cdd30ebb1b module: Convert symbol namespace to string literal
Clean up the existing export namespace code along the same lines of
commit 33def8498f ("treewide: Convert macro and uses of __section(foo)
to __section("foo")") and for the same reason, it is not desired for the
namespace argument to be a macro expansion itself.

b4b42f28a0 iio: fix write_event_config signature
write_event_config callback use an int for state, but it is actually a
boolean. iio_ev_state_store is actually using kstrtobool to check user
input, then gives the converted boolean value to write_event_config.

Fix signature and update all iio drivers to use the new signature.

This patch has been partially written using coccinelle with the
following script:

$ cat iio-bool.cocci
// Options: --all-includes

virtual patch

@c1@
identifier iioinfo;
identifier wecfunc;
@@
 static const struct iio_info iioinfo = {
        ...,
        .write_event_config =
(
 wecfunc
|
 &wecfunc
),
        ...,
 };

@@
identifier c1.wecfunc;
identifier indio_dev, chan, type, dir, state;
@@
 int wecfunc(struct iio_dev *indio_dev, const struct iio_chan_spec *chan, enum iio_event_type type, enum iio_event_direction dir,
-int
+bool
 state) {
  ...
 }

make coccicheck MODE=patch COCCI=iio-bool.cocci M=drivers/iio

Unfortunately, this script didn't match all files:
* all write_event_config callbacks using iio_device_claim_direct_scoped
  were not detected and not patched.
* all files that do not assign and declare the write_event_config
  callback in the same file.

iio.h was also manually updated.

The patch was build tested using allmodconfig config.

6a9262edff iio: Switch back to struct platform_driver::remove()
After commit 0edb555a65 ("platform: Make platform_driver::remove()
return void") .remove() is (again) the right callback to implement for
platform drivers.

Convert all platform drivers below drivers/iio/ to use .remove(), with
the eventual goal to drop struct platform_driver::remove_new(). As
.remove() and .remove_new() have the same prototypes, conversion is done
by just changing the structure member name in the driver initializer.

While touching these files, make indention of the struct initializer
consistent in several files.

4391affa10 iio: Drop explicit initialization of struct i2c_device_id::driver_data to 0
These drivers don'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.

While add it, also remove commas after the sentinel entries.

f7b6443f34 iio: sx9324: avoid copying property strings
We're doing some needless string copies when trying to assign the proper
`prop` string. We can make `prop` a const char* and simply assign to
string literals.

For the case where a format string is used, let's extract the parsing
logic out into sx9324_parse_phase_prop(). We no longer need to create
copies or allocate new memory.

sx9324_parse_phase_prop() will simply return the default def value if it
fails.

This also cleans up some deprecated strncpy() uses [1].

Furthermore, let's clean up this code further by removing some unused
defines:
|  #define SX9324_PIN_DEF "semtech,ph0-pin"
|  #define SX9324_RESOLUTION_DEF "semtech,ph01-resolution"
|  #define SX9324_PROXRAW_DEF "semtech,ph01-proxraw-strength"

b4b6cc10c6 IIO: 1st set of new device support, features and cleanup for 6.7
Particularly great to see a resolver driver move out of staging via a
 massive set of changes.  Only took 13 years :)
 
 One small patch added then reverted due to a report of test breakage
 (ashai-kasei,ak8975: Drop deprecated enums.)
 
 An immutable branch was used for some hid-senors changes in case
 there was a need to take them into the HID tree as well.
 
 New device support
 -----------------
 
 adi,hmc425a
   - Add support for HMC540SLP3E broadband 4-bit digital attenuator.
 kionix,kx022a
   - Add support for the kx132-1211 accelerometer. Require significant
     driver rework to enable this including add a chip type specific
     structure to deal with the chip differences.
   - Add support for the kx132acr-lbz accelerometer (subset of the kx022a
     feature set).
 lltc,ltc2309
   - New driver for this 8 channel ADC.
 microchip,mcp3911
   - Add support for rest of mcp391x family of ADCs (there are various
     differences beyond simple channel count variation.
     Series includes some general driver cleanup.
 microchip,mcp3564
   - New driver for MCP3461, MCP3462, MCP3464, MCP3541, MCP3562, MCP3564
     and their R variants of 16/24bit ADCs. A few minor fixed followed.
 rohm,bu1390
   - New driver for this pressure sensor.
 
 Staging graduation
 ------------------
 
 adi,ad1210 (after 13 or so years :)
   - More or less a complete (step-wise) rewrite of this resolver driver
     to bring it up to date with modern IIO standards.  The fault signal
     handling mapping to event channels was particularly complex and
     significant part of the changes.

 --------
 
 iio-core
  - Add chromacity and color temperature channel types.
 adi,ad7192
   - Oversampling ratio control (called fast settling in datasheet).

   - Add core support and then driver support for delta angle and delta
     velocity channels. These are intended for summation to establish
     angle and velocity changes over larger timescales.  Fix was
     needed for alignment after the temperature channel.  Further fix
     reduced set of devices for which the buffer support was applicable
     as seems burst reads don't cover these on all devices.

   - Chromacity and color temperatures support including in amd sfh.

     entry.
   - Use device_get_match_data() for various platform device to cope
     with more types of firmware.

The problem seems to be that irsd200_trigger_handler() is taking a s16
variable as an int64_t buffer. As Jonathan suggested [1], fix it by
extending the buffer to a two-element array of s64.

4abfc97db9 iio: proximity: srf04: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

2df694f710 iio: proximity: cros_ec_mkbp: Convert to platform remove callback returning void
The .remove() callback for a platform driver returns an int which makes
many driver authors wrongly assume it's possible to do error handling by
returning an error code. However the value returned is ignored (apart
from emitting a warning) and this typically results in resource leaks.
To improve here there is a quest to make the remove callback return
void. In the first step of this quest all drivers are converted to
.remove_new() which already returns void. Eventually after all drivers
are converted, .remove_new() will be renamed to .remove().

Trivially convert this driver from always returning zero in the remove
callback to the void returning variant.

Convert enum->pointer for data in match data table, so that
device_get_match_data() can do match against OF/ACPI/I2C tables, once i2c
bus type match support added to it.

Add struct sx931x_info and replace enum->sx931x_info in the match table
and simplify sx9310_check_whoami().

1240c94ce8 iio: adc: Explicitly include correct DT includes
The DT of_device.h and of_platform.h date back to the separate
of_platform_bus_type before it as merged into the regular platform bus.
As part of that merge prepping Arm DT support 13 years ago, they
"temporarily" include each other. They also include platform_device.h
and of.h. As a result, there's a pretty much random mix of those include
files used throughout the tree. In order to detangle these headers and
replace the implicit includes with struct declarations, users need to
explicitly include the correct includes.

e522a6f7cb iio: proximity: sx_common: Add old register mapping
Older firmwares still send sensor configuration using a list of
registers with opaque values defined during sensor tuning.
sx9234 and sx9360 sensor on ACPI based devices are concerned.
More schema to configure the sensors will be needed to support devices
designed for windows, like Samsung Galaxy Book2.

Support schema is: "<_HID>.<register_name>". For instance
"STH9324,reg_adv_ctrl2" in:

    Scope (\_SB.PCI0.I2C2)
    {
        Device (SX28)
        {
            Name (_HID, "STH9324")  // _HID: Hardware ID
...
            Name (_DSD, Package (0x02)  // _DSD: Device-Specific Data
            {
                ToUUID ("daffd814-6eba-4d8c-8a91-bc9bbf4aa301") /*
Device Properties for _DSD */,
                Package (0x3F)
                {
...
                    Package (0x02)
                    {
