KVM/arm64 fixes for 6.12, take #1

- Fix pKVM error path on init, making sure we do not change critical
system registers as we're about to fail

- Make sure that the host's vector length is at capped by a value
common to all CPUs

- Fix kvm_has_feat*() handling of "negative" features, as the current
code is pretty broken

- Promote Joey to the status of official reviewer, while James steps
down -- hopefully only temporarly

A bunch of fixes here that came in during the merge window and the first

major here, it's a bit bigger than it might've been due to there being

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.

spi: Enable controllers to extend the SPI protocol with MOSI idle configuration

The behavior of an SPI controller data output line (SDO or MOSI or COPI
(Controller Output Peripheral Input) for disambiguation) is usually not
specified when the controller is not clocking out data on SCLK edges.
However, there do exist SPI peripherals that require specific MOSI line
state when data is not being clocked out of the controller.

Conventional SPI controllers may set the MOSI line on SCLK edges then bring
it low when no data is going out or leave the line the state of the last
transfer bit. More elaborated controllers are capable to set the MOSI idle
state according to different configurable levels and thus are more suitable
for interfacing with demanding peripherals.

Add SPI mode bits to allow peripherals to request explicit MOSI idle state
when needed.

When supporting a particular MOSI idle configuration, the data output line
state is expected to remain at the configured level when the controller is
not clocking out data. When a device that needs a specific MOSI idle state
is identified, its driver should request the MOSI idle configuration by
setting the proper SPI mode bit.

Pull driver core updates from Greg KH:
"Here is the big set of driver core changes for 6.11-rc1.

Lots of stuff in here, with not a huge diffstat, but apis are evolving
which required lots of files to be touched. Highlights of the changes
in here are:

- platform remove callback api final fixups (Uwe took many releases
to get here, finally!)

- Rust bindings for basic firmware apis and initial driver-core
interactions.

It's not all that useful for a "write a whole driver in rust" type
of thing, but the firmware bindings do help out the phy rust
drivers, and the driver core bindings give a solid base on which
others can start their work.

There is still a long way to go here before we have a multitude of
rust drivers being added, but it's a great first step.

- driver core const api changes.

This reached across all bus types, and there are some fix-ups for
some not-common bus types that linux-next and 0-day testing shook
out.

This work is being done to help make the rust bindings more safe,
as well as the C code, moving toward the end-goal of allowing us to
put driver structures into read-only memory. We aren't there yet,
but are getting closer.
