2023-07-11Input: pm8941-powerkey - fix debounce on gen2+ PMICsCaleb Connolly
[ Upstream commit 8c9cce9cb81b5fdc6e66bf3f129727b89e8daab7 ] Since PM8998/PM660, the power key debounce register was redefined to support shorter debounce times. On PM8941 the shortest debounce time (represented by register value 0) was 15625us, on PM8998 the shortest debounce time is 62us, with the default being 2ms. Adjust the bit shift to correctly program debounce on PM8998 and newer.

2023-07-11Input: cyttsp4_core - change del_timer_sync() to timer_shutdown_sync()Duoming Zhou
[ Upstream commit dbe836576f12743a7d2d170ad4ad4fd324c4d47a ] 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.

2023-06-28Input: soc_button_array - add invalid acpi_index DMI quirk handlingHans de Goede
[ Upstream commit 20a99a291d564a559cc2fd013b4824a3bb3f1db7 ] Some devices have a wrong entry in their button array which points to a GPIO which is required in another driver, so soc_button_array must not claim it. A specific example of this is the Lenovo Yoga Book X90F / X90L, where the PNP0C40 home button entry points to a GPIO which is not a home button and which is required by the lenovo-yogabook driver. Add a DMI quirk table which can specify an ACPI GPIO resource index which should be skipped; and add an entry for the Lenovo Yoga Book X90F / X90L to this new DMI quirk table.

2023-06-14Input: xpad - delete a Razer DeathAdder mouse VID/PID entryIsmael Ferreras Morezuelas
commit feee70f4568650cf44c573488798ffc0a2faeea3 upstream. While doing my research to improve the xpad device names I noticed that the 1532:0037 VID/PID seems to be used by the DeathAdder 2013, so that Razer Sabertooth instance looked wrong and very suspect to me. I didn't see any mention in the official drivers, either. After doing more research, it turns out that the xpad list is used by many other projects (like Steam) as-is [1], this issue was reported [2] and Valve/Sam Lantinga fixed it [3]: [1]: https://github.com/libsdl-org/SDL/blob/dcc5eef0e2395854b254ea2873a4899edab347c6/src/joystick/controller_type.h#L251 [2]: https://steamcommunity.com/app/353380/discussions/0/1743392486228754770/ [3]: https://hg.libsdl.org/SDL/rev/29809f6f0271 (With multiple Internet users reporting similar issues, not linked here) After not being able to find the correct VID/PID combination anywhere on the Internet and not receiving any reply from Razer support I did some additional detective work, it seems like it presents itself as "Razer Sabertooth Gaming Controller (XBOX360)", code 1689:FE00. Leaving us with this: * Razer Sabertooth (1689:fe00) * Razer Sabertooth Elite (24c6:5d04) * Razer DeathAdder 2013 (1532:0037) [note: not a gamepad] So, to sum things up; remove this conflicting/duplicate entry: { 0x1532, 0x0037, "Razer Sabertooth", 0, XTYPE_XBOX360 }, As the real/correct one is already present there, even if the Internet as a whole insists on presenting it as the Razer Sabertooth Elite, which (by all accounts) is not: { 0x1689, 0xfe00, "Razer Sabertooth", 0, XTYPE_XBOX360 }, Actual change in SDL2 referencing this kernel issue: https://github.com/libsdl-org/SDL/commit/e5e54169754ca5d3e86339d968b20126d9da0a15 For more information of the device, take a look here: https://github.com/xboxdrv/xboxdrv/pull/59 You can see a lsusb dump here: https://github.com/xboxdrv/xboxdrv/files/76581/Qa6dBcrv.txt Fixes: f554f619b70 ("Input: xpad - sync device IDs with xboxdrv") Signed-off-by: Ismael Ferreras Morezuelas <swyterzone@gmail.com> Reviewed-by: Cameron Gutman <aicommander@gmail.com> Cc: stable@vger.kernel.org Link: https://lore.kernel.org/r/5c12dbdb-5774-fc68-5c58-ca596383663e@gmail.com Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.org>

2023-03-23Input: i8042 - add TUXEDO devices to i8042 quirk tables for partial fixWerner Sembach
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.

2023-03-19Input: alps - fix compatibility with -funsigned-charmsizanoen
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.

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.

2023-02-03Input: iqs626a - drop unused device node referencesJeff LaBundy
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.

2023-02-03Input: cyttsp5 - fix bitmask for touch buttonsRichard Kjerstadius
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.
