IIO: 1st set of new device support, features and cleanup for 6.12

Includes a merge of spi-mos-config branch from spi.git that brings
support needed for the AD4000 driver.

Lots of new device support this time including 9 new drivers and substantial
changes to add new support to several more.

New device support
------------------

Given we have a lot of new support, I've subcategorized them:

Substantial changes, or new driver
**********************************

adi,ad4000
- New driver for this high speed ADC.
adi,ad4695
- New driver supporting AD4690, AD4696, AD4697 and AD4698 ADCs.
- Follow up series added triggered buffer support.
adi,ad7380
- Add support for single ended parts, AD7386, ADC7387, AD7388 and -4 variants.
(driver previously only support differential parts).
These variants have an additional front end MUX so only half the channels
can be sampled efficiently.
adi,ad9467
- Refactor and extend driver to support ad9643, ad9449 and ad9652 high speed
ADCs.
adi,adxl380
- New driver for this low power accelerometer.
adi,ltc2664
- New driver supporting LTC2664 and LTC2672 DACs.
microchip,pac1921
- New driver for this power/current monitor chip.
rohm,bh1745
- New driver for this RGBC colour sensor.
rohm,bu27034anuc
- The original bu27034 was canceled before mass production, so the
driver is modified to support the BU27034ANUC which had some significant
differences. DT compatible changed to avoid chance of old driver ever
binding to real hardware.
sciosense,ens210
- New driver for ens210, ens210a, ens211, ens212, ens213a, and ens215
temperature and humidity sensors (all register compatible up to some
conversion time differences)
sensiron,sdp500
- New driver for this differential pressure sensor.
tyhx,hx9023s
- New driver to support this capacitive proximity sensor.

Minor changes to support new devices
************************************

adi,adf4377
- Add support for the single output adf4378.
kionix,kxcjk-1013
- Add support for KX022-1020 accelerometer (binding and ID table only)
liteon,ltrf216a
- Add support for ltr-308. A few minor differences in features set
rockchip,saradc
- Add ID for rk3576-saradc
sensortek,stk3310
- Add ID for stk3013 proximity sensor which (despite documentation) has
an ambient light sensor and is compatible with existing parts.

Documentation updates
---------------------

Generalize ABI docs for shunt resistor attribute
Improve calibscale and calibbias related documentation. A couple of follow
up patches to resolve duplicate documentation that resulted.

New core features
-----------------

backend
- Add option for debugfs - useful for test pattern control
- Use this for both adi-axi-adc and adi-axi-dac
trigger suspend
- Add functions to allow triggers to be suspended. This avoids problems
when a device enters suspend to idle with a sysfs trigger. Use it for now
in the bmi323 only.

New driver features
-------------------

adi,ad7192
- Add option to be a clock provider (+ additional clock config options)
adi,ad7380
- Add documentation for this fairly new driver.
adi,ad9461
- Provide control of test modes and backend validation blocks used
to identify problems (via debugfs)
adi,ad9739
- Add backend debugfs and docs for what is provided via adi-axi-dac
avago,apds9960
- Add proximity and gesture calibration offset control
bosch,bmp280
- Triggered buffer support including adding raw+scale output for sysfs.
liteon,ltr390
- Add configuration of integration time and scale.
stm,dfsdm
- Convert this SD modulator driver to backend framework and add support
for channel scaling + modern channel bindings.

Treewide cleanup
----------------

iio_dev->masklength: Making it private.
- Provide access function to read the core compute channel mask length
and a macro to iterate over elements in the active_scan_mask.
- Enables marking masklength __private preventing drivers from
writing it without triggering a build warning whilst minimizing overhead
in what are typically hot paths.
- Convert all drivers and finally mark it private.
Merge conflicts resolved in drivers applied after this point.
Constify regmap_bus
- These are never modified, so mark them const.

Core cleanup
------------

backend
- A few late breaking bits of feedback (unused variable, error messages)
dma-buffer
- Namespace exports.
core
- Drop unused assignment.

