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.
asahi-kasei,ak8975
- Drop a prefix free compatible accidentally added recently.
aspeed,adc
- Use of_property_present() instead of of_find_property() to see if the
  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.

In commit 0f718e10 ("iio: ABI: add missing calibbias attributes"),
the in_resistance_calibbias attribute was added to the main IIO ABI
documentation. This attribute is was already documented in
sysfs-bus-iio-chemical-sgp40. This resulted in a duplicate entry that is
causing documentation build warnings.

This removes the attribute from the sgp40 documentation in favor of the
main IIO ABI documentation since this attribute fits the established
pattern of standard IIO attributes.

fuse_notify_store(), unlike fuse_do_readpage(), does not enable page
zeroing (because it can be used to change partial page contents).

So fuse_notify_store() must be more careful to fully initialize page
contents (including parts of the page that are beyond end-of-file)
before marking the page uptodate.

The current code can leave beyond-EOF page contents uninitialized, which
makes these uninitialized page contents visible to userspace via mmap().

This is an information leak, but only affects systems which do not
enable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the
corresponding kernel command line parameter).

 - New on disk format version, bcachefs_metadata_version_disk_accounting_inum

   This adds one more disk accounting counter, which counts disk usage
   and number of extents per inode number. This lets us track
   fragmentation, for implementing defragmentation later, and it also
   counts disk usage per inode in all snapshots, which will be a useful
   thing to expose to users.

 - One performance issue we've observed is threads spinning when they
   should be waiting for dirty keys in the key cache to be flushed by
   journal reclaim, so we now have hysteresis for the waiting thread, as
   well as improving the tracepoint and a new time_stat, for tracking
   time blocked waiting on key cache flushing.

This implements buffered reads for the ad4695 driver using the typical
triggered buffer implementation, including adding a soft timestamp
channel.

The chip has 4 different modes for doing conversions. The driver is
using the advanced sequencer mode since that is the only mode that
allows individual configuration of all aspects each channel (e.g.
bipolar config currently and oversampling to be added in the future).

The current code is always iterating over two fields in the
noa1305_int_time_available array. Fix iteration limit, which
has to be halved to avoid out of bounds access in case the
value that is being looked up is not in the array.

Although there are several patches improving the extent map shrinker,
there are still reports of too frequent shrinker behavior, taking too
much CPU for the kswapd process.

So let's only enable extent shrinker for now, until we got more
comprehensive understanding and a better solution.
