A device bound through driver_override need not match an entry in the
driver tables. In that case spi_get_device_match_data() returns NULL,
but the result is later dereferenced by the property parsing and
initialization paths.
Reject devices without match data before continuing probe.

Add OSK channel with amplitude envelope control capabilities:
- OSK enable/disable via IIO_CHAN_INFO_ENABLE;
- Amplitude ramp rate control via IIO_CHAN_INFO_SAMP_FREQ;
- Amplitude scale factor readback via IIO_CHAN_INFO_RAW (ASF register);
- Automatic OSK step size configurable through the raw_roc extended
attribute, which allows for selectable step sizes in raw units:
- 0: no step, means manual mode (NOT pin controlled)
- 1: I_FS / 2^14 step, automatic mode (pin controlled)
- 2: 2 I_FS / 2^14 step, automatic mode (pin controlled)
- 4: 4 I_FS / 2^14 step, automatic mode (pin controlled)
- 8: 8 I_FS / 2^14 step, automatic mode (pin controlled)
- 16383: I_FS step (max), manual mode (pin controlled)
The ASF register is initialized with a default amplitude ramp rate during
device setup to ensure valid readback.

Add RAM control channel, which includes:
- RAM data loading via firmware upload interface;
- Per-profile configuration and DDS core parameter destination as firmware
metadata;
- Profile switching relying on profile channels;
- Sampling frequency control of the active profile;
- ram-enable-aware read/write paths that redirect single tone
frequency/phase/amplitude access through reg_profile cache when RAM is
active;
When RAM is enabled, the DDS profile parameters (frequency, phase,
amplitude) for the single tone mode are sourced from a shadow register
cache (reg_profile[]) since the profile registers are repurposed for RAM
control.

Add parallel port support with amplitude, phase and frequency channels.
Those will be buffered capable channels, but only basic control of offset
and scale are implemented at this point. There are separate amplitude
and phase control for polar destination, which will provide different scan
types. Enabling and disabling of parallel mode will be implemented with
buffer setup ops or with update_scan_mode() once IIO backend integration

The clk_init_data structure contains several mutually-exclusive members
for different methods to specify the possible parents of a clock,
prompting drivers to initialize only the members they need. However,
not initializing all members may cause subtle issues, which are only
exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is
enabled.
Make sure all members are fully initialized, to avoid such bugs, and to
prevent future breakage when converting drivers to a different method
for specifying the parents.

admv1013_read_raw() switches on chan->channel instead of
chan->channel2 when handling IIO_CHAN_INFO_CALIBBIAS. The channel
field only ever holds 0 or 1 (see ADMV1013_CHAN_CALIB()), while the
IIO_MOD_I / IIO_MOD_Q modifiers are stored in channel2. As a result,
the switch always falls through to the default case and calibbias
reads always fail with -EINVAL, even though the corresponding
admv1013_write_raw() path correctly uses channel2 and works as
expected.
Fix the read path to switch on chan->channel2, matching the write
path and the actual channel_spec definition.

admv1013_probe() registers a clock notifier whose callback takes st->lock
on POST_RATE_CHANGE. Initialize the mutex before
devm_clk_notifier_register() so the callback cannot observe an
uninitialized lock during probe.
Use devm_mutex_init() so the lock lifetime is tied to the device and
cleanup stays paired with the rest of the managed probe resources.

not initializing all members may cause subtle issues, which are only
exposed when CONFIG_INIT_STACK_ALL_PATTERN or CONFIG_INIT_STACK_NONE is

adf4377_clk_register() fills in init.parent_data, and assumes that
init.parent_names is NULL. However, the latter is uninitialized, and
thus may cause a crash.
Similarly, adf4377_clk_register() fills in only parent_data.fw_name,
leaving other members of the clk_parent_data structure uninitialized.
Make sure all members are fully initialized, to fix such bugs, and to
avoid future breakage when converting drivers to a different method for

While being less compact, using named initializers allows to more easily
see which members of the structs are assigned which value without having
to lookup the declaration of the struct. And it's also more robust
against changes to the struct definition.
The mentioned robustness is relevant for a planned change to struct
spi_device_id that replaces .driver_data by an anonymous union.
This patch doesn't modify the compiled arrays, only their representation
in source form benefits. The former was confirmed with x86 and arm64

Replace manual mutex_lock()/mutex_unlock() calls with guard(mutex)() from
cleanup.h.
Using guard(mutex)() from cleanup.h allows the compiler to enforce lock
release on every exit path, eliminating the error-prone manual lock/unlock
pattern and the goto-based exit labels that existed in adf4377_get_freq()
and adf4377_set_freq(). This reduces the chance of lock imbalance bugs.

