Introduce the capability to disable sensorhub through a device-tree
property since there are some configurations where users want to
explicitly disable sensor-hub auto-probing at bootstrap.
A typical configuration is when the sensorhub clock/data lines are connected
to a pull-up resistor since no slave sensors are connected to the i2c master.
If SDO/SA0 line is connected to the same pull-up resistor, when the driver
tries to probe slave devices connected on sensor-hub, it will force SDO/SA0
line to low, modifying the device i2c address.

The length of hw->settings->odr_table is 2 and ref_sensor->id is an enum
variable whose value is between 0 and 5.
However, the value ST_LSM6DSX_ID_MAX (i.e. 5) is not caught properly in
switch (sensor->id) {
If ref_sensor->id is ST_LSM6DSX_ID_MAX, an array overflow will ocurrs in
function st_lsm6dsx_check_odr():
odr_table = &sensor->hw->settings->odr_table[sensor->id];
and in function st_lsm6dsx_set_odr():
reg = &hw->settings->odr_table[ref_sensor->id].reg;
To avoid this array overflow, handle ST_LSM6DSX_ID_GYRO explicitly and
return -EINVAL for the default case.
The enum value ST_LSM6DSX_ID_MAX is only present as an easy way to check
the limit and as such is never used, however this is not locally obvious.

All drivers that already call devm_iio_kfifo_allocate() &
iio_device_attach_buffer() are simple to convert to
iio_device_attach_kfifo_buffer() in a single go.
This change does that; the unwind order is preserved.
What is important, is that the devm_iio_kfifo_buffer_setup() be called
after the indio_dev->modes is assigned, to make sure that
INDIO_BUFFER_SOFTWARE flag is set and not overridden by the assignment to
indio_dev->modes.
Also, the INDIO_BUFFER_SOFTWARE has been removed from the assignments of
'indio_dev->modes' because it is set by devm_iio_kfifo_buffer_setup().

If we are using edge IRQs, new samples can arrive while processing
current interrupt since there are no hw guarantees the irq line
stays "low" long enough to properly detect the new interrupt.
In this case the new sample will be missed.
Polling FIFO status register in st_lsm6dsx_handler_thread routine
allow us to read new samples even if the interrupt arrives while
processing previous data and the timeslot where the line is "low"
is too short to be properly detected.

Set 10ms as minimum i2c slave configuration timeout since st_lsm6dsx
relies on accel ODR for i2c master clock and at high sample rates
(e.g. 833Hz or 416Hz) the slave sensor occasionally may need more cycles
than i2c master timeout (2s/833Hz + 1 ~ 3ms) to apply the configuration
resulting in an uncomplete slave configuration and a constant reading
from the i2c slave connected to st_lsm6dsx i2c master.

One of a class of bugs pointed out by Lars in a recent review.
iio_push_to_buffers_with_timestamp assumes the buffer used is aligned
to the size of the timestamp (8 bytes). This is not guaranteed in
this driver which uses an array of smaller elements on the stack.
As Lars also noted this anti pattern can involve a leak of data to
userspace and that indeed can happen here. We close both issues by
moving to an array of suitable structures in the iio_priv() data.
This data is allocated with kzalloc so no data can leak apart from
previous readings.
For the tagged path the data is aligned by using __aligned(8) for
the buffer on the stack.
There has been a lot of churn in this driver, so likely backports
may be needed for stable.

Scaling factor values for Acc lead to an unacceptable rounding of the
full scale (FS) calculated by some SensorHAL on Android devices. For examples
setting FS to 4g the in_accel_x_scale, in_accel_y_scale and in_accel_z_scale
are 0.001196 on 6 decimal digits and the FS is
0.001196 × ((2^15) − 1) ~= 39.1893 m/s^2.
Android CTS R10 SensorParameterRangeTest test expects a value greater than
39.20 m/s^2 so this test fails (ACCELEROMETER_MAX_RANGE = 4 * 9.80).
Using 9 decimal digits the new scale factor is 0.001196411 and the FS now
is 0.001196411 × ((2^15)−1) ~= 39.2028 m/s^2.
This patch extends to IIO_VAL_INT_PLUS_NANO type the scaling factor to all
IMU devices where SensorParameterRangeTest CTS test fails.

This patch applies the semantic patch:
@@
expression I, P, SP;
@@
I = devm_iio_device_alloc(P, SP);
...
- I->dev.parent = P;
It updates 302 files and does 307 deletions.
This semantic patch also removes some comments like
'/* Establish that the iio_dev is a child of the i2c device */'
But this is is only done in case where the block is left empty.
The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.
In other cases, the block covered by ... may be just too big to be covered
by the semantic patch.
However, this looks pretty good as well, as it does cover a big bulk of the
drivers that should remove the parent assignment.

