There is some inconsistency and whitespace cleanup performed in this
patch. It was done on top of my other patches, but I can rebase to head
of the togreg branch if it would go in sooner.

iio:temperature:mlx90632: Adding extended calibration option

For some time the market wants medical grade accuracy in medical range,
while still retaining the declared accuracy outside of the medical range
within the same sensor. That is why we created extended calibration
which is automatically switched to when object temperature is too high.

This patch also introduces the object_ambient_temperature variable which
is needed for more accurate calculation of the object infra-red
footprint as sensor's ambient temperature might be totally different
than what the ambient temperature is at object and that is why we can
have some more errors which can be eliminated. Currently this temperature
is fixed at 25, but the interface to adjust it by user (with external
sensor or just IR measurement of the other object which acts as ambient),
will be introduced in another commit.

"Here is the large set of Staging and IIO driver patches for 5.9-rc1.

Lots of churn here, but overall the size increase in lines added is
small, while adding a load of new IIO drivers.

Major things in here:

- lots and lots of IIO new drivers and frameworks added

- IIO driver fixes and updates

- lots of tiny coding style cleanups for staging drivers

- vc04_services major reworks and cleanups

We had 3 set of drivers move out of staging in this round as well:

- wilc1000 wireless driver moved out of staging

- speakup moved out of staging

- most USB driver moved out of staging

Full details are in the shortlog.

All of these have been in linux-next with no reported issues. The last
few changes here were to resolve reported linux-next issues, and they
seem to have resolved the problems"

Second set of new device support, cleanups etc for IIO/Counters in the 5.9 cycle

There are two merge commits in here of immutable branches that may
also be picked up through other trees (clocksource and input)

I've put a few late breaking fixes in here that aren't worth rushing
in before the merge window. One major fix for an issue introduced
in the last set that can result in devices not having their parent set.

This set is dominated by W=1 cleanups from Lee Jones. I won't list them
all separately. They are mostly:
* Kernel doc fixes
* Unused variable removal.
* Suppression of unused stuff that is static in headers.

Counters subsystem
* atmel-tcb
- New counter driver after various cleanups of existing tcb code and bindings.

Device support
* stk311
- Trivial addition of ID for STK311-X variant.

yaml conversions
* kionix,kxsd9
* ti,ads8688

Features
* jz47xx
- Add support for touch screen channels. In this particular case the
boards in question actually wire a joystick to them so we want them
as simple voltage channels. The joystick driver will probably go
via the input tree.

Cleanups + fixes
* core
- A rebase issue in recent major refactoring dropped the assignment of
of the device parent in the core. Put it back.
* ad5592r
- Fix unbalanced mutex unlocks in *_read_raw()
* ad7124
- Move chip ID and name to the chip_info table plus add a read of the
revision register to check the device is working during probe.
* ad7192
- Ridy up ordering to put the match table near the end fo the file where it
is used.
* lsm6dsx
- Reset the hardware timestamp after a resume to avoid an issue with
missaligned timestamps after suspend.
* jz47xx
- Error checks on clk_enable() calls.
- xlate callaback to find channel index.
- Use separate chan_spec arrays for different variants rather than
parts of a single list. Simplifies code.

First set of new device support, cleanups and features for IIO in the 5.9 cycle

Some new devices, but particularly good this time is the core rework coming
from Alexandru. Some of this has been in Analog's tree a long time, but other
parts are motivated by closing down common mistakes in new drivers.

Changes since first try at this pull request:
* Add missed patch to actually remove iio_priv_to_dev and as a result
also drop a few ingenic patches that need to be updated to take this
into account.
* Fix an ordering issue int he pollfunc attach in the core rework.

New device support
* qcom pmic7 adc
- New driver using common qcom-vadc library. Some associated cleanups and
refactors.
* invensense icm42600
- New driver supporting icm42600, icm42602, icm42605 and icm42622 via i2c
or spi. These are all 6 axis IMUs with gyro and accelerometers.
Driver supports buffered modes using the hardware fifo and interpolation
for accurate timestamps.
* sensirion scd30
- New driver for this carbon dioxide sensor including i2c and serial
interfaces + bindings.

Features
* ak8975
- Add reset gpio support.
* bma400
- Support SPI.
* bmc150
- Document and add support for bmc156b and bmm150b, tidy up _magn endings.
* bmi160
- Regulator and mount matrix support.
* mxc4005
- Add ID for mxc6655
* rockchip-saradc
- Triggered buffer support.

DT bindings
* qcom spmi-vadc converted to yaml + pmic7 bindings
* ak8975 tidy up and convert to yaml + add reset-gpio binding
* ingenic-adc -convert to yaml.

Core rework all carried through by Alexandru Ardelean.
* Assign parent device in the core rather than every driver. A few devices
need to provide specific non standard parents, so there is support for
overriding.
* Start to take parts of struct iio_dev opaque to the drivers.
This will be a long term job, but should reduce the number of drivers
we get that use parts that are currently only 'internal' by documentation.
* Move attach and detach of pollfunc to the core. Every triggered buffer
using driver had to do the same thing, so lets do it in the core. The
hard part here was getting all the drivers into canonical form so there
would be no functional changes in this final patch. That's taken quite
a lot of work over last couple of cycles!

Cleanups and minor fixes.
* docs
- Improve IIO_CONCENTRATION channel type description in ABI docs.
- Drop doubled word cases.
- Http to Https conversion.
* core
- Make iio_device_get_drvdata take a const struct iio_dev * avoiding some
nasty casts.
* ADCs
- Drop lots of users of of_match_ptr macro, includes of mod_devicetable.h
and CONFIG_OF protections. These prevent use of ACPI PRP0001 with these
drivers and get coppied into lots of new drivers.
* ad5380
- Constify iio_chan_spec_ext_info
* ad5592r
- Constify iio_chan_spec_ext_info
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* ad8366
- Make gpio optional as doesn't matter if its there or not.
* adis16480
- Use irq types instead of the flags.
* atlas-ezo-sensor
- Minimize scope of ret variable.
* at91-adc
- Add COMPILE_TEST dependency to driver to improve build coverage.
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* at91-sama5d2
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
- Drop Ludovic as a co-maintaienr.
* cros_ec
- Reapply the range after resume.
- Add a read only frequency entry for legacy version.
- Typo fixes
* hts221
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* inv_mpu
- Drop double check on ACPI companion device.
* iqs621
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* iqs624
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* max11100
- Constify iio_chan_spec
* mmc35240
- Constify reg_default
* rockchip-saradc
- Move to managed allocators for everything in probe.
- Use more distinctive prefix for channel macros.
* stk3310
- Constify regmap_config.
* stm32-adc
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)
* stm32-dfsdm-adc
- Avoid use of iio_priv_to_dev (precursor to taking parts of iio_dev opaque)

It updates 302 files and does 307 deletions.
This semantic patch also removes some comments like
'/* Establish that the iio_dev is a child of the i2c device */'

But this is is only done in case where the block is left empty.

The patch does not seem to cover all cases. It looks like in some cases a
different variable is used in some cases to assign the parent, but it
points to the same reference.
In other cases, the block covered by ... may be just too big to be covered
by the semantic patch.

However, this looks pretty good as well, as it does cover a big bulk of the
drivers that should remove the parent assignment.