The ADRF6780 datasheet (Rev. D, page 23, ADC section) says:
"Wait approximately 200 us for the ADC to be ready."
fsleep(200) expands to the same usleep_range(200, 250). Use the
flexible sleep helper, which picks the right primitive for the
given microsecond delay.
Replace the generic "Recommended delay for the ADC to be ready"
comment with the datasheet reference so the "why" of the wait is

The regmap_read_poll_timeout() uses ADF4377_0000_SOFT_RESET_R_MSK
twice instead of checking both SOFT_RESET_MSK (bit 0) and
SOFT_RESET_R_MSK (bit 7). This causes an incomplete reset status check.
The code first sets both SOFT_RESET and SOFT_RESET_R bits to 1 via
regmap_update_bits(), then polls for them to be cleared. Since we set
both bits before polling, we should be waiting for both to clear.
Fix by using both masks as done in regmap_update_bits() above.

Features
========
Core
- New helper to multiply data expressed in IIO types.

- New IIO_ALTCURRENT type, similar to existing IIO_ALTVOLTAGE
- Add some channel modifiers related to energy and power, such as
reactive.

- Add backend support which required control of the number of lanes used.
liteon,ltr390
- Add runtime PM support.
microchip,mcp9600
- Add support for different thermocouple types.
Cleanup and minor fixes
=======================
core
- Switch info_mask fields to be unsigned. Not clear why they were ever
signed.
- Fix handling of negative channel scale in iio_convert_raw_to_processed()
- Fix offset handling for channels without a scale attribute.
- Improve the precision of scaling slightly.
- Drop apparent handling of IIO_CHAN_INFO_PROCESSED for devices that don't
have any such channels.
various
- Drop many pm_runtime_mark_last_busy() calls now
pm_runtime_put_autosuspend() calls it internally.
- Drop dev_err_probe() calls where the error code is hard coded as -ENOMEM
as they don't do anything.
- Drop dev_err() calls where the error code is -ENOMEM. This will reduce
error prints, but memory failures generate a lot of messages anyway
so unlikely we need these prints.
current-sense-amplifier
- Add #io-channels property this channel to be used by a consumer driver.
adi,ad7124
- Fix incorrect clocks dt-binding property.
- Make the mclk clock optional in DT - this is internal to the ADC so should
never have been in he binding.
- Fix up sample rate to comply with ABI.
- Use read_avail() callback rather than opencoding similar.
- Deploy guard() to clean up some lock handling.
adi,ad7768
- Use devm_regulator_get_enable_read_voltage() to replace similar code.
adi,ad7816
- Drop an unnecessary dev_set_drvdata() call as nothing uses the data.
ad,adxl345
- Fix missing blank line before bullet list in documentation.
arm,scmi
- Use devm_kcalloc() for an array allocation rather than devm_kzalloc().
bosch,bmi270
- Match an ACPI ID seen in the wild. It is not spec compliant but we can't
do much about that.
bosch,bmp280
- Drop overly noisy dev_info()
- Allow for sleeping gpio controllers.
gogle,cros-ec
- Drop unused location attribute that has been replaced by label.
invense,icm42600
- Simplify the power management.
- Use guard() to simplify some locking.
maxim,max1238
- Add io-channel-cells property to dt-binding as there is an in tree
consumer.
microchip,mcp9600
- Specify a default value in dt-binding for the thermocouple type
- General whitespace cleanup.
samsung,exynos
- Drop support for the S3C2410 including bindings, and touchscreen support
as nothing else uses that.
- Drop platform ID based binding as not used.
st,vl53l0x
- Fix returning the wrong variable in an error path.
ti,pac1934
- Replace open coded devm_mutex_init().
xilinx,ams
- Update maintainers entry.

The ADF4350/1 features a programmable dual-modulus prescaler of 4/5 or 8/9.
When set to 4/5, the maximum RF frequency allowed is 3 GHz.
Therefore, when operating the ADF4351 above 3 GHz, this must be set to 8/9.
In this context not the RF output frequency is meant
- it's the VCO frequency.
Therefore move the prescaler selection after we derived the VCO frequency
from the desired RF output frequency.
This BUG may have caused PLL lock instabilities when operating the VCO at
the very high range close to 4.4 GHz.

When `devm_add_action_or_reset()` fails, it is due to a failed memory
allocation and will thus return `-ENOMEM`. `dev_err_probe()` doesn't do
anything when error is `-ENOMEM`. Therefore, remove the useless call to
`dev_err_probe()` when `devm_add_action_or_reset()` fails, and just
return the value instead.

The variable ret is being assigned a return value and non-zero error
return paths are taken at all stages. At the end of the function ret
is always zero, so the ternary operator checking for zero ret is
redundant and can be replaced with just len instead.

Use `\t(\{ ?\},|\{\}|\{\s*/\*.*\*/\s*\},?)$` regex to find and replace
the array sentinel in all IIO drivers to the same style.
For some time, we've been trying to consistently use `{ }` (no trailing
comma, no comment, one space between braces) for array sentinels in the
IIO subsystem. Still nearly 50% of existing code uses a different style.
To save reviewers from having to request this trivial change as
frequently, let's normalize the style in all existing IIO drivers.
At least when code is copy/pasted to new drivers, the style will be
consistent.
