A namespace for exported symbols makes clear who is a provider
and who is a consumer of the certain resources. Besides that,
it doesn't pollute the common namespace.

Merge tag 'staging-5.13-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/staging

Pull staging/IIO driver updates from Greg KH:
"Here is the big set of staging and IIO driver updates for 5.13-rc1.

Lots of little churn in here, and some larger churn as well. Major
things are:

- removal of wimax drivers, no one has this hardware anymore for this
failed "experiment".

- removal of the Google gasket driver, turns out no one wanted to
maintain it or cares about it anymore, so they asked for it to be
removed.

- comedi finally moves out of the staging directory into drivers/comedi

This is one of the oldest kernel subsystems around, being created
in the 2.0 kernel days, and was one of the first things added to
drivers/staging/ when that was created over 15 years ago.

It should have been moved out of staging a long time ago, it's well
maintained and used by loads of different devices in the real world
every day. Nice to see this finally happen.

- so many tiny coding style cleanups it's not funny.

Perfect storm of at least 2 different intern project application
deadlines combined to provide a huge number of new contributions in
this area from people learning how to do kernel development. Great
job to everyone involved here.

There's also the normal updates for IIO drivers with new IIO drivers
and updates all over that subsystem.

All of these have been in linux-next for a while with no reported
issues"

1st set of IIO/counter device support, features and cleanup in the 5.13 cycle

Big set in here from Alexandru Ardelean enabling multiple buffer support.
This includes providing a new directory per buffer that combines
what was previously in buffer/ and scan_elements/. Old interfaces still
in place for compatiblity.

Note immuatable branch for scmi patches to allow for some significant
rework going on in that subsystem. Merge required updating to reflect
some changes in IIO.

Late rebase to fix some wrong fixes tags due to some earlier rebases
made necessary by messing up the immutable branch.

IIO New Device Support
* adi,ad5686
- Add info to support AD5673R and AD5677R
* bosch,bmi088
- New driver supporting this accelerometer + gyroscope
* cros_ec_mkbp
- New driver for this proximity sensor that exposes a 'front'
sensor. Very simple switch like device, but driver allows it
to share interface with more sophisticated proximity sensors.
* iio_scmi
- New driver to support ARM SCMI protocol to expose underlying
accelerometers and gyroscopes via this firmware interface.
* st,st_magn
- Add ID for IISMDC magnetometer.
* ti,ads131e0
- New driver supporting ads131e04, ads131e06 and ads131e08 24 bit ADCs

Counter New Device Support
* IRQ or GPIO based counter
- New driver for a conceptually simple counter that uses interrupts
to perform the count.

Features
* core
- Dual buffer supprt including:
Various helpers to centralize handling of bufferer related elements.
Document existing and new IOCTLs
Register the IIO chrdev only if it can actually be used for anything.
Rework attribute group creation in the core (lots of patches)
Merge buffer/ and scan_elements/ entries into one list + maintain
backwards compatible set.
Introduce the internal logic and IOCTL to allow multiple buffers
+ access to an anon FD per buffer to actually read from it.
Tidy up tools/iio/iio_generic_buffer and switch to new interfaces.
Update ABI docs.
A few follow up fixes, unsuprising as this was a huge bit of rework.
- Move common case setting of trig->parent to the core.
- Provide an iio_read_channel_processed_scale() to avoid loss of
precision from iio_read_channel_processed() then applying integer
scale. Use it in ntc_thermistor driver in hwmon.
- Allow drivers to specify labels from elsewhere than DT. Use it for
bmc150 and kxcjk-1013 labels related to position on 2 in one tablets.
- Document label usage for proximity and accelerometer sensors.
- Some local variable renames for consistency
tools
- Add -a parameter to iio_event_monitor to allow autoenabling of events.
* acpi_als
- Add trigger support for devices that don't support notification method.
* adi,ad7124
- Allow more than 8 channels. This is a complex little device, but is
capable of supporting up to 16 channels if the share certain
configuration settings.
* hrtimer-trigger
- Support sampling frequency below 1Hz.
* mediatek,mt8195-auxadc
- Add compatible to binding docs (always also includes mt8173)
* st,stm32-adc
- Enable timetamps when not using DMA.
* vishay,vcnl3020
- Sampling frequency control.

Cleanup and minor fixes:
* treewide
- Use some getter and setter functions instead of opencoding.
- Set of fixes for pointless casts in various drivers.
- Avoid wrong kernel-doc marking on comment blocks.
- Fix various other minor kernel-doc issues shown by W=1
* core
- Use a signed temporary for IIO_VAL_FRACTIONAL_LOG2 to avoid odd casts.
- Fix IIO_VAL_FRACTIONAL_LOG2 for values between -1.0 and 0.0
- Add unit tests for iio_format_value()
* docs
- Fix formatting/typos in iio_configfs.rst and buffers.rst
- Add documentation of index in buffers.rst
- Fix scan element description
- Avoid some issues with HTML generation from ABI docs by moving
duplicated defintions to more generic files.
- Drop reference to long dead mailing list.
* 104-quad
- Remove left over deprecated IIO counter ABI.
* adi,adi-axi-adc
- Fix wrong bit of docs.
* adi,ad5791
- Typos
* adi,ad9834
- Switch to device managed functions in probe.
* adi,adis*
- Add and use helpers for locking to reduced duplication.
* adi,adis16480
- Fix calculation of sampling frequency when using pulse per second input.
* adi,adis16475
- Calculate the IMU scaled internal sampling rate and runtime depending
on sysfs based configuration rather than getting from DT. Drop now
unnecessary property from DT bindings doc.
* cros_ec
- Fix result of a series of recent changes that means extended buffer
attributes turn up in the wrong place. Too complex to revert the
various patches unfortunately so this is a bit messy.
* fsl,mma3452
- Indentation cleanup.
* hid-sensors
- Size of storage needs to increase for some parts when using quaternions.
- Move the get sensistivity attribute to hid-sensors-common to reduce
duplication. Enable it for more device types.
- Correctly handle relative sensitivity if reported that way including
documenting the new ABI.
* maxim,max517
- Use device managed functions in probe.
* mediatek,mt6360-adc
- Use asm/unaligned.h instead of directly including
unaligned/be_byteshift.h
* novuton,npcm-adc
- Local lock instead of missusing mlock.
* semtech,sx9500
- Typos
* st,sensor
- typo fix
* st,spear-adc
- Local lock instead of missusing mlock.
* st,stm32-adc
- Long standing HAS_IOMEM dependency fix.
* st,stm32-counter

iio: hid-sensors: Move get sensitivity attribute to hid-sensor-common

No functional change has been made with this patch. The main intent here
is to reduce code repetition of getting sensitivity attribute.

In the current implementation, sensor_hub_input_get_attribute_info() is
called from multiple drivers to get attribute info for sensitivity
field. Moving this to common place will avoid code repetition.

"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

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)