At the moment, attempting to probe a device with ST_LSM6DS3_ID
(e.g. using the st,lsm6ds3 compatible) fails with:
st_lsm6dsx_i2c 1-006b: unsupported whoami [69]
... even though 0x69 is the whoami listed for ST_LSM6DS3_ID.
This happens because st_lsm6dsx_check_whoami() also attempts
to match unspecified (zero-initialized) entries in the "id" array.
ST_LSM6DS3_ID = 0 will therefore match any entry in
st_lsm6dsx_sensor_settings (here: the first), because none of them
actually have all 12 entries listed in the "id" array.
Avoid this by additionally checking if "name" is set,
which is only set for valid entries in the "id" array.
Note: Although the problem was introduced earlier it did not surface until
commit 52f4b1f196 ("iio: imu: st_lsm6dsx: add support for accel/gyro unit of lsm9ds1")
because ST_LSM6DS3_ID was the first entry in st_lsm6dsx_sensor_settings.

- Split the existing LTC2497 driver generic component out and reuse.
- DT bindings.
* parallax ping
- New driver supporting ultrasonic and laser tof distance sensors.
- Bindings for these sensors.
New features
* core
- New char type for read_raw returns, used for thermocouple types.
- Rename read_first_n callback to read. The reasons behind the original
naming are lost to the mists of time.
* ad799x
- Allow pm_ops to disable device completely allowing regulator power down.
* bma180
- Enable basic regulator support.
* dmaengine buffer
- Report platform data alignment requirements via new ABI.
* max31856
- Add option to set mains filter rejection frequency and document
new in_temp_filter_notch_center_frequency ABI.
- Add support for configuring HW averaging (oversampling ratio)
- Add runtime configuration of thermocouple type and document new ABI.
* maxim-thermocouple
- Add read only access to thermocouple type using new ABI, includes
adding more specific compatibles to reflect which variant of the
chip is being used.
* mpu6050
- Provide option to support the PMU9150 in package magnetometer directly
rather than via auxiliary bus.
* stm32_adc
- Add overrun interrupt checks to detect if this happens.
* st_lsm6dsx
- Enable the sensor-hub support for lsm6dsm. Includes various reworks to
allow this.
Cleanups and minor fixes
* Subsystem wide
- Tidy up indentation in Kconfig and fix alphabetical order of AD7091R5.
- Drop linux/gpio.h and linux/of_gpio.h from drivers that don't use them.
* ad7266
- Convert to GPIO descriptors.
* ad7303
- Avoid a dance with checking if the regulator is supplied by just
using the optional request interface.
* ad7887
- Simplify channel specification assignment to enable adding more devices.
* ad7923
- Drop some unused and largely pointless defines of BOB_N==N variety.
- Tidy up checkpatch warnings.

* ak8975
- Convert to GPIO descriptors.
* ADIS library and drivers
- Expand scope of txrx_lock to cover all state and rename as state_lock
- Add unlocked read / write to allow grouping of consecutive calls under
single lock / unlock.
- Add unlocked check_status, reset to allow grouping under single
lock / unlock.
- Remove remaining uses of core mlock for local state protection.
mlock should never be used directly as it protects tightly defined
core IIO device management state.
* adis16240
- Enforce only supported SPI mode on driver load + add DT binding doc.
* atlas-ph-sensor
- Rename to atlas-sensor given it now covers things beyond ph sensors.
* bma180
- Use local dev variable to tidy up code.
- Use c99 style explicity .member assignment to make driver more readable.
* bmp280
- Drop ACPI support. No evidence this was used and appropriate ID is not
registered.
- Allow ACPI to bind device via PRP0001
* dmaengine buffer
- Use dma_request_chan instead of dma_request_slave_channel_reason as that
ABI is going away.
- Add module info to avoid tainting the kernel.
* hts221
- Avoid magic number defines when only used to fill structure elements
that are self describing.
* lm3533
- Drop a stray semicolon.
* max9611
- Cleanup enum handling to be more resilient to future changes.
* mpu6050
- Delete MPU9150 from supported SPI devices as doesn't provide SPI.
- Select I2C_MUX again after kbuild issue fixed elsewhere.
* stm32-timer
- Drop an unnecessary register update.
* ssp_sensors
- Convert to GPIO descriptors.
* st_sensors
- drop !CONFIG_ACPI defines as ACPI_PTR() will stop them being used
anyway.
- Make default platform data structures __maybe_unsued.
- Fill in some missing kernel-doc function parameters.

