Pull char/misc and other driver subsystem updates from Greg KH:
"Here is the big set of char/misc and a number of other driver
subsystem updates for 6.9-rc1. Included in here are:
- IIO driver updates, loads of new ones and evolution of existing ones
- coresight driver updates
- const cleanups for many driver subsystems
- speakup driver additions
- platform remove callback void cleanups
- mei driver updates
- mhi driver updates
- cdx driver updates for MSI interrupt handling
- nvmem driver updates
- other smaller driver updates and cleanups, full details in the
shortlog
All of these have been in linux-next for a long time with no reported
issue, other than a build warning for the speakup driver"
The build warning hits clang and is a gcc (and C23) extension, and is
fixed up in the merge.

There's no reason to have a nested if/then schema as checking for compatible

The servers for the @codeaurora domain have long been retired and any
messages sent there will bounce. Fix Odelu's address in the binding to
match the .mailmap entry so that folks see the correct address when
looking at the documentation.

signal which can be used for signaling to the host.
Add binding for "interrupts" property so that boards wiring this signal
may describe the connection.

Add the binding to specify the vcc supply. We can't make it required
since this would break the backward compatibility.

The unit for TPDM DSB element size is bits. So rename the property:
qcom,dsb-element-size => qcom,dsb-element-bits
This also makes it consistent with the naming for the CMB element
size property.
There is no tpdm node in any DT as of now. Make this change before
any tpdm node is added to DT.

Bit 0 is PATT_TSENAB bit. Set this bit to 1 to request a timestamp
following a CMB interface pattern match. Bit 1 is XTRIG_TSENAB bit.
Set this bit to 1 to request a timestamp following a CMB CTI timestamp
request. Bit 2 is TS_ALL bit. Set this bit to 1 to request timestamp

Timestamps are requested if the monitor’s CMB data set unit input
data matches the value in the Monitor CMB timestamp pattern and mask
registers (M_CMB_TPR and M_CMB_TPMR) when CMB timestamp enabled
via the timestamp insertion enable register bit(CMB_TIER.PATT_TSENAB).
The pattern match trigger output is achieved via setting values into
the CMB trigger pattern and mask registers (CMB_XPR and CMB_XPMR).
After configuring a pattern through these registers, the TPDM subunit
will assert an output trigger every time it receives new input data
that matches the configured pattern value. Values in a given bit
number of the mask register correspond to the same bit number in
the corresponding pattern register.

TPDM CMB subunits support two forms of CMB data set element creation:
continuous and trace-on-change collection mode. Continuous change
creates CMB data set elements on every CMBCLK edge. Trace-on-change
creates CMB data set elements only when a new data set element differs
in value from the previous element in a CMB data set. Set CMB_CR.MODE
to 0 for continuous CMB collection mode. Set CMB_CR.MODE to 1 for
trace-on-change CMB collection mode.

this size before it is enabled. CMB element size currently only
supports 8-bit, 32-bit and 64-bit. Because the existing example

a new example "tpdm@6c29000" to describe the usage of this new
property.

