In mms114_suspend, the driver synthesizes touch release events for all
slots and calls input_sync before disabling the hardware interrupt via
mms114_stop. Because the threaded interrupt handler runs independently
and does not share a lock with this early part of the suspend path, an
incoming hardware interrupt can fire after input_sync completes but
before disable_irq is invoked.
If a touch event arrives during this window, the interrupt handler
reports the touch slot as active again, overwriting the synthetic
release event right before the system goes to sleep. Upon resume,
lifting the finger does not generate a release interrupt, potentially
leaving userspace with a stuck active touch slot.
Fix this race by calling mms114_stop, which disables the IRQ and
synchronizes with any executing interrupt handler, before synthesizing
the touch release events. Also ensure that we only synthesize touch
release events if the input device is enabled, keeping the entire
suspend sequence protected by input_dev->mutex.

The use of SIMPLE_DEV_PM_OPS got deprecated in commit
1a3c7bb08826 ("PM: core: Add new *_PM_OPS macros, deprecate old ones")
So convert the pm ops to use its replacement: DEFINE_SIMPLE_DEV_PM_OPS.
This also allows us to drop the __maybe_unused attributes.

System suspend powers the controller off and resume powers it back on,
but the resume path enables the interrupt before s6sy761_power_on()
checks the boot. The firmware raises its boot-complete event on the
interrupt line, the threaded handler consumes it, s6sy761_power_on()
then reads an empty event and resume fails with -ENODEV, skipping the
touch function setup:
s6sy761 2-0048: PM: dpm_run_callback(): s6sy761_resume [s6sy761] returns -19
Power the chip on first and only then unmask the interrupt. Once resume
completes the boot handshake the chip comes back with sensing off, as
at probe where input_open() turns it on, so the touchscreen stays dead
after resume. Send SENSE_ON again when the input device is open.
Tested on a Pixel 3 XL over several s2idle cycles: resume succeeds and
the touch function and sense status match the pre-suspend state.

The "ti,poll-period" property is documented as a normal uint32 cell.
The driver used a u64 helper, which makes the helper type disagree with
the schema even though the stored value is still small.
Read "ti,poll-period" with the u32 helper matching the documented DT
cell size.

Nothing in suspend.h needs swap.h. However, many files indirectly
depend on some of swap.h's dependencies, so this is a large
cross-subsystem patch. Stats:
42 are missing includes of interrupt.h (the question of why swap.h
brings in interrupt.h remains unanswered).
10 missing includes of seq_file.h
5 missing includes of swap.h (obviously all files could have just added
swap.h, but I preferred to bring in a more minimal inclusion set)
3 missing includes of highmem.h
2 missing includes of device.h
2 missing includes of string_choices.h
1 missing include of cacheflush.h
1 missing include of dma-direction.h
1 missing include of kthread.h
1 missing include of pagemap.h
1 missing include of string_helpers.h
1 missing include of writeback.h
I tried to follow whatever conventions appeared to be in use for the
various subsystems I touched; for example I added string_choices.h to
drm_print.h instead of individually to each driver which used the
functions declared there.

request are:
- Loads of IIO driver updates and additions
- binder driver updates (more on that below...)
- Removal of the SGI XP and GRU drivers as they are not used anymore
and turn out to be pretty insecure overall
- Removal of the obsolete ibmasm driver as it's not being used
anymore
- Coresight driver updates and additions

- Counter driver updates
- FPGA driver updates
- ICC driver updates
- lots and lots of other tiny driver updates to resolve reported

26.5 GHz.
- Included infrastructure to handle higher precision attributes with
extensive tests
adi,ltc2378-20

st,vl53l1x
- Refactors to improve readability.
ti,ads112c14
- New driver supporting the ADS112C14 and ADS122C14 ADCs. These bring
some new ABI for input chopping, particular useful for resistive sensors
like thermocouples or Wheatstone bridges.

specification of currents used for resistive sensor measurement.
- reference-sources property to allow selection of a per channel reference.
rockchip,saradc
- Add RV1106 which is compatible with the RV3588.
Features
--------
buffer-dmaengine

Cleanups, minor fixes
---------------------
Minor cleanups not mentioned at all in this summary such
as white space fixes or typos.
Affecting various drivers
- Cleanup of conditionals that had no affect.
- Drop some runtime pm local wrappers as now runtime_pm does the
mark_last_busy part inside the put, these provide no useful code
deduplication or readability advantages over directly calling the
runtime_pm functions.
- Return 0 from write_raw() on success.
- Use of dev_err_probe() to simplify code and sometimes provide useful
info for deferred probe debugging.
- Drop some redundant error prints where the called function already
provides information on errors.
- Make some read only arrays in functions static.
- Fix up missing handling of regcache_sync() errors.
- Drop some false kernel-doc markings.
- Add missing MODULE_DEVICE_TABLE for some of_match_id tables.
- Use local variables for things like the struct device to shorten and
improve readability of code.
- Drop some unused structure elements.
- Reorder dds.h macro parameters to be inline with others.
- Header reorders and IWYU. Often part of a more significant series.
- Remove abstractions designed to allow a driver to support multiple device
types, when they have been around a long time and only the original part
showed up.
- Initialize spi_device_id arrays using member names following dropping of
driver data from drivers that didn't actually use it.
- Catch up with i2c_device_id tables added since previous effort to use
named initializers for all those.
- Use kernel types in a few places instead of standard C ones or bare
unsigned.
Misc
- Update Xilinx AMS maintainer.
- Update email address for Maxwell Doose.
- Update email address for Siratul Islam.
- Update email address for Tomasz Duszynski and re-add Tomasz to
various maintainer entries.
Docs

flexibility in input to differential pair mapping. Intended to
provide a strong signal to userspace that a channel is differential.
adi,ad_sigma_delta
- Allow COMPILE_TEST without any users.
adi,ad2s1201
- Refactor trigger handler to avoid mix of guard() and goto.
adi,ad5686

