First set of new device support, features and cleanup for IIO in the 5.1 cycle
A number of interesting new devices supported plus a good set of staging
cleanup including one graduation and one drop.
New device support
* ad56886
- Add support for AD5674R/AD5679R with some minor driver changes to support
more channels.
* ad7768
- New driver and dt bindings for this 24 bit ADC.
* max44009
- New driver and dt bindings for this ambient light sensor.
* mpu6050
- Support the ICM 20602 IMU. Minor tweaks due to slightly different
register map.
* NPCM adc
- New driver and dt bindings for this BMC ADC.
* Sensiron SGP30
- Modifiers for ethanol and H2.
- New driver and dt bindings.
- Follow patch added self cleaning support.
* Sensiron SPS30
- New channel type for mass concentration.
- New driver and bindings.
- Minor tidy up patch followed (drop fmt specifier as unused)
* st_pressure
- lps22hh support. ID plus information structures and dt bindings.
* ti-ads124s08
- Add binding doc and driver.
Staging graduations
* ad7606 driver and bindings.
Staging drops
* ad7152 CDC driver dropped. This part is near EoL and no one is known
to be using it. If anyone surfaces obviously we can bring the driver
back. If not, good to drop it to avoid wasting anyone's time cleaning
it up.
New features
* bme680
- DT support and bindings doc.
* isl29018
- Add regulator for VCC.
* mag3110
- Add regulators for supplies.
* meson-saradc
- Support the temperature sensors of more SoCs.
* mma8452
- Add regulators for power suplies and binding docs to reflect them.
* st-accel
- Support the undocumented but it seems fairly common _ONT ACPI method
to specify orientation of the sensor.
Cleanup, minor fixes and fixes for staging driver that have been broken a
long time
* ad5933
- Drop platform data alternative to specifying the reference voltage
using a regulator.
- Use the clock framework to contorl the reference clock.
- Add a DT binding doc to cover the defacto binding.
* ad7280a
- Split up some big functions to improve readability.
* ad7606
- Allow for timeout if interrupt never occurs.
- Use devm functions to simplify probe and remove.
- Use the find_closest macro to avoid need for precise values from
userspace.
- Add missing vendor prefixes for various DT properties. Note the
driver is in staging still and there are no known devicetrees.
- Add explict OF device ID table.
- Simplify the Kconfig choices
- Change to a threaded IRQ.
- SPDX and simple stype fixes.
* ad7816
- Drop unnecessary variable init.
* ad9523
- Check a return value that was ignored.
* ad9833
- Drop platform data. It was just setting most values to the hardware
defaults.
- Use the clock framework to provide the input clock.
* adt7316 (lots of staging cleanup)
- Fix some wrong register / bit definitions
- Invert the logic of the check for an ldac pin so it actually makes sense.
- Read the right register to get internal vref settings
- Allow adt751x chips to use the internal vref for all DAC channels rather
than a subset.
- Remove dac vref bypass control from parts that don't have one.
- Make the store DAC update mode function consistent with the show one.
- Fix some spellings and other minor tidy up.
- Avoid passing irq numbers around by putting all the irq logic in
one place.
- Fix an issue with the resolution of DAC control.
- Fix support of the high resolution DAC mode (for temp proportional output)
where supported.
- Fix DAC read and write calculations.
* st_lsm6dsx
- Drop an unused variable (set but not read)
* xilinx-xadc
- Check an unhandled return value.

The ad7768-1 is a single channel, precision 24-bit analog to digital
converter (ADC).
This basic patch configures the device in fast mode, with 32 kSPS and
leaves the default sinc5 filter.
Two data conversion modes are made available. When data is retrieved by
using the read_raw attribute, one shot single conversion mode is set.
The continuous conversion mode is enabled when the triggered buffer
mechanism is used. To assure correct data retrieval, the driver waits
for the interrupt triggered by the low to high transition of the DRDY
pin.

iio: st_accel: use ACPI orientation data
Platform-specific ST accelerometer mount matrix information can be
provided by returning a package of 6 integers from the ACPI _ONT
method. This has been seen on Acer products such as Veriton Z4860G,
Z6860G and A890, which include a ST SMO8840 sensor. We have also
confirmed experimentally that the Windows driver uses such information.
The _ONT data format was explained by a ST vendor contact. However,
strangely enough, the _ONT transformations must be applied after first
applying another mount matrix which we determined experimentally. ST
have not commented on why this is the case, but we imagine that perhaps
earlier devices (before _ONT was introduced) required this translation
and hence it became 'standard.'
Interpret the _ONT data and export the equivalent mount matrix to
userspace.
If no _ONT data is present, no mount matrix is exported.

* avoid trying to operate TDLS when not connection,
this is not valid and led to issues
* count TTL-dropped frames in mesh better

KVM: VMX: Move vmx_vcpu_run()'s VM-Enter asm blob to a helper function
...along with the function's STACK_FRAME_NON_STANDARD tag. Moving the
asm blob results in a significantly smaller amount of code that is
marked with STACK_FRAME_NON_STANDARD, which makes it far less likely
that gcc will split the function and trigger a spurious objtool warning.
As a bonus, removing STACK_FRAME_NON_STANDARD from vmx_vcpu_run() allows
the bulk of code to be properly checked by objtool.
Because %rbp is not loaded via VMCS fields, vmx_vcpu_run() must manually
save/restore the host's RBP and load the guest's RBP prior to calling
vmx_vmenter(). Modifying %rbp triggers objtool's stack validation code,
and so vmx_vcpu_run() is tagged with STACK_FRAME_NON_STANDARD since it's
impossible to avoid modifying %rbp.
Unfortunately, vmx_vcpu_run() is also a gigantic function that gcc will
split into separate functions, e.g. so that pieces of the function can
be inlined. Splitting the function means that the compiled Elf file
will contain one or more vmx_vcpu_run.part.* functions in addition to
a vmx_vcpu_run function. Depending on where the function is split,
objtool may warn about a "call without frame pointer save/setup" in
vmx_vcpu_run.part.* since objtool's stack validation looks for exact
names when whitelisting functions tagged with STACK_FRAME_NON_STANDARD.
Up until recently, the undesirable function splitting was effectively
blocked because vmx_vcpu_run() was tagged with __noclone. At the time,
__noclone had an unintended side effect that put vmx_vcpu_run() into a
separate optimization unit, which in turn prevented gcc from inlining
the function (or any of its own function calls) and thus eliminated gcc's
motivation to split the function. Removing the __noclone attribute
allowed gcc to optimize vmx_vcpu_run(), exposing the objtool warning.
Kudos to Qian Cai for root causing that the fnsplit optimization is what
caused objtool to complain.

ibmveth: Do not process frames after calling napi_reschedule
