IIO: New devices support, features and cleanup for 7.1

Includes merge of v7.0-rc4 to pull in a fix and a merge of
ib-iio-thermal-qcom-pmic5 immutable branch (provided from the IIO tree so
thermal could also pick this up and add thermal specific remainder
of the series on top.

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

adi,ad4030
- Add support for ADA4316 and ADAQ4224 ADCs with PGAs.
adi,ad4080
- Add support for AD4082, AD4085 and AD4088 ADCs.
adi,ad8366
- Add ADRF5702 and ADRF5703 digital step attenuators.
adi,adxl372
- Add support for the ADXL371 accelerometer after refactors to allow multiple
  device variants to be supported by the driver. In particular a silicon
  issue means the hardware FIFO doesn't work on the ADXL371
bosch,bma255/bmg160
- Add support for BMX055 gyroscope and magnetometer (effectively separate
  devices from point of view of interface).
lltc,ltc2309
- Add support for LTC2305 2 channel 12-bit ADC.
lltc,ltc2532
- Add support for 4 variants of the LTC2654 quad DAC.
maxim,ds4424
- Add IDs for DS4402 and DS4404 parts. Initially patch is ID only but additional
  features also added that are device dependent.
qcom,spmi-adc-gen3
- New driver supporting this generation of Qualcomm's SoC ADC.
st,vl53l1
- New driver for this Time Of Flight (TOF) sensor.
ti,ina2xx
- Support the INA236 digital power monitor.
vishay,vcnl4000
- Add support for CM36686 ambient light and proximity sensor.
- Add support for CM36672P proximity sensors.

ID only additions.
amlogic,meson-adc
- Support the Meson S4.

Features
--------

iio-backend framework
- Add capability discovery so front end drivers can know what features are
  available from the backend and adjust how they operate.
adi,ad4030
- Add SPI offload support requiring a non trivial PWM setup.
adi,ad7380
- Add support for multiple SPI lanes to improve throughput.
adi,ad7768-1
- Support SPI offload and always use continuous mode, enabling more
  filter options.
adi,ad8366
- Device tree bindings and support.
aspeed,adc
- Handle battery channel.
maxim,ds4424
- Add external resistor controlled scale and per-variant limits.
- Handle per variant range limits.
- Move it to regmap.
motorola,cpcap-adc
- Support for the ADC found on the Motorola Mot board. Effectively some board
  specific configuration handled in the driver.
vishay,vcnl4000
- Support explicit power supply regulators.
tyhx,hx9023s
- Allow device tree specification of firmware file name.

Cleanup and minor fixes
-----------------------

treewide
- Remove a bunch of unused structure elements.
- Replaces standard fixed width integers with kernel types.
- Replace some other error values that were returned on allocation failure
  with -ENOMEM
iio-core
- Replace a few custom devm implementations for devm_add_action_or_reset()
iio-trigger
- Use put_device() to cleanup on error.
iio-backend
- Use __free(fwmode_handle) to simplify some code.
hw-consumer
- Use separate allocation for scan mask bitmap to simplify code.
acpi-als
- Switch from ACPI driver to platform driver.
adi,ad4030
- Use BIT() to replace values that are always a power of 2 to slightly
  improve readability.
adi,ad4062
- Add a missing check for error form iio_get_current_scan_type()
adi,ad5933
- Use div64_ul() rather than do_div() as remainder was not used.
adi,ad7191
- Documentation fixes related to clocks
adi,ad7816
- Use sysfs_emit()
adi,ad8366
- General driver modernization
adi,adf4350
- Change a TOOD to NOTE in a comment to avoid anyone from walking into
  a tricky to improve corner case.
adi,admv1013
- Avoid a null pointer dereference if device_property_read_string() fails.
adi,admv4420
- Return error code rather than -1..
adi,adxl345
- Add separate scaling for events from that of raw channels.
amlogic,meson-adc
- Don't bother keeping nvmem cell access around when only used in probe.
atmel,at91-sama5d
- Don't bother keeping nvmem cell access around when only used in probe.
bosch,bmc150
- Use sysfs_emit() in a few places.
honeywell,hsc030pa
- Improve handling of return values from i2c_transfer.
liteon,ltr501
- Return error values rather than -1 replaced by -EINVAL at higher
  levels of the callstack.
maxim,ds4424
- A bunch of general minor improvements prior to adding new features.
maxim,max11410
- Make some const string arrays static.
maxim,max5522
- Use devm_regulator_get_enable_read_voltage() at probe to cache the
  voltage rather than keeping the regulator around to access and query
  later.
vishay,vcnl4000
- Various code improvements.
sharp,gp2ap020a00f
- General driver modernization.
silabs,si7210
- Use devm_regulator_get_enable_read_voltage() at probe to cache the
  voltage rather than keeping the regulator around to access and query
  later.
st,lsm6dsx
- Add SMOCF00 ACPI ID seen on products by SHIFT.
st,st_sensors
- Fix up various kernel-doc issues.
- Avoid kmalloc of a single use buffer and instead reused existing
  buffer_data.
taos,tsl2772
- Fix some kernel-doc warnings due to missing :
ti,ads7950
- Use iio_push_to_buffers_with_ts_unaligned() as first few elements of
  array are not the data that is pushed.
- Move from array of chip_info structures to individual named ones. This
  is part of slowly replacing use of a code pattern that we don't want
  replicated in new drivers.
vti,sca3000
- General driver modernization included use of devm and guard().

Various other more minor stuff not called out explicitly.
Includes things like typo fixes, use of dev_err_probe() and local
variables to avoid repeated dereferencing of the same member as well as
increasing use of guard() to simplify release of locks.

Another slow improvement to code quality is both standardizing on
header order and ensure all appropriate headers are included.