IIO: 1st set of new device support, features and cleanup for 6.9
IIO Backend support
===================
New approach from Nuno Sa to the problem of reuse of drivers with
IIO devices that are actually the combination of a highspeed chip
and an FPGA core handling the data capture and flows. It will hopefully
also apply to some other split designs. The ad9467 and axi-adi drivers
are converted over to this framework.
New device support
==================
adi,admfm2000
- New driver for this dual microwave down converter.
ams,as73211
- Add support for as7331 UV sensor.
richtek,rtq6056
- Add support for related parts RTQ6053 and RTQ6059
st,lsm6dsx
- Add ASM330LHHXG1 accelerometer and gyro support (mainly IDs)
ti,ads1298
- New driver for this medical ADC.
Features
========
tests
- Unit tests for the gain-time-scale helper library.
bosch,bmi088
- I2C support.
bosh,bmi160
- Add 10EC5280 ACPI ID. Used in a number of devices that won't get fixed.
The ID is actually a PCI ID belonging to realtech. No response was received
to earlier attempts to notify them of this.
The manufacturers of some devices have replied to say they will not fix
this incorrect ID. Add the ID and hope it isn't a problem.
bosch,bmi323
- Add BOSC0200 ACPI ID. Note this is a duplicate of one in the bmc150
driver (it appears these parts share a windows driver).
Both drivers perform an ID check that is safe on the other part before
successfully probing.
hid-sensors-als
- Add color temperature and chromaticity support. Note this is a replacement
for the series reverted in 6.8 that correctly handles all the potential
channel combinations.
honeywell,hsc030pa
- Triggered buffer support (after driver cleanup).
honeywell,mprls00025pa
- Improved error handling.
- New DT binding to allow use of part number triplet as provided in data sheet
to specify equivalent of most of the binding more efficiently.
- SPI support.
memsic,mxc4005
- ACPI ID MDA6655 as seen in the Chuwi Minibook X 2023
ti,hdc3020
- Add threshold event support (after some driver cleanup)
veml,vcnl4000
- Switch to high resolution proximity measurement.
Cleanup
=======
Various minor typo fixes and better use of defines etc.
Treewide
- Stop using ACPI_PTR(). The savings in space are small and not worth
the complexity of __maybe_unused of ifdef guards. To avoid use in
new IIO drivers based on copy and paste, clean it out.
- cleanup.h based handling of iio_device_claim_direct_mode()/
iio_device_release_direct_mode() using scope_cond_guard().
In many drivers this is combined with other automated cleanup
to give maximum simplifications.
An initial set of drivers are converted over to this infrastructure.
Tools
- Use rewinddir() instead of seekdir() to return to start of file.
core
- Make iio_bus_type constant.
adi,ad16475
- Use irq_get_trigger_type() instead of opencoding.
adi,ad16480
- Use irq_get_trigger_type() instead of opencoding.
adi,ad-sigma-delta
- Avoid overwriting IRQ flags if provided by firmware.
ams,as73211
- Use IIO_VAL_FRACTIONAL for scales to simplify the code and potentially
improve accuracy.
gts-library
- Use a div64_u64() instead of a loop to do a division.
honeywell,mprls00025pa
- Clean up dt-binding doc.
- Drop defaults when DT binding not providing values. Very unlikely
these were useful given they were wrong for vast majority of supported
devices.
- Whitespace cleanup
miramems,da280
- Use i2c_get_match_data() to replace hand rolled ACPI matching code.
semtech,sx9324
- Avoid unnecessary copying of property strings.
st,lsm6dsx
- Improve docs, particularly wrt to making addition of new device
support less noisy.
st,lsm9ds0
- Use dev_err_probe() in all probe() error handling.
- Improved header includes.
- Tidy up termination of ID tables.
ti,ads1014
- Correct upper bound on PGA (wrong value had no actual impact)
ti,afe4403/4404
- devm_ useage to simplify error handling in probe() and allow() remove to
be dropped.
voltage-divider
- Add dt-binding for io-channel-cells to allow such a device to be both
an IIO consumer and IIO producer at the same time.

Bindings for the TI ADS1298 medical ADC. This device is
typically used for ECG and similar measurements. Supports data
acquisition at configurable scale and sampling frequency.
The device has so many options for connecting stuff, at this
point the bindings aren't nearly complete but partial bindings
are better than no bindings at all.

'adi,adc-dev' is now deprecated and must not be used anymore. Hence,
also remove it from being required.
The reason why it's being deprecated is because the axi-adc CORE is now
an IIO service provider hardware (IIO backends) for consumers to make use
of. Before, the logic with 'adi,adc-dev' was the opposite (it was kind
of consumer referencing other nodes/devices) and that proved to be wrong
and to not scale.
Now, IIO consumers of this hardware are expected to reference it using the
io-backends property. Hence, the new '#io-backend-cells' is being added
so the device is easily identified as a provider.

The ad9467 will make use of the new IIO backend framework which is a
provider - consumer interface where IIO backends provide services to
consumers. As such, and being this device a consumer, add the new
generic io-backend property to the bindings.

Enable the voltage divider to both receive and provide measurement
services by adding #io-channel-cells.
This is especially valuable in scenarios where an ADC has an analog
frontend, like a voltage divider, and obtaining its raw value isn't
interesting. It is desired to get the real voltage before the voltage
divider.

This device has the same properties and I2C addresses as the as73211.
The only difference between them is the photodiodes they use internally,
which in this case is irrelevant for the bindings.
