Add a new driver for the TI ADS112C14/ADS122C14 ADC chips.
This first step is adding a very basic driver that only supports power
on/reset and reading the system monitor channels.
ADS112C14_SYS_MON_CHANNEL_SHORT is the last channel rather than being in
logical order by address to keep the voltage channels together and in
case we find we need to add variants of this channel with different
voltage reference later.

Add new bindings for ti,ads112c14 and similar devices.
This is an ADC that is primarily intended for use with resistive sensors
(RTD, thermocouple, Wheatstone bridge, etc.). There are a few unusual
properties because of this. In particular, the reference voltage source
and current output requirements can be different for each measurement,
so these are included in the channel bindings.
The REFP/REFN reference voltage is usually just connected to a resistor
that is being driven by the ADC's current outputs, so there is special
property for this case rather than requiring a regulator to be defined
to represent that.

Add a generic input-chopping property to adc.yaml. This is a feature
seen frequently in ADCs that are designed to measure resistive loads,
such as RTDs and strain gauges. Enabling this can reduce offset errors
by swapping the positive and negative input channels on every other
conversion. This can have side-effects in timing and filter response, so
it is not always desirable to enable this feature in some applications.
Therefore, it is best to make this a property that can be enabled or
disabled in the device tree.

Allow buffer blocks flagged as cyclic to be submitted as repeating DMA
transfers. For cyclic blocks, use DMA_PREP_REPEAT so the engine keeps
replaying the descriptor.
This is useful for output buffers where the same data should be driven
continuously without userspace having to requeue it. Examples include
continuous RF transmit paths replaying a calibration, test or beacon
pattern.
Skip installing the completion callback for cyclic blocks. Since the
transfer is continuously replayed, the callback would fire on every
period, throwing off the block refcount.
Because nothing prevents a new cyclic transfer from replacing an
already active cyclic one, always set DMA_PREP_LOAD_EOT so the engine
correctly terminates the active transfer before loading the new
descriptor.
Limit the DMA buffer queue to one cyclic DMABUF at a time. There is
currently no known use case for queueing multiple cyclic blocks, and
cyclic blocks stay referenced until the buffer is disabled.

Most of the supported devices rely on a GAIN pin to control a 2x
multiplier applied to the output voltage. Other devices, e.g. the
single-channel ones, provides a gain control through a bit field in
the control register. Some designs might have the GAIN pin hardwired
to VDD/VLOGIC or GND, which would have no "gain-gpios" device property,
being able to set "adi,range-double" if it is hardwired to VDD. The
vref_mv field is moved down in the struct ad5686_state, so that the
overall size increase is reduced.

Use of local SPI bus data to manage a collection of SPI transfers and

allows for faster handling of multiple channel DAC writes, avoiding kernel

For the AD5310 regmap case, 16-bit data coming from the buffer may overlap
with command bits if the data field is unmasked.
*_REF_BIT_MSK and *_PD_MSK bit position macros are renamed (with a DATA

Running kernel-doc on the file emits 103 warnings:

Reading the in_accel_scale attribute on the DMARD09 has always returned
-EINVAL: the channels advertise scale via info_mask_shared_by_type so the
IIO core exposes the attribute, but dmard09_read_raw() only handles
IIO_CHAN_INFO_RAW, so a SCALE read falls through to 'default: return
-EINVAL':
$ cat .../iio:deviceX/in_accel_scale
cat: in_accel_scale: Invalid argument
leaving userspace with raw counts it cannot convert to m/s^2.
The driver was written from a vendor source [1] without a datasheet, and
the scale was declared but never implemented. The vendor source carries
the sensitivity: its conversion is
acc = raw * GRAVITY_EARTH_1000 / sensitivity (then / 1000 -> m/s^2)
with sensitivity = 32 and GRAVITY_EARTH_1000 = 9807 ("about
(9.80665)*1000"), i.e. 32 counts correspond to 1 g.
That sensitivity applies to the value this driver already reports as raw:
the vendor reduces each 16-bit sample to a signed 9-bit value, and the
preparation in dmard09_read_raw() yields the same value. It is
self-consistent: 256 counts / 32 = 8 g full scale, matching the +/-8g
range.
Implement the scale derived from that sensitivity using standard gravity:
scale = 9.80665 / 32 = 0.3064578125 m/s^2 per LSB

A small set of fixes that came in since -rc1, we have one core fix for
shutting down target mode properly if the system suspends while it's
running plus a small set of fairly unremarkable device specific fixes.
There's also a couple of pure DT binding changes for Renesas SoCs, the
power domains one allows some SoCs to be correctly described with
existing code.

Use namespaced exports for IIO consumer API functions.
This will make it easier to manage the IIO export surface. Consumer drivers
will only be provided access to a specific set of functions, thereby
restricting usage of internal IIO functions by other parts of the kernel.
This change cannot be split into several parts without breaking
bisectability, thus all of the affected drivers are modified at once.

The driver has an OF match table wired to .of_match_table, but does
not export the table with MODULE_DEVICE_TABLE().
Add the missing MODULE_DEVICE_TABLE(of, ...) entry so module alias
information is generated for OF based module autoloading.
This is a source-level fix. It does not claim dynamic hardware
reproduction; the evidence is the driver-owned match table, its use by
the platform driver, and the missing module alias publication.

The AD3532R/AD3532 is a 16-channel, 16-bit voltage output DAC. It shares
similar functionality with AD3530R but splits its registers into two
banks: bank 0 at 0x10xx for channels 0-7 and bank 1 at 0x30xx for
channels 8-15. The input, LDAC trigger and operating-mode registers are
therefore selected per bank.
Add the AD3532R register map, channel specs, per-bank register arrays, a
dedicated powerdown handler and its own regmap_config, reusing the
table-driven helpers for the shared configuration steps.

Devices with a multi-bank register map repeat the same configuration
across several banks, which the hardcoded register addresses in
ad3530r_setup() cannot cover.
Move the addresses into per-chip arrays and add ad3530r_set_reg_bank_bits()

- Only defer IOMMU configuration during initialization. This avoids
an issue where IOMMU configuration could be indefinitely deferred
- Add the missing build salt to the vDSO
- Now that RISC-V systems with higher numbers of cores are starting to
become available, raise NR_CPUS for RISC-V to 256
- Clean up some warnings from sparse caused by the RISC-V-optimized
RAID6 code
- Clean up our __cpu_up() code with a few minor fixes

Pull RISC-V fixes from Paul Walmsley:
- Fix a crash when a kretprobe reads from the stack
- Fix an issue with the build-time mcount sorter that broke ftrace
- Fix the rv32 IRQ stack frame padding to match the ABI
- Only defer IOMMU configuration during initialization. This avoids an
issue where IOMMU configuration could be indefinitely deferred
- Add the missing build salt to the vDSO
- Now that RISC-V systems with higher numbers of cores are starting to
become available, raise NR_CPUS for RISC-V to 256
- Clean up some warnings from sparse caused by the RISC-V-optimized
RAID6 code
- Clean up our __cpu_up() code with a few minor fixes
