Input: include export.h in modules using EXPORT_SYMBOL*()

2025-08-21T19:00:59+00:00

A number of modules in the input subsystem use EXPORT_SYMBOL() and
friends without explicitly including the corresponding header
. While the build currently succeeds due to this header
being pulled in transitively, this is not guaranteed to be the case in
the future.

Let's add the explicit include to make the dependencies clear and
prevent future build breakage.

Input: move input_bits_to_string() to input-compat.c

2025-08-21T19:00:58+00:00

The input_bits_to_string() function has special handling for compat
tasks, formatting the output as a sequence of 32-bit hex values. To
better isolate compatibility-related code, move it from
drivers/input/input.c to drivers/input/input-compat.c.

No functional change intended.

Merge tag 'ib-mfd-gpio-input-pwm-v6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/lee/mfd into next

2025-08-04T06:28:48+00:00

Merge an immutable branch between MFD, GPIO, Input and PWM to resolve
conflicts for the merge window pull request.

Input: remove special handling of id->driver_info when matching

2025-07-02T04:02:58+00:00

evdev has switched to match on EV_SYN instead of relying on non-zero
driver_info field to allow matching to all devices. Remove special
handling from input core.

treewide: Switch/rename to timer_delete[_sync]()

2025-04-05T08:30:12+00:00

timer_delete[_sync]() replaces del_timer[_sync](). Convert the whole tree
over and remove the historical wrapper inlines.

Conversion was done with coccinelle plus manual fixups where necessary.

Input: use guard notation in input core

2024-12-24T06:53:58+00:00

Switch input core to use "guard" notation when acquiring spinlocks and
mutexes to simplify the code and ensure that locks are automatically
released when control leaves critical section.

Pull input updates from Dmitry Torokhov:

 - support for NT36672A touchscreen added to novatek-nvt-ts driver

 - a change to ads7846 driver to prevent XPT2046 from locking up

 - a change switching platform input dirves back to using remove()
   method (from remove_new())

 - updates to a number of input drivers to use the new cleanup
   facilities (__free(...), guard(), and scoped-guard()) which ensure
   that the resources and locks are released properly and automatically

 - other assorted driver cleanups and fixes.

Input: introduce notion of passive observers for input handlers

2024-11-05T22:19:47+00:00

Sometimes it is useful to observe (and maybe modify) data coming from
an input device, but only do that if there are other users of such input
device. An example is touchpad switching functionality on Lenovo IdeaPad
Z570 where it is desirable to suppress events coming from the touchpad
if user toggles touchpad on/off button (on this laptop the firmware does
not stop the device).

Introduce notion of passive observers for input handlers to solve this
issue. An input handler marked as passive observer behaves exactly like
any other input handler or filter, but with one exception: it does not
open/start underlying input device when attaching to it.
