IIO new device support, features, cleanup for 7.3

Includes a merge of 7.2-rc2 to pick up the changes around
mod_devicetable.h and reduce resulting conflicts around includes.

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

adi,ad3530R
- Add support for the AD3532R and AD3532 16 channel DACs.
adi,ad4080
- Add support for the AD4883 ADC.
adi,ad5686
- Add support for AD5313R, AD5317R, AD5674, AD5687R, AD5689, AD5689R DACs
over SPI
- Add support for AD5316R, AD5674, AD5697R and AD5696 DACs over I2C
- Significant driver refactoring prior to these additions, partly to reduce
bus traffic and to add triggered buffer and gain control support. An
earlier set added support for missing supplies, reset and LDAC GPIO.
adi,adf41513
- New driver to support this PLL frequency synthesizer that runs up to
26.5 GHz.
- Included infrastructure to handle higher precision attributes with
extensive tests
adi,ltc2378-20
- New driver supporting LTC2338, LTC2364, LTC2367, LTC2368, LT2369, LTC2370
LTC2376, LTC2377, LTC2378, LTC2379 and LTC23980 ADCs with both high speed
capture via appropriate backend and conventional triggered buffer SPI
capture.
invensense,icm42607
- New driver for this IMU.
mediateck,mt6323
- New driver for this PMIC ADC.
microchip,mcp47a1
- New driver for this I2C 6 bit DAC.
nxp,mcf54415-dac
- New driver for this DAC found in NXP SoCs.
qst,qmc5884l
- New driver for this 3 axis magnetometer. Included dt vendor entry for qst.
qst,qmc6308
- New driver for this 3 axis magnetometer.
sensiron,slf3s
- New driver for this liquid flow sensor. Includes adding IIO_VOLUMEFLOW
channel type.
st,vl53l1x
- Refactors to improve readability.
ti,ads112c14
- New driver supporting the ADS112C14 and ADS122C14 ADCs. These bring
some new ABI for input chopping, particular useful for resistive sensors
like thermocouples or Wheatstone bridges.
- Support CRC8 detection of corruption on the bus.
- Support buffered reads.
ti,tmp117
- (trivial) Add support for the tmp119 temperature sensor.
xilinx,versal-sysmon
- New ADC driver for this block found on various FPGAs including various
bus interfaces, threshold and oversampling support.

dt binding updates
------------------
new shared bindings
- excitation-channels and excitation-current-nanoamp allow per channel
specification of currents used for resistive sensor measurement.
- reference-sources property to allow selection of a per channel reference.
rockchip,saradc
- Add RV1106 which is compatible with the RV3588.

Features
--------

buffer-dmaengine
- Allow cyclic buffers, useful for repeating sequence generation with DACs.
devantech,dmard09
- Implement read back of channel scale - previously interface always
returned an error.
hid,sensors-als
- Enable separate channel scaling for hardware that supports it.
invensense,timestamp library
- Various precision improvements.
invensense,icm42600
- Add support for hwfifo watermark interfaces.
taos,tcs3472
- Support wait time and sampling frequency control.

Cleanups, minor fixes
---------------------

Minor cleanups not mentioned at all in this summary such
as white space fixes or typos.

Affecting various drivers
- Cleanup of conditionals that had no affect.
- Drop some runtime pm local wrappers as now runtime_pm does the
mark_last_busy part inside the put, these provide no useful code
deduplication or readability advantages over directly calling the
runtime_pm functions.
- Return 0 from write_raw() on success.
- Use of dev_err_probe() to simplify code and sometimes provide useful
info for deferred probe debugging.
- Drop some redundant error prints where the called function already
provides information on errors.
- Make some read only arrays in functions static.
- Fix up missing handling of regcache_sync() errors.
- Drop some false kernel-doc markings.
- Add missing MODULE_DEVICE_TABLE for some of_match_id tables.
- Use local variables for things like the struct device to shorten and
improve readability of code.
- Drop some unused structure elements.
- Reorder dds.h macro parameters to be inline with others.
- Header reorders and IWYU. Often part of a more significant series.
- Remove abstractions designed to allow a driver to support multiple device
types, when they have been around a long time and only the original part
showed up.
- Initialize spi_device_id arrays using member names following dropping of
driver data from drivers that didn't actually use it.
- Catch up with i2c_device_id tables added since previous effort to use
named initializers for all those.
- Use kernel types in a few places instead of standard C ones or bare
unsigned.

Misc
- Update Xilinx AMS maintainer.
- Update email address for Maxwell Doose.
- Update email address for Siratul Islam.
- Update email address for Tomasz Duszynski and re-add Tomasz to
various maintainer entries.
Docs
- Encourage use of differential channel naming even when there is no
flexibility in input to differential pair mapping. Intended to
provide a strong signal to userspace that a channel is differential.
adi,ad_sigma_delta
- Allow COMPILE_TEST without any users.
adi,ad2s1201
- Refactor trigger handler to avoid mix of guard() and goto.
adi,ad5686
- Avoid potential NULL dereference is user forces a driver bind.
adi,ad5696
- Add a couple of missing entries to the of_match_id table and update
binding to match.
atmel,ad91_adc
- Use const char * for DT string property allowing a cast to be dropped.
avia,hx711
- Various refactors and cleanup to enable support of additional parts
(to come)
- Add missing supply and gpio dt-bindings.
bosch,bmc150
- Harden against device reporting too large a FIFO sample count.
- Use FIELD_PREP() / FIELD_GET() to improve readability.
freescale,fxls8962af
- Harden against device reporting too large a FIFO sample count.
hid-sensors-*
- Reorder probe to not expose userspace interfaces until the rest of
the setup is done to avoid potentially dropping data.
honeywell,abp2030pa
- Drop an unreachable return.
invensens,icm45600
- Harden against bad value of FIFO sample count from device.
- Use i2c_match_data if firmware table sourced match data isn't available.
nxp,mpl1115
- Ensure runtime_pm is balanced on error in probe.
rohm,bm1390
- Make the driver slightly more likely to recover from transient errors.
sensiron,sgp30
- Handle thread creation errors.
st,lsm6dsx
- Update the enable mask when doing sensor fusion to avoid incorrect fifo
data handling.
st,stm32-dfsdm
- Treat dt flags as booleans.
ti,ads1015
- Switch to devm helpers which simplified code and closed a resource leak.
ti,opt3001
- Split complicated opt3001_get_processed() logic into irq an no irq
helper functions.
- Use devm to simplify code.
- Use guard() to simplify code.
- Reorder probe so final call exposes userspace interfaces.
- Various other more minor cleanup
taos,tsl2772
- Fix calibscale readback to check right channel type.
taos,tsl2583
- Use sysfs_emit() and sysfs_emit_at() to replace open coded equivalents.
