978134c4b1 Input: fix open count when closing inhibited device
Because the kernel increments device's open count in input_open_device()
even if device is inhibited, the counter should always be decremented in
input_close_device() to keep it balanced.

3516fa162a Input: avoid calling input_set_abs_val() in the event handling core
input_abs_set_val() can nominally call input_alloc_absinfo() which may
allocate memory with GFP_KERNEL flag. This does not happen when
input_abs_set_val() is called by the input core to set current MT slot when
handling a new input event, but it trips certain static analyzers.

Rearrange the code to access the relevant structures directly.

e0f41f836f Input: tests - modular KUnit tests should not depend on KUNIT=y
While KUnit tests that cannot be built as a loadable module must depend
on "KUNIT=y", this is not true for modular tests, where it adds an
unnecessary limitation.

Fix this by relaxing the dependency to "KUNIT".

As per the comments for input_allocate_device() and
input_register_device(), input_free_device() must be called only to free
devices that have not been registered.  input_unregister_device()
already calls input_put_device(), thus leading to a use-after-free.

Moreover, the kunit_suite.exit() method is called after every test case,
even on failures.  As the test itself already does cleanups in its
failure paths, this may lead to a second use-after-free.

Fix the first issue by dropping the call to input_allocate_device() from
input_test_exit().
Fix the second issue by making the cleanup code conditional on a
successful test.

3a2df60200 Input: uinput - allow injecting event times
Currently, uinput doesn't use the input_set_timestamp API, so any
event injected using uinput is not accurately timestamped in terms of
measuring when the actual event happened. Hence, call the
input_set_timestamp API from uinput in order to provide a more
accurate sense of time for the event. Propagate only the timestamps
which are a) positive, b) within a pre-defined offset (10 secs) from
the current time, and c) not in the future.

dbe836576f Input: cyttsp4_core - change del_timer_sync() to timer_shutdown_sync()
The watchdog_timer can schedule tx_timeout_task and watchdog_work
can also arm watchdog_timer. The process is shown below:

----------- timer schedules work ------------
cyttsp4_watchdog_timer() //timer handler
  schedule_work(&cd->watchdog_work)

----------- work arms timer ------------
cyttsp4_watchdog_work() //workqueue callback function
  cyttsp4_start_wd_timer()
    mod_timer(&cd->watchdog_timer, ...)

Although del_timer_sync() and cancel_work_sync() are called in
cyttsp4_remove(), the timer and workqueue could still be rearmed.
As a result, the possible use after free bugs could happen. The
process is shown below:

  (cleanup routine)           |  (timer and workqueue routine)
cyttsp4_remove()              | cyttsp4_watchdog_timer() //timer
  cyttsp4_stop_wd_timer()     |   schedule_work()
    del_timer_sync()          |
                              | cyttsp4_watchdog_work() //worker
                              |   cyttsp4_start_wd_timer()
                              |     mod_timer()
    cancel_work_sync()        |
                              | cyttsp4_watchdog_timer() //timer
                              |   schedule_work()
    del_timer_sync()          |
  kfree(cd) //FREE            |
                              | cyttsp4_watchdog_work() // reschedule!
                              |   cd-> //USE

This patch changes del_timer_sync() to timer_shutdown_sync(),
which could prevent rearming of the timer from the workqueue.

d09dbc7a01 Input: drv260x - fix magnitude handling
First of all, previously the 16-bit magnitude was written as-is to the
device which actually discarded the upper 8 bits since the device has
8-bit registers only. This meant that a strong_magnitude of 0xFF00 would
result in 0. To correct this shift the strong_magnitude / weak_magnitude
input values so we discard the lower 8 bits and keep the upper bits
instead.

Secondly the RTP mode that is used by default interprets the values as
signed (2s complement), so 0x81 = 0%, 0x00 = 50%, 0x7F = 100%. This
doesn't match the FF_RUMBLE interface at all, so let's tell the device
to interpret the data as unsigned instead which gets us 0x00 = 0% and
0xFF = 100%.

