adc: meson: fix core clock enable/disable moment
Enable core clock at probe stage and disable it at remove stage.
Core clock is responsible for turning on/off the entire SoC module so
it should be on before the first module register is touched and be off
at very last moment.

Milan Zamazal b2a6996990 iio: core: Prevent invalid memory access when there is no parent
Commit 813665564b ("iio: core: Convert to use firmware node handle
instead of OF node") switched the kind of nodes to use for label
retrieval in device registration.  Probably an unwanted change in that
commit was that if the device has no parent then NULL pointer is
accessed.  This is what happens in the stock IIO dummy driver when a
new entry is created in configfs:

  # mkdir /sys/kernel/config/iio/devices/dummy/foo
  BUG: kernel NULL pointer dereference, address: ...
  ...
  Call Trace:
  __iio_device_register
  iio_dummy_probe

Since there seems to be no reason to make a parent device of an IIO
dummy device mandatory, let’s prevent the invalid memory access in
__iio_device_register when the parent device is NULL.  With this
change, the IIO dummy driver works fine with configfs.

Dan Carpenter 507397d19b iio: frequency: admv1013: propagate errors from regulator_get_voltage()
The regulator_get_voltage() function returns negative error codes.
This function saves it to an unsigned int and then does some range
checking and, since the error code falls outside the correct range,
it returns -EINVAL.

Beyond the messiness, this is bad because the regulator_get_voltage()
function can return -EPROBE_DEFER and it's important to propagate that
back properly so it can be handled.

Alvin Šipraga a41e19cc0d iio: adc: ina2xx: avoid NULL pointer dereference on OF device match
The affected lines were resulting in a NULL pointer dereference on our
platform because the device tree contained the following list of
compatible strings:

    power-sensor@40 {
        compatible = "ti,ina232", "ti,ina231";
        ...
    };

Since the driver doesn't declare a compatible string "ti,ina232", the OF
matching succeeds on "ti,ina231". But the I2C device ID info is
populated via the first compatible string, cf. modalias population in
of_i2c_get_board_info(). Since there is no "ina232" entry in the legacy
I2C device ID table either, the struct i2c_device_id *id pointer in the
probe function is NULL.

Fix this by using the already populated type variable instead, which
points to the proper driver data. Since the name is also wanted, add a
generic one to the ina2xx_config table.

Matti Vaittinen 096649cd7c iio: light: bu27008: Fix scale format
The driver is expecting accuracy of NANOs for intensity scale in
raw_write. The IIO core is however defaulting to MICROs. This leads the
raw-write of smallest scales to never succeed as correct selector(s) are
not found.

Fix this by implementing the .write_raw_get_fmt callback to use NANO
accuracy for writes of IIO_CHAN_INFO_SCALE.

Greg Kroah-Hartman 269b9d8faf 1st set of IIO new device support, features and cleanup for the 6.5 cycle.
New device support
 - honeywell,mprls0025pa
   * New driver and dt-bindings for this series of pressure sensors.
 - invensense,mpu6050
   * Add support for ICM 20600 IMU (ID, bindings and device data).
 - melexis,mlx90614
   * Add support for mlx90615 Infra Red Thermometer after driver cleanup
     and refactoring to support the differences in this device.
 - renesas,x9250
   * New driver and bindings for this quad potentiometer.
 - rockchip,saradc
   * Add support for RK3588. Also included is a bunch of refactoring and
     cleanup for that driver.
 - rohm,bu27008
   * New driver bindings etc for this 5 photodiode color sensor.
 - st,lsm9ds0/st,st-sensors
   * ID added for LSM303D accelerometer and magnetometer including ACPI binding.
 - ti,opt4001
   * New driver and bindings for this ambient light sensor.
 
 Features
 - core
   * Introduce iio_validate_own_trigger() for cases where a driver can only
     consumer a trigger it registered (detected via same parent device).
     Use it in the kionix,kx022a driver and new rohm,by27008 driver.
 - dynaimage,al3320a
   * ACPI binding CALS0001 seen on Lenovo Yoga Table 2 devices.
 - kionix,kx002a
   * Enable asynchronous probe.
 - rohm,bu27034
   * Enable asynchronous probe.
 - ti,tmp006
   * Explicit support for DT including binding documentation.
 
 Cleanups, minor fixes and misc improvements.
 - treewide
   * Switch I2C drivers from probe_new() back to probe() - part of the
     long process of getting rid of a parameter from probe()
   * Various whitespace and typo fixes not otherwise called out.
 - core
   * industrialio-buffer,Style cleanup.
   * Add documentation to extend_name field of struct iio_chan_spec to
     direct people using it towards the label infrastructure instead.
     extend_name was a design mistake a long time back so directly people
     away from it may be useful.
 - adi,ad7606

Rasmus Villemoes a4cba07e64 iio: addac: ad74413: don't set DIN_SINK for functions other than digital input
Apparently, despite the name Digital Input Configuration Register, the
settings in the DIN_CONFIGx registers also affect other channel
functions. In particular, setting a non-zero value in the DIN_SINK
field breaks the resistance measurement function.