Driver cleanup
--------------

adi,ad4695
- Fixing binding to reflect that common-mode-channel is a scalar.
adi,ad7280a
- Use __free(kfree) to simplify freeing of receive buffer.
adi,ad7606
- Various dt-binding cleanup and improvements.
- Fix oversampling related gpio handling.
- Make polarity of standby gpio match documentation.
- use guard() to simplify lock handling.
adi,ad7768
- Use device_for_each_child_node_scoped() instead of fwnode equivalent.
adi,ad7124
- Reduce SPI transfers by avoiding separate writes to different fields
in the same register.
- Start the ADC in idle mode.
adi,adis
- Drop ifdefs in favor of IS_ENABLED.
adi,admv8818
- Fix wrong ABI docs.

property is there or not.
atmel,at91,
- Use __free(kfree) to simplify freeing of channel related array.
bosch,bma400
- Use __free(kfree) to simplify freeing a locally allocated string.
bosch,bmc150
- Add missing mount-matrix binding docs.
bosch,bme680
- Fix read/write to ensure multiple necessary sequential reads without
device configuration change.
- Drop unnecessary type casts and use more appropriate data types.
- Drop some left over ACPI code as ACPI support was removed due to invalid
IDs (and no known users).
- Sort headers consistently.
- Avoid unnecessary duplicate read and redundant read of gas config.
- Use bulk reads to get calibration data.
- Reorder allocation of IIO device to be prior to device init.
- Add remaining read/write buffers to the union used already for all others.
- Tidy up error checks for consistency of style, including dev_err_probe()
- Bring the device startup procedure inline with the vendor code.
- Reorder code so mode forcing is more obvious occurring where needed.
- Tidy up data locality in reading functions so no magic data is stored
in state structures just to get it across function calls.
- Make a local lookup table static to avoid placing it on the stack.
bosch,bmp280
- Fix BME280 regmap to not include registers it doesn't have.
- Wait a little longer after config to allow for maximum possible necessary
wait.
- Reorganize headers.
- Make conversion_time_max array static to avoid placing it on the stack.
maxim,max1363
- Use __free(kfree) to simplify freeing transmission buffer.
microchip,mcp3964
- Use devm_regulator_get_enable_read_voltage()
microchip,mcp3911
- Use devm_regulator_get_enable_read_voltage()
microchip,mcp4728
- Use devm_regulator_get_enable_read_voltage()
microchip,mcp4922
- Use devm_regulator_get_enable_read_voltage() and devm_* to allow
dropping of explicit remove() callback.
onnn,noa1305
- Various tidy up.
- Provide available scale values.
- Make integration time configurable.
- Fix up integration time look up (/2 error)
ti,dac7311
- Check if spi_setup() succeeded.
ti,tsc2046
- Use __free(kfree) to simplify freeing rx and tx buffers.
- Use devm_regulator_get_enable_read_voltage()

Various minor fixes not called out explicitly.

iio: chemical: bme680: Refactorize reading functions

The reading of the pressure and humidity value, requires an update of the
t_fine variable which happens by reading the temperature value.

So the bme680_read_{press/humid}() functions of the above sensors are
internally calling the equivalent bme680_read_temp() function in order to
update the t_fine value. By just looking at the code this relation is a
bit hidden and is not easy to understand why those channels are not
independent.

This commit tries to clear these thing a bit by splitting the
bme680_{read/compensate}_{temp/press/humid}() to the following:

i. bme680_read_{temp/press/humid}_adc(): read the raw value from the
sensor.

ii. bme680_calc_t_fine(): calculate the t_fine variable.

iii. bme680_get_t_fine(): get the t_fine variable.

iv. bme680_compensate_{temp/press/humid}(): compensate the adc values and
return the calculated value.

v. bme680_read_{temp/press/humid}(): combine calls of the aforementioned
functions to return the requested value.

iio: chemical: bme680: Move forced mode setup in ->read_raw()

Whenever the sensor is set to forced mode, a TPHG cycle is triggered and
the values of temperature, pressure, humidity and gas become ready to be
read.

The setup of the forced mode to trigger measurements was located inside
the read_{temp/gas}() functions. This was not posing a functional problem
since read_{humid/press}() are internally calling read_temp() so the
forced mode is set through this call.

This is not very clear and it is kind of hidden that regardless of the
measurement, the setup of the forced mode needs to happen before any
measurement.

There is no need to explicitly configure the gas measurement registers
every time a gas measurement takes place. These are initial configurations
which are written in the beginning and they are not changed throughout
the lifetime of the driver.

If in the future, the device starts to support multiple configuration
profiles with variable heater duration and heater temperature, then they
could become members of the ->read_avail().

Modify the startup procedure to reflect the procedure of the Bosch BME68x
Sensor API. The initial readings and configuration of the sensor need to
happen in the following order:

1) Read calibration data [1,2]
2) Chip general configuration [3]
3) Gas configuration [4]

After the chip configuration it is necessary to ensure that the sensor is
in sleeping mode, in order to apply the gas configuration settings [5].

Also, after the soft reset, it is advised to wait for 5ms [6].