As last change switch ERM to using "Closed-Loop Mode, Unidirectional"
instead of "Open-Loop Mode" since it's recommended by the datasheet
compared to open loop and better matches our use case of 0% - 100%
vibration.

pen down happened, should always be triggered. This enables the usage of

fdefcbdd6f Input: Add KUnit tests for some of the input core helper functions
The input subsystem doesn't currently have any unit tests, let's add a
CONFIG_INPUT_KUNIT_TEST option that builds a test suite to be executed
with the KUnit test infrastructure.

For now, only three tests were added for some of the input core helper
functions that are trivial to test:

  * input_test_polling: set/get poll interval and set-up a poll handler.

  * input_test_timestamp: set/get input event timestamps.

  * input_test_match_device_id: match a device by bus, vendor, product,
                                version and events capable of handling.

But having the minimal KUnit support allows to add more tests and suites
as follow-up changes. The tests can be run with the following command:

  $ ./tools/testing/kunit/kunit.py run --kunitconfig=drivers/input/tests/

57d94d150d Input: add a new Novatek NVT-ts driver
Add a new driver for the Novatek i2c touchscreen controller as found
on the Acer Iconia One 7 B1-750 tablet. Unfortunately the touchscreen
controller model-number is unknown. Even with the tablet opened up it
is impossible to read the model-number.

Android calls this a "NVT-ts" touchscreen, but that may apply to other
Novatek controller models too.

This appears to be the same controller as the one supported by
https://github.com/advx9600/android/blob/master/touchscreen/NVTtouch_Android4.0/NVTtouch.c
but unfortunately that does not give us a model-number either.

db7220c48d Input: xpad - fix support for some third-party controllers
Some third-party controllers, such as the HORPIAD FPS for Nintendo Switch and
Gamesir-G3w, require a specific packet that the first-party XInput driver sends
before it will start sending reports. It's not currently known what this packet
does, but since the first-party driver always sends it's unlikely that this
could cause issues with existing controllers.

cbedf1a339 Input: i8042 - add TUXEDO devices to i8042 quirk tables for partial fix
A lot of modern Clevo barebones have touchpad and/or keyboard issues after
suspend fixable with nomux + reset + noloop + nopnp. Luckily, none of them
have an external PS/2 port so this can safely be set for all of them.

I'm not entirely sure if every device listed really needs all four quirks,
but after testing and production use, no negative effects could be
observed when setting all four.

Setting SERIO_QUIRK_NOMUX or SERIO_QUIRK_RESET_ALWAYS on the Clevo N150CU
and the Clevo NHxxRZQ makes the keyboard very laggy for ~5 seconds after
boot and sometimes also after resume. However both are required for the
keyboard to not fail completely sometimes after boot or resume.

754ff5060d Input: alps - fix compatibility with -funsigned-char
The AlpsPS/2 code previously relied on the assumption that `char` is a
signed type, which was true on x86 platforms (the only place where this
driver is used) before kernel 6.2. However, on 6.2 and later, this
assumption is broken due to the introduction of -funsigned-char as a new
global compiler flag.

Fix this by explicitly specifying the signedness of `char` when sign
extending the values received from the device.

If a platform driver's remove callback returns non-zero the driver core
emits an error message. In such a case however iqs62x_keys_remove()
already issued a (better) message. So return zero to suppress the
generic message.

This patch has no other side effects as platform_remove() ignores the
return value of .remove() after the warning.

007e50eb5d Input: hideep - optionally reset controller work mode to native HiDeep protocol
The HiDeep IST940E touchscreen controller used on the Lenovo Yoga Book X90F
convertible comes up in HID mode by default.

This works well on the X91F Windows model where the touchscreen is
correctly described in ACPI and ACPI takes care of controlling
the reset GPIO and regulators.

But the X90F ships with Android and the ACPI tables on this model don't
describe the touchscreen. Instead this is hardcoded in the vendor kernel.

The vendor kernel uses the touchscreen in native HiDeep 20 (2.0?) protocol
mode and switches the controller to this mode by writing 0 to reg 0x081e.

Adjusting the i2c-hid code to deal with the reset-gpio and regulators on
this non devicetree (but rather broken ACPI) convertible is somewhat tricky
and the native protocol reports ABS_MT_PRESSURE and ABS_MT_TOUCH_MAJOR
which are not reported in HID mode, so it is preferable to use the native
mode.

