"Here is the large set of staging and IIO driver updates for 5.10-rc1.

Included in here are:

- new IIO drivers

- new IIO driver frameworks

- various IIO driver fixes and updates

- IIO device tree conversions to yaml

- so many minor staging driver coding style cleanups

- most cdev driver moved out of staging

Second set of features and cleanups for IIO in 5.10

We have a couple of changes that apply to large sets of drivers, so
I have grouped those to keep this short.

There are a few late breaking fixes in here that can wait for the
merge window.

trigger. Includes updating bindings.
- Add debugfs hooks for register access.
* mlx90632
- Add a clear user interface to override the measured ambient temperature.

Cleanups and minor fixes
------------------------
(groups)
Replace mlock with local lock:

* exynos-adc
* fls-imx25-gcq

of_match_ptr removal and incorrect ACPI binding removal
of_match_ptr() rarely makes sense in an IIO driver as space saving
is trivial and it breaks ACPI PRP0001 based instantiation.
Mostly this series is about removing examples that get copied into new
drivers.

iio: gyro: adxrs290: Add triggered buffer support

Provide a way for continuous data capture by setting up buffer support. The
data ready signal exposed at the SYNC pin of the ADXRS290 is exploited as
a hardware interrupt which triggers to fill the buffer.

Triggered buffer setup was tested with both hardware trigger (DATA_RDY) and
software triggers (sysfs-trig & hrtimer).

First set of new device support, features and cleanup for IIO in 5.10 cycle, take 2

A few changes to how I write this cover letter.
* Started to use manufacturer prefixes to group changes better.
* Stop list minor formatting etc changes.
* Whilst I appreciate those changes, we don't need to call them out here.

New device support:
* adi,adxrs290
- New driver for this gyroscope with dt bindings. One fix follows.
* ams,as73211
- New driver for this colour sensor with dt bindings. Also includes
docs for XYZ modifiers as used for the CIE colour space. Sysfs docs.
* atlas,atlas-ezo-sensor
- Support O_2 sensor, includes new modifier for concentration.
- Support humidity sensor.
* ti,hdc2010
- New driver support hdc2010 and hdc2080 humidity sensors. Includes dt
bindings.

Cleanup, minor fixes and features
* core
- Make the trigger related stub functions static inline, avoiding some build
warnings.
- buffer-dmaengine. Allow adjusting bytes_used with residue info.
* dev_error_probe to replace open coded equivalent in many drivers.
* docs and comment fixes
- Fix some typos, doubled words, capitalisation and punctuation.
* dt binding conversions to yaml
- lltc,ltc2497
- lltc,ltc2632
- maxim,max11100
- maxim,max1118
- maxim,max9611
- microchip,mcp3201
- microchip,mcp342x (add to trivial devices)
- ti,adc0832
- ti,adc108s102
- ti,adc128s052
- ti,adc161s626
- ti,ads8344
- ti,tlc4541 (includes adding an accidentally dropped original binding doc)
* adi,adi-axi-adc
- Use kobj_to_dev instead of open coding.
* adi,ad5686
- Constify iio_chan_spec
* adi,ad8366
- Add HMC1119 to kconfig help text as the driver supports it.
* adi,ad9523
- Use devm for reset of probe and drop remove.
* adi,adxl372
- Tidy up alignment
- Add OF table
- Add peak mode support with some docs.
* bosch,bma220 (general tidy up)
- Fix some return codes.
- Use read_avail callback rather than open coding attrs.
- Use dev_get_drvdata rather than dance via to_spi_device()
- Mark PM functions as __maybe_unused rather than #ifdef fun.
- Drop ACPI_PTR protections and ifdefs.
- Tidy up header ordering.
- BIT and GENMASK
* broadcom,bcm_iproc
- Drop of_match_ptr protection and switch to mod_devicetable.h
Part of general move to get this anti-pattern out of IIO.
* melexis,mlx90614
- Simplify some calculations.
- Add some kernel_doc
- Use regmap poll loop rather than open coding.
- Add extended calibration option.
* sensortec,sx9310, wide ranging set of fixes and cleanups.

- Rename some macros to align better with spec sheet
- Fix some issues with irq handling.
- Drop of_match_ptr and ACPI_PTR macros to avoid unused warnings etc.
- Switch to probe_new

- Use long for bitmaps to allow use of for_each_bit_set()
- Use regmap_read_poll instead of opencoding.
- Simplify error paths
- Enabled regulators at probe.
- Use trigger flags from firmware rather than forcing them in the driver.
* ti,adc081c
- Drop ACPI IDs that are not likely to be official ones and we don't believe
anyone is using.
* ti,adc108s102
- Drop CONFIG_OF and of_match_ptr protections.
* ti,adc128s052
- Drop of_match_ptr protection and include mod_devicetable.h
* ti,dac5571
- Support powerdown for mutlichannel usecases.
* xpowers,axp20x
- Convert from OF to generic fw / device properties. Unlikely anyone will
use this with anything other than devicetree, but this is part of a
general move across IIO.