First set of new device support, features and cleanups for IIO in the 5.6 cycle
New device support
* ad7091r5 ADC
- New driver with follow up patch adding scale and vref support.
- DT bindings
* ad7923
- Support for ad7908, ad7918 and ad7928 added to driver.
* bma180
- Support the BMA254 accelerometer. Required fairly substantial rework
to allow for small differences between this an existing parts.
* bma400 accelerometer
- New driver with follow up patch for regulator support.
- DT bindings.
* asc dlhl60d
- New driver support this range of pressure and temperature sensors.
- DT bindings.
* ltc2496 ADC
- New driver to support this ADC.
- Split the existing LTC2497 driver generic component out and reuse.
- DT bindings.
* parallax ping
- New driver supporting ultrasonic and laser tof distance sensors.
- Bindings for these sensors.
New features
* core
- New char type for read_raw returns, used for thermocouple types.
- Rename read_first_n callback to read. The reasons behind the original
naming are lost to the mists of time.
* ad799x
- Allow pm_ops to disable device completely allowing regulator power down.
* bma180
- Enable basic regulator support.
* dmaengine buffer
- Report platform data alignment requirements via new ABI.
* max31856
- Add option to set mains filter rejection frequency and document
new in_temp_filter_notch_center_frequency ABI.
- Add support for configuring HW averaging (oversampling ratio)
- Add runtime configuration of thermocouple type and document new ABI.
* maxim-thermocouple
- Add read only access to thermocouple type using new ABI, includes
adding more specific compatibles to reflect which variant of the
chip is being used.
* mpu6050
- Provide option to support the PMU9150 in package magnetometer directly
rather than via auxiliary bus.
* stm32_adc
- Add overrun interrupt checks to detect if this happens.
* st_lsm6dsx
- Enable the sensor-hub support for lsm6dsm. Includes various reworks to
allow this.
Cleanups and minor fixes
* Subsystem wide
- Tidy up indentation in Kconfig and fix alphabetical order of AD7091R5.
- Drop linux/gpio.h and linux/of_gpio.h from drivers that don't use them.
* ad7266
- Convert to GPIO descriptors.
* ad7303
- Avoid a dance with checking if the regulator is supplied by just
using the optional request interface.
* ad7887
- Simplify channel specification assignment to enable adding more devices.
* ad7923
- Drop some unused and largely pointless defines of BOB_N==N variety.
- Tidy up checkpatch warnings.
- Add missing of_device_id table.
* adf4350
- Convert to GPIO descriptors.
* ak8975
- Convert to GPIO descriptors.
* ADIS library and drivers
- Expand scope of txrx_lock to cover all state and rename as state_lock
- Add unlocked read / write to allow grouping of consecutive calls under
single lock / unlock.
- Add unlocked check_status, reset to allow grouping under single
lock / unlock.
- Remove remaining uses of core mlock for local state protection.
mlock should never be used directly as it protects tightly defined
core IIO device management state.
* adis16240
- Enforce only supported SPI mode on driver load + add DT binding doc.
* atlas-ph-sensor
- Rename to atlas-sensor given it now covers things beyond ph sensors.
* bma180
- Use local dev variable to tidy up code.
- Use c99 style explicity .member assignment to make driver more readable.
* bmp280
- Drop ACPI support. No evidence this was used and appropriate ID is not
registered.
- Allow ACPI to bind device via PRP0001
* dmaengine buffer
- Use dma_request_chan instead of dma_request_slave_channel_reason as that
ABI is going away.
- Add module info to avoid tainting the kernel.
* hts221
- Avoid magic number defines when only used to fill structure elements
that are self describing.
* lm3533
- Drop a stray semicolon.
* max9611
- Cleanup enum handling to be more resilient to future changes.
* mpu6050
- Delete MPU9150 from supported SPI devices as doesn't provide SPI.
- Select I2C_MUX again after kbuild issue fixed elsewhere.
* stm32-timer
- Drop an unnecessary register update.
* ssp_sensors
- Convert to GPIO descriptors.
* st_sensors
- drop !CONFIG_ACPI defines as ACPI_PTR() will stop them being used
anyway.
- Make default platform data structures __maybe_unsued.
- Fill in some missing kernel-doc function parameters.
* st_lsm6dsx
- white space fixes.
- Mark some constants that aren't always used as __maybe_unused.
- Drop of ID table guards as they just pervent use under ACPI.
- Switch to device properties to allow ACPI usage.
* st_uvis25
- Drop acpi.h include as no ACPI APIs used.
* ti-ads1015

On LSM6DSO/LSM6DSR/LSM6DSOX/ASM330LHH and ISH330DHCX
devices it is possible to trim the hardware timestamp
resolution through the FREQ_FINE[7:0] bits of the
INTERNAL_FREQ_FINE register, which contains the difference
in percentage of the effective ODR (and timestamp rate)
with respect to the typical value.
The formula for calculating the effective ODR reported
in the application notes has been linearized to the first
order to simplify the calculation (pls. see note on source
code).
This change may be useful in the outcome of CTS
tests regarding the SingleSensorTests and the
SensorTest#testSensorTimeStamps for high ODRs

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.

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.
