Add documentation for the driver of ADS7128 and ADS7138 12-bit, 8-channel
analog-to-digital converters. These ADCs have a wide operating range and
a wide feature set. Communication is based on the I2C interface.
ADS7128 differs in the addition of further hardware features, like a
root-mean-square (RMS) and a zero-crossing-detect (ZCD) module.

Add a new compatible and related bindings for the fpga-based
AD485x AXI IP core, a variant of the generic AXI ADC IP.
The AXI AD485x IP is a very similar HDL (fpga) variant of the
generic AXI ADC IP, intended to control ad485x family.
Although this is not preferred, the wildcard naming is used to
match the published firmware under the same name.

Add interrupt-names INT1 and INT2 for the two interrupt lines of the
sensor.
When one of the two interrupt lines is connected, the interrupt as its
interrupt-name, need to be declared in the devicetree. The driver then
configures the sensor to indicate its events on either INT1 or INT2.
If no interrupt is configured, then no interrupt-name should be
configured, and vice versa. In this case the sensor runs in FIFO BYPASS
mode. This allows sensor measurements, but none of the sensor events.

Extend the AD4000 series device tree documentation to also describe
PulSAR devices.
The single-channel series of PulSAR devices is similar to the AD4000 series
except PulSAR devices sample at slower rates and don't have a
configuration register. Because PulSAR devices don't have a configuration
register, they don't support all features of AD4000 devices and thus fewer
interfaces are provided to user space. Also, while AD4000 may have their
SDI pin connected to SPI host MOSI line, PulSAR SDI pin is never connected
to MOSI.
Some devices within the PulSAR series are just faster versions of others.
>From fastest to slowest, AD7980, AD7988-5, AD7686, AD7685, and AD7988-1 are
all 16-bit pseudo-differential pin-for-pin compatible ADCs. Devices that
only vary on the sample rate are documented with a common fallback
compatible.

For the AD7124 chip and some of its cousins the logical irq line (R̅D̅Y̅)
is physically on the same pin as the spi MISO output (DOUT) and so
reading a register might trigger an interrupt. For correct operation
it's critical that the actual state of the pin can be read to judge if
an interrupt event is a real one or just a spurious one triggered by
toggling the line in its MISO mode.
Allow specification of an "rdy-gpios" property that references a GPIO
that can be used for that purpose. While this is typically the same GPIO
also used (implicitly) as interrupt source, it is still supposed that
the interrupt is specified as before and usual.

Document the ADC IP available on the RZ/G3S SoC. The ADC IP on the RZ/G3S
differs slightly from the one found on the RZ/G2L. The identified
differences are as follows:
- different number of channels (one being used for temperature conversion);
consequently, various registers differ; the temperature channel
support was not available for the RZ/G2L variant; the #io-channel-cells
property was added to be able to request the temperature channel from
the thermal driver
- different default sampling periods
- the RZ/G3S variant lacks the ADVIC register.

expect to see way more rust drivers going forward now that these
bindings are present. Next merge window hopefully we will have pci
and platform drivers working, which will fully enable almost all
driver subsystems to start accepting (or at least getting) rust
drivers. This is the end result of a lot of work from a lot of
people, congrats to all of them for getting this far, you've proved
many of us wrong in the best way possible, working code :)

- pwm driver updates
- platform_driver::remove() fixups, loads of them
- counter driver updates
- misc driver updates (keba?)
- binder driver updates and fixes

Note, there is a semi-hairy rust merge conflict when pulling this. The

family, with the following differences:
- pin selectable gain in front of each 4 adc
- internal reference is 3V derived from refin-supply (5V)
- additional supplies
To select the gain a new patternProperties is added to describe each

Document the bindings for the Allegro MicroSystems ALS31300 3-D Linear
Hall Effect Sensor controller by an I2C interface, mainly used in 3D
head-on motion sensing applications.
The device can be configured with different sensitivities in factory,
but the sensitivity value used to calculate value into the Gauss unit
is not available from registers, thus the sensitivity is provided by
the compatible/device-id string which is based on the part number as
described in the datasheet page 2.

Add a new compatible and related bindigns for the fpga-based
"ad3552r" AXI IP core, a variant of the generic AXI DAC IP.
The AXI "ad3552r" IP is a very similar HDL (fpga) variant of the
generic AXI "DAC" IP, intended to control ad3552r and similar chips,
mainly to reach high speed transfer rates using a QSPI DDR
(dobule-data-rate) interface.
The ad3552r device is defined as a child of the AXI DAC, that in
this case is acting as an SPI controller.
Note, #io-backend is present because it is possible (in theory anyway)
to use a separate controller for the control path than that used
for the datapath.

conversion trigger with iio-backend.
The iio-backend's function is to controls the communication, and thus the
interruption pin won't be available anymore.
As a consequence, the conversion pin must be controlled externally since
we will miss information about when every single conversion cycle (i.e
conversion + data transfer) ends, hence a PWM is introduced to trigger
the conversions.

Some ADCs have channels with negative and positive inputs, which can be
used to measure differential voltage levels. These inputs/pins are
dedicated (to the given channel) and cannot be muxed as with other ADCs.
For those types of setups, the 'diff-channels' property can be specified to
be used with the channel number (or reg property) for both negative and
positive inputs/pins.

Here is the "big" set of char/misc and other driver subsystem changes
for 6.12-rc1. Sorry for the delay, conference travel for the past two
weeks has this and my other pull requests showing up real late
in the cycle.
Lots of changes in here, primarily dominated by the usual IIO driver
updates and additions, but there are also small driver subsystem updates
all over the place. Included in here are:
- lots and lots of new IIO drivers and updates to existing ones
- interconnect subsystem updates and new drivers
- nvmem subsystem updates and new drivers
- mhi driver updates
- power supply subsystem updates
- kobj_type const work for many different small subsystems
- comedi driver fix
- coresight subsystem and driver updates
- fpga subsystem improvements
- slimbus fixups
- binder new feature addition for "frozen" notifications
- lots and lots of other small driver updates and cleanups
All of these have been in linux-next for a long time with no reported
problems.

The legacy sd modulator driver registers the sigma delta modulator as
an IIO channel provider. This implementation is not convenient when the
SD modulator has to be cascaded with another IIO device. The scaling
information is distributed across devices, which makes it difficult to
report consistent scaling data on IIO devices.
The solution is to expose these cascaded IIO devices as an aggregate
device, which report global scaling information.
Add IIO backend support to SD modulator to allow scaling information
management.

Change the DFSDM binding to use the new IIO backend framework,
along with the adoption of IIO generic channels.
This binding change allows to add scaling support to the DFSDM.
Keep the legacy binding as deprecated for backward compatibility.
The io-backends property is supported only in generic IIO channel
binding.
- Channel description with the generic binding (Audio and Analog):
Properties superseded by generic properties:
st,adc-channels: becomes "reg" property in channel node
st,adc-channel-names: becomes "label" property in channel node
Properties moved to channel child node:
st,adc-channel-types: becomes st,adc-channel-type
st,adc-channel-clk-src, st,adc-alt-channel
- Analog binding:
DFSDM filter channel is configured as an IIO backend consumer.
Add io-backends property in channel child nodes.
DFSDM is no more configured as a channel consumer from SD modulator.
Use of io-channels in DFSDM node is deprecated.
- Audio binding:
