w1: ds2482: Drop explicit initialization of struct i2c_device_id::driver_data to 0
This driver doesn't use the driver_data member of struct i2c_device_id,
so don't explicitly initialize this member.
This prepares putting driver_data in an anonymous union which requires
either no initialization or named designators. But it's also a nice
cleanup on its own.

Foxconn uses a unique firmware for their MHI based modems. So the generic

include the 'foxconn' subdirectory based on the modem SoC so that the
Foxconn specific firmware could be used.
Respective firmware will be upstreamed to linux-firmware repo.

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.

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

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

the in_resistance_calibbias attribute was added to the main IIO ABI

sysfs-bus-iio-chemical-sgp40. This resulted in a duplicate entry that is
causing documentation build warnings.
This removes the attribute from the sgp40 documentation in favor of the
main IIO ABI documentation since this attribute fits the established
pattern of standard IIO attributes.

vice versa.
Now that Perf uses its own exclusive ID maps, pending release doesn't
result in any different behavior than just releasing all IDs when the
last Perf session finishes. As part of the per-sink trace ID change, we
would have still had to make the pending mechanism work on a per-sink
basis, due to the overlapping ID allocations, so instead of making that
more complicated, just remove it.

coresight: Use per-sink trace ID maps for Perf sessions
This will allow sessions with more than CORESIGHT_TRACE_IDS_MAX ETMs
as long as there are fewer than that many ETMs connected to each sink.
Each sink owns its own trace ID map, and any Perf session connecting to
that sink will allocate from it, even if the sink is currently in use by
other users. This is similar to the existing behavior where the dynamic
trace IDs are constant as long as there is any concurrent Perf session
active. It's not completely optimal because slightly more IDs will be
used than necessary, but the optimal solution involves tracking the PIDs
of each session and allocating ID maps based on the session owner. This
is difficult to do with the combination of per-thread and per-cpu modes
and some scheduling issues. The complexity of this isn't likely to worth
it because even with multiple users they'd just see a difference in the
ordering of ID allocations rather than hitting any limits (unless the
hardware does have too many ETMs connected to one sink).

coresight: Make CPU id map a property of a trace ID map
The global CPU ID mappings won't work for per-sink ID maps so move it to
the ID map struct. coresight_trace_id_release_all_pending() is hard
coded to operate on the default map, but once Perf sessions use their
own maps the pending release mechanism will be deleted. So it doesn't
need to be extended to accept a trace ID map argument at this point.

btrfs: only enable extent map shrinker for DEBUG builds