Add support to the hideep driver to reset the work-mode to the native
HiDeep protocol to allow using it on the Lenovo Yoga Book X90F.
This is guarded behind a new "hideep,force-native-protocol" boolean
property, to avoid changing behavior on other devices.

For the record: I did test using the i2c-hid driver with some quick hacks
and it does work. The I2C-HID descriptor is available from address 0x0020,
just like on the X91F Windows model.

So far the new "hideep,force-native-protocol" property is only used on
x86/ACPI (non devicetree) devs. IOW it is not used in actual devicetree
files. The devicetree-bindings maintainers have requested properties like
these to not be added to the devicetree-bindings, so the new property is
deliberately not added to the existing devicetree-bindings.

When the quirk for the X91F/L was initially added it was written to
also apply to the X90F/L but this does not work because the Android
version of the Yoga Book uses completely different DMI strings.
Also adjust the X91F/L quirk to reflect that it only applies to

3d4e1bad78 thermal/core: Use the thermal zone 'devdata' accessor in remaining drivers
The thermal zone device structure is exposed to the different drivers
and obviously they access the internals while that should be
restricted to the core thermal code.

In order to self-encapsulate the thermal core code, we need to prevent
the drivers accessing directly the thermal zone structure and provide
accessor functions to deal with.

Use the devdata accessor introduced in the previous patch.

11c7052998 ARM: SoC drivers for 6.3
As usual, there are lots of minor driver changes across SoC platforms
 from  NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
 These usually add support for additional chip variations in existing
 drivers, but also add features or bugfixes.
 
 The SCMI firmware subsystem gains a unified raw userspace interface
 through debugfs, which can be used for validation purposes.
 
 Newly added drivers include:
 
  - New power management drivers for StarFive JH7110, Allwinner D1 and
    Renesas RZ/V2M
 
  - A driver for Qualcomm battery and power supply status
 
  - A SoC device driver for identifying Nuvoton WPCM450 chips
 
  - A regulator coupler driver for Mediatek MT81xxv

Merge tag 'soc-drivers-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC driver updates from Arnd Bergmann:
 "As usual, there are lots of minor driver changes across SoC platforms
  from NXP, Amlogic, AMD Zynq, Mediatek, Qualcomm, Apple and Samsung.
  These usually add support for additional chip variations in existing
  drivers, but also add features or bugfixes.

  The SCMI firmware subsystem gains a unified raw userspace interface
  through debugfs, which can be used for validation purposes.

  Newly added drivers include:

   - New power management drivers for StarFive JH7110, Allwinner D1 and
     Renesas RZ/V2M

   - A driver for Qualcomm battery and power supply status

   - A SoC device driver for identifying Nuvoton WPCM450 chips

a93e884edf Driver core changes for 6.3-rc1
Here is the large set of driver core changes for 6.3-rc1.
 
 There's a lot of changes this development cycle, most of the work falls
 into two different categories:
   - fw_devlink fixes and updates.  This has gone through numerous review
     cycles and lots of review and testing by lots of different devices.
     Hopefully all should be good now, and Saravana will be keeping a
     watch for any potential regression on odd embedded systems.
   - driver core changes to work to make struct bus_type able to be moved
     into read-only memory (i.e. const)  The recent work with Rust has
     pointed out a number of areas in the driver core where we are
     passing around and working with structures that really do not have
     to be dynamic at all, and they should be able to be read-only making
     things safer overall.  This is the contuation of that work (started
     last release with kobject changes) in moving struct bus_type to be
     constant.  We didn't quite make it for this release, but the
     remaining patches will be finished up for the release after this
     one, but the groundwork has been laid for this effort.
 
 Other than that we have in here:
   - debugfs memory leak fixes in some subsystems
   - error path cleanups and fixes for some never-able-to-be-hit
     codepaths.
   - cacheinfo rework and fixes
   - Other tiny fixes, full details are in the shortlog
 
 All of these have been in linux-next for a while with no reported
 problems.

ff0c7e1862 ARM: unused boardfile removal for 6.3
This is a follow-up to the deprecation of most of the old-style board
 files that was merged in linux-6.0, removing them for good.
 