- Ensure runtime_pm is balanced on error in probe.
rohm,bm1390
- Make the driver slightly more likely to recover from transient errors.
sensiron,sgp30
- Handle thread creation errors.
st,lsm6dsx
- Update the enable mask when doing sensor fusion to avoid incorrect fifo
data handling.
st,stm32-dfsdm
- Treat dt flags as booleans.
ti,ads1015
- Switch to devm helpers which simplified code and closed a resource leak.
ti,opt3001
- Split complicated opt3001_get_processed() logic into irq an no irq
helper functions.
- Use devm to simplify code.
- Use guard() to simplify code.
- Reorder probe so final call exposes userspace interfaces.

In sur40_probe(), if video_register_device() fails, the error path jumps to
err_unreg_video. This incorrectly attempts to unregister a video device
that was never successfully registered, and fails to free the V4L2 control
handler (v4l2_ctrl_handler_free) that was initialized immediately prior.
Fix this by introducing an err_free_ctrl label to properly free the V4L2
control handler and bypass video_unregister_device() when video device
registration fails.

In sur40_probe(), input_register_device() was previously called early before
the V4L2 video device and vb2_queue components were fully initialized. If
userspace opened the input device immediately upon registration, sur40_open()
would trigger and start the sur40_poll() worker thread. This worker thread
invokes sur40_process_video() and accesses the uninitialized vb2_queue
structure, leading to a data race and potential system crash.
Furthermore, if V4L2 or video registration failed after input_register_device()
succeeded, the error path fell through to calling input_free_device() on a
successfully registered device instead of input_unregister_device(), corrupting
input core state.
Move input_register_device() to the very end of sur40_probe(). This ensures
the V4L2 and video queue structures are fully initialized before polling can
start, and naturally resolves the error path bug since input_free_device()
is now only called when input registration has not yet occurred.
To maintain strict LIFO (Last-In, First-Out) teardown ordering, also move
input_unregister_device() to the very beginning of sur40_disconnect(). This
guarantees that the input polling worker thread is stopped before V4L2
video components or control handlers are unregistered.

The driver allocates max_touch_num input slots, which are indexed from
zero through max_touch_num - 1. The current check allows a finger ID
equal to max_touch_num to reach cst3xx_report_contact(). While the input
core ignores out-of-range slot indices, reporting touch data without a
valid slot change corrupts the touch state of the previously active slot.
The touch count is read from the controller's report and is used to
index the fixed-size report buffer without first checking its range.
Reject counts larger than the supported number of touch slots before
checking the trailing byte or parsing touch data.
Reject finger IDs equal to or greater than max_touch_num, and return
immediately when an invalid finger ID is encountered so that corrupt
touch frames are discarded instead of reporting partial contact state.
The V821 Avaota F1 board configures the vendor driver with one touch
slot, so finger ID 1 is already invalid on that device.

The firmware record parser checks that the record address starts within
the programmable map, but does not check that the complete record data
fits in that map. A record near the end of the map can therefore make
the copy to pmap exceed its destination span.
Check the record length against the remaining programmable map range
before copying the record data.

The per-contact slot id is taken from the top nibble of the third
report byte, so it can be any value from 0 to 15. The driver only
allocates max_support_points MT slots (2 to 10 depending on the
variant), so a report that carries an id at or above that count - be it
a genuinely higher-numbered contact or a corrupted byte - is outside the
range the input core was told about.
input_mt_slot() silently ignores an ABS_MT_SLOT beyond num_slots and
leaves the current slot unchanged, so the following
input_mt_report_slot_state()/touchscreen_report_pos() pair is applied to
whichever slot happened to be selected last, reporting the contact at the
wrong position. Skip such entries instead.

In preparation for removing the strlcat() API[1], replace its five
uses with a small append helper built on strnlen() and strscpy().
The five calls append device name fragments to a basename buffer
that grows in place across the setup functions. The helper takes
the same arguments as strlcat() and writes the same bytes, including
when a fragment is truncated.

The driver defines the I2C packet layout using C bitfields in struct
mms114_touch. This is not portable as the layout of bitfields within a
byte is compiler-dependent and varies with endianness. On Big Endian
systems, the fields will be parsed incorrectly.
Fix this by redefining struct mms114_touch with plain u8 fields and
introducing bitwise macros to extract the values portably.

If the touchscreen controller reports a touch ID of 0, the driver
calculates the slot ID as touch->id - 1, which underflows to UINT_MAX.
This is passed to input_mt_slot() as -1.
Since the input core ignores negative slot values, the active slot remains
unchanged. The driver then reports the touch coordinates for the previously
active slot, corrupting its state.
Fix this by rejecting touch reports with ID 0.

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.

Instead of using an enum and conditional switch/if statements throughout
the driver to handle differences between chip variants (MMS114, MMS134S,
MMS136, MMS152, MMS345L), introduce a variant-specific descriptor
structure that encapsulates variant-specific properties (name, event
size, presence of configuration registers) and callbacks (such as
get_version). Define descriptors for each supported chip and associate
them with the matching entries in the OF and I2C device ID tables.
This eliminates the need for variant checks in the driver logic, making
it easier to support new chip variants in the future.
Note that there is slight change in device names:
MMS134S: "MELFAS MMS134 Touchscreen" -> "MELFAS MMS134S Touchscreen"
MMS345L: "MELFAS MMS345 Touchscreen" -> "MELFAS MMS345L Touchscreen"

Avoid taking the machine down with BUG() if a caller ever requests a
