1st set of IIO new device support, feature and cleanup for 6.2 (take2)
We have finally managed to take the mlock mutex entirely private so as
to avoid it being used for multiple purposes. Now it is just used to
protect device mode transitions (typically to and from buffered capture).
Includes merge of an immutable i2c branch to get the new
i2c_client_get_device_id() (thanks to Wolfram for providing the branch).
Based on rc3 to pick up some precursor fixes from early in the cycle and
avoid an unnecessarily messy history.
New device support
* adi,ad4310
- New driver to support this very flexible measurement device including
a 24 bit ADC. Later fix for documentation build issue.
* adi,adxl355
- Add support of the ADXL359 accelerometer.
* adi,ltc2983
- Support additional variants of the temperatures sensor:
LTC2984 with an EEPROM
LTC2985, LTC2986 with only 10 channels.
* invensense,icm42600
- Add support for icm42631 (needed only ID and WHOAMI)
* kionix,kx022a
- New driver for this 3 axis accelerometer.
* maxim,max11401
- New driver to support this 24-bit 10 channel ADC.
Includes some new ABI to support configuration of notch filters.
* mediatek,mt6370
- Add new driver to support the ADC part of the mt6370.
* st,lsm6dsx
- Add support for LSM6DSV accelerometer and gyroscope. Simple additional
of chip specific data and IDs.
- Add support for LSM6DSV16X accelerometer and gyroscope. Compatible with
features currently implemented for the LSM6DSV.
* st,stm32-adc
- Add support for stm32pm13x SoCs.
core / subsystem wide:
- Add new IIO_STATIC_CONST_DEVICE_ATTR() which is a dance necessary to
allow for the wrapping of attributes in the code that duplicates them
for multiple buffers.
- Harden against future issues with expectation that all buffer attributes
are iio_dev_attrs by changing the code to take an array of pointers
of the correct type.
- Last transitions of drivers to local locks rather than missuses of mlock.
- Add an iio_device_claim_buffer_mode() callback to avoid a race in the
max30100 driver without directly using mlock.
- Move mlock to the opaque IIO device structure to prevent misuse.
- Add missing spi_device_id tables to support auto loading of modules.
- Update some ADI maintainers in DT bindings.
- A few more moves of bus drivers and core module sets to export
name spaces.
- Extensive use of new devm_regulator_get_enable() and friends.
- Switch a bunch of i2c drivers to probe_new() including the bmp280
which makes use of the new i2c_client_get_device_id() helper to
simplify this change.
dt-bindings:
- More use of spi-peripheral-props.yaml.
Features
* freescale,mpl115
- Use runtime PM to implement shutdown GPIO support.
* melexis,mlx90632
- More sophisticated runtime power management
- Provide access to sampling frequency.
- Trivial follow up fixes.
* microchip,mcp3911
- Support control of PGA.
* st,lsm6dsx
- Add support for software triggers for cases where the IRQ lines
are not wired up.
* vishay,vcnl4000
- Add control of integration time.
Minor cleanups and fixes
* adi,ad4130
- Improve ABI documentation formatting.
- Kconfig dependency fixup.
* adi,ad5758
- Minor dt binding fix.
* adi,ad9834
- Tidy up line breaks.
* adi,ade7854
- Minor improvement in code clarity by replacing a ternary.
* adi,admv8818
- Harden code against hardware returning wrong values.
* adi,adxl355
- Warn only if unknown device ID detected to allow for fall back
device tree compatibles on future devices.
* adi,ltc2983
- dt-bindings clarifications and general improvements.
- Ensure DMA safe buffer for bulk writes without relying on current
regmap implementation choices.
* avago,adps9960
- Fix up a disconnect between event enable attributes and what was
enabled.
* bosch,bma400
- Switch to dev_err_probe() from open coded EPROBE_DEFER handling.
* cosmic,cc10001
- Fully devm managed probe() and related tidying up.
* meas,ms5611
- Add an example of spi-max-frequency.

MPL115 supports shutdown gpio which can be used to set the state
to low power mode. Power from all internal circuits and
registers is removed. This is done by pulling the SHDN pin to low.
This patch enables runtime PM on MPL115 to increase power savings.
According to spec., a wakeup time period of ~5 ms exists between
waking up and actually communicating with the device. This is
implemented using sleep delay.

The DPS310 chip has been observed to get "stuck" such that pressure
and temperature measurements are never indicated as "ready" in the
MEAS_CFG register. The only solution is to reset the device and try
again. In order to avoid continual failures, use a boolean flag to
only try the reset after timeout once if errors persist.

Adds DMA-safe buffers to driver data struct to store raw data from sensors
The multiple buffers used thorough the driver share the same memory

Simplified common initialization logic of different sensor types
unifying calibration and initial configuration recovery.
Default config param values of each sensor type are stored inside
chip_info structure and used to initialize sensor data struct instance.
The helper functions for read each sensor type calibration are converted
to a callback available on the chip_info struct.
Separated bme280 specific calibration code from bmp280 function. Dropped
the additional chip_id argument in bmp280 code as is not longer required.
Now both bmp280/bme280 calibration function use same signature as bmp180.

The suspend and resume callbacks in this driver appear to be safe
to call repeatedly, but why do so when we can use the
DEFINE_RUNTIME_DEV_PM_OPS() macro to supply callbacks that check if
we are already runtime suspended before doing unnecessary work.

The value returned by an i2c driver's remove function is mostly ignored.
(Only an error message is printed if the value is non-zero that the
error is ignored.)
So change the prototype of the remove function to return no value. This
way driver authors are not tempted to assume that passing an error to
the upper layer is a good idea. All drivers are adapted accordingly.
There is no intended change of behaviour, all callbacks were prepared to
return 0 before.

Instead of registering callback to process sensor events right at
initialization time, wait for the sensor to be register in the iio
subsystem.
Events can come at probe time (in case the kernel rebooted abruptly
without switching the sensor off for instance), and be sent to IIO core
before the sensor is fully registered.

device.
* "accel-display" : the sensor is in the lid/display plane of the
device.
* "accel-camera" : the sensor is in the swivel camera subassembly.
The non-standard |location| attribute is removed, the field |loc| in

Letting the compiler remove these functions when the kernel is built
without CONFIG_PM_SLEEP support is simpler and less error prone than the
use of #ifdef based config guards.
Removing instances of this approach from IIO also stops them being
copied into new drivers.

The core module and type specific core modules are made up of
several files. There is no benefit in duplicating the MODULE_* macros
in each file so remove them.
Noticed whilst adding MODULE_IMPORT_NS() as I missed some files and
it still worked, making it clear not all of these blocks were needed.