 This branch is almost exclusively dead code removal based on those
 annotations. Some device driver removals went through separate subsystem
 trees, but the majority is in the same branch, in order to better handle
 dependencies between the patches and avoid breaking bisection.
 
 Unfortunately that leads to merge conflicts against other changes in the
 subsystem trees, but they should all be trivial to resolve by removing
 the files.
 
 See commit 7d0d3fa733 ("Merge tag 'arm-boardfiles-6.0' of
 git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc") for the
 description of which machines were marked unused and are now removed. The
 only removals that got postponed are Terastation WXL (mv78xx0) and
 Jornada720 (StrongARM1100), which turned out to still have potential
 users.

Jeff LaBundy
4d3d2694e1 Input: iqs626a - drop unused device node references
Each call to device/fwnode_get_named_child_node() must be matched
with a call to fwnode_handle_put() once the corresponding node is
no longer in use. This ensures a reference count remains balanced
in the case of dynamic device tree support.

Currently, the driver never calls fwnode_handle_put(); this patch
adds the missing calls. Because fwnode_handle_put() does not take
a const *fwnode_handle, the const qualifier is removed across all
corresponding *fwnode_handle instances.

As part of this change, trackpad channel touch thresholds and ATI
base values are now specified under single trackpad channel child
nodes. This enhancement moves both properties to scalar values as
opposed to arrays, making their types consistent across bindings.

Richard Kjerstadius
0424931431 Input: cyttsp5 - fix bitmask for touch buttons
Prior to this patch, the bitmask ends up being 0x3, as opposed to 0x1
which likely was the intention. The erroneous bit results in the driver
reporting 2 different button activations in designs with 2 or more
buttons.

To detect which button has been pressed, cyttsp5_btn_attention() uses a
for loop to iterate through the input buffer, while shifting and
applying a bitmask to determine the state for each button.
Unfortunately, when the bitmask is 0x3 and there are multiple buttons,
this procedure falls apart.

Consider a design with 3 buttons. Pressing the third button will result
in a call to cyttsp5_btn_attention() with the input buffer containing
0x4 (binary 0100). In the first iteration of the for loop cur_btn_state
will be:

(0x4 >> 0 * 1) & 0x3 = 0x4 & 0x3 = 0x0

This is correct. However, in the next iteration this happens:

(0x4 >> 1 * 1) & 0x3 = 0x2 & 0x3 = 0x2

Which means that a key event for key 1 is generated, even though it's
not really active. In the third iteration, the loop detects the button
that was actually pressed:

(0x4 >> 2 * 1) & 0x3 = 0x1 & 0x3 = 0x1

This key event is the only one that should have been detected, but it is
accompanied by the preceding key. Ensuring the applied mask is 0x1
solves this problem.

2e99b1b065 mfd: remove ucb1400 support
The ucb1400 MFD driver and its gpio and touchscreen child
drivers were only used on a few PXA machines that were unused
for a while and are now removed.

Removing these leaves the AC97 support as ALSA specific,
no other drivers are now connected through this interface.

13f82ca387 Input: ads7846 - always set last command to PWRDOWN
Controllers that report pressure (e.g. ADS7846) use 5 commands and the
correct sequence is READ_X, READ_Y, READ_Z1, READ_Z2, PWRDOWN.

Controllers that don't report pressure (e.g. ADS7845/ADS7843) use only 3
commands and the correct sequence should be READ_X, READ_Y, PWRDOWN. But
the sequence sent was incorrect: READ_X, READ_Y, READ_Z1.

Fix this by setting the third (and last) command to PWRDOWN.

47e79d3109 Input: wistron_btns - use pm_sleep_ptr() to allow removal of ifdef CONFIG_PM guards
As the guards only apply to suspend and resume, #ifdef CONFIG_PM_SLEEP
would have been a tighter protection. As pm_sleep_ptr() lets the compiler
see the protected ops structure and callbacks but also lets the compiler
remove it as unused code if !CONFIG_PM_SLEEP this allows the #ifdef
guards to be removed, slightly simplifying the resulting code.

--
It seems likely that DEFINE_SIMPLE_DEV_PM_OPS() would work here but
I'd prefer not to make that change unless someone can confirm that the
extra callbacks registered will have no unwanted side effects in this
driver.