Now, one can of course argue that specifying a drive-strength-microamp
property along with a adi,ch-func which is not one of the digital
input functions is a bug in the device tree. However, we have a rather
complicated setup with instances of ad74412r on external hardware
modules, and have set a default drive-strength-microamp in our DT
fragments describing those, merely modifying the adi,ch-func settings
to reflect however the modules have been wired up. And restricting
this setting to just being done for digital input doesn't make the
driver any more complex.

Jean-Baptiste Maneyrol f3ae82534a iio: imu: inv_icm42600: avoid frequent timestamp jitter
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.

Marek Vasut 7699e975e5 iio: mlx90614: Add MLX90615 support
Add support for MLX90615 Infra Red Thermometer, which seems to be
the predecesor of MLX90614 . There are significant differences in
the register layout compared to MLX90614, but the functionality
of the device is virtually identical.

The following differences have been identified:
- RAM/EEPROM/SLEEP access opcodes are different
- RAM/EEPROM registers are at different offsets
- EEPROM emissivity and configuration registers are at different offsets
- EEPROM configuration register bits are shuffled around
- EEPROM emissivity settings are 14 bit on MLX90615 , 16 bit on MLX90614
- MLX90615 can only ever support one sensor, MLX90614 could support two
- FIR filter is set to fixed settings on MLX90615
- IIR filter coefficients are different

This patch fills in the MLX90615 specific description and quirk handling.

The IIR filter coefficients were provided by Melexis as follows:
0b0000 - Forbidden value
0b0001 - 100% - settling time = refresh rate = 205ms (around 5Hz)
0b0010 - 50% - settling time = 2050ms (around 0.5Hz)
0b0011 - 33% - settling time = 36900ms (around 0.3Hz)
0b0100 - 25% - settling time = 5125ms (around 0.2Hz)
0b0101 - 20% - settling time = 6355ms (around 0.15Hz)
0b0110 - 17% - settling time = 7790ms (around 0.13Hz)

Jean-Baptiste Maneyrol bbaae0c79e iio: imu: inv_icm42600: fix timestamp reset
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.

Masahiro Honda 626d312028 iio: adc: ad_sigma_delta: Fix IRQ issue by setting IRQ_DISABLE_UNLAZY flag
The Sigma-Delta ADCs supported by this driver can use SDO as an interrupt
line to indicate the completion of a conversion. However, some devices
cannot properly detect the completion of a conversion by an interrupt.
This is for the reason mentioned in the following commit.

commit e9849777d0 ("genirq: Add flag to force mask in
                      disable_irq[_nosync]()")

A read operation is performed by an extra interrupt before the completion
of a conversion. At this time, the value read from the ADC data register
is the same as the previous conversion result. This patch fixes the issue
by setting IRQ_DISABLE_UNLAZY flag.

Matti Vaittinen 56cd3d1c5c iio: accel: kx022a fix irq getting
The fwnode_irq_get_byname() was returning 0 at device-tree mapping
error. If this occurred, the KX022A driver did abort the probe but
errorneously directly returned the return value from
fwnode_irq_get_byname() from probe. In case of a device-tree mapping
error this indicated success.

The fwnode_irq_get_byname() has since been fixed to not return zero on
error so the check for fwnode_irq_get_byname() can be relaxed to only
treat negative values as errors. This will also do decent fix even when
backported to branches where fwnode_irq_get_byname() can still return
zero on error because KX022A probe should later fail at IRQ requesting
and a prober error handling should follow.

Relax the return value check for fwnode_irq_get_byname() to only treat
negative values as errors.

Matti Vaittinen d049151add iio: bu27034: Ensure reset is written
The reset bit must be always written to the hardware no matter what value
is in a cache or register. Ensure this by using regmap_write_bits()
instead of the regmap_update_bits(). Furthermore, the SWRESET bit may be
self-clearing, so mark the SYSTEM_CONTROL register volatile to guarantee
we do also read the right state - should we ever need to read it.

Finally, writing the SWRESET bit will restore the default register
values. This can cause register cache to be outdated if there are any
register values cached.

Rebuild register cache after SWRESET and use regmap_update_bits() when
performing the reset.

Lukas Bulwahn a146eccb68 iio: dac: build ad5758 driver when AD5758 is selected
Commit 28d1a7ac2a ("iio: dac: Add AD5758 support") adds the config AD5758
and the corresponding driver ad5758.c. In the Makefile, the ad5758 driver
is however included when AD5755 is selected, not when AD5758 is selected.

Probably, this was simply a mistake that happened by copy-and-paste and
forgetting to adjust the actual line. Surprisingly, no one has ever noticed
that this driver is actually only included when AD5755 is selected and that
the config AD5758 has actually no effect on the build.
