2023-05-17Input: Switch i2c drivers back to use .probe()Uwe Kleine-König92-92/+92
After commit b8a1a4cd5a98 ("i2c: Provide a temporary .probe_new() call-back type"), all drivers being converted to .probe_new() and then 03c835f498b5 ("i2c: Switch .probe() to not take an id parameter") convert back to (the new) .probe() to be able to eventually drop .probe_new() from struct i2c_driver.

2023-05-11Input: soc_button_array - add invalid acpi_index DMI quirk handlingHans de Goede1-0/+30
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.

Without having a delay after wake-up probing regularly fails in edt_ft5x06_ts_identify() with an error (i.e. EREMOTEIO) that was caused by a failed i2c transfer.

2023-05-05Input: cyttsp5 - implement proper sleep and wakeup proceduresMaximilian Weigand1-0/+77
The touchscreen can be put into a deep sleep state that prevents it from emitting touch irqs. Put the touchscreen into deep sleep during suspend if it is not marked as a wakeup source. This also fixes a problem with the touchscreen getting unresponsive after system resume when a falling edge trigger is used for the interrupt. When left on during suspend, the touchscreen would pull the interrupt line down in response to touch events, leaving the interrupt effectively disabled after resume.

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.

2023-05-01Input: uinput - allow injecting event timesBiswarup Pal1-0/+34
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.

2023-05-01Input: cyttsp4_core - change del_timer_sync() to timer_shutdown_sync()Duoming Zhou1-2/+1
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.

2023-05-01Input: drv260x - fix magnitude handlingLuca Weiss1-6/+7
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.

This commit explicitly disables the audio interface the same way the official driver does. This is needed for some controllers, such as the PowerA Enhanced Wired Controller for Series X|S (0x20d6:0x200e) to report the guide button.

2023-04-14Input: xpad - add constants for GIP interface numbersVicki Pfau1-1/+4
Wired GIP devices present multiple interfaces with the same USB identification other than the interface number. This adds constants for differentiating two of them and uses them where appropriate Signed-off-by: Vicki Pfau <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Dmitry Torokhov <[email protected]>
2023-04-13Input: cyttsp5 - fix sensing configuration data structurehrdl1-0/+1
Prior to this patch, the sensing configuration data was not parsed correctly, breaking detection of max_tch. The vendor driver includes this field. This change informs the driver about the correct maximum number of simultaneous touch inputs. Tested on a Pine64 PineNote with a modified touch screen controller firmware.

2023-04-02Input: edt-ft5x06 - calculate points data length only onceDario Binacchi1-28/+28
It is pointless and expensive to calculate data in the interrupt that depends on the type of touchscreen, which is detected on the driver probe and cannot then be changed. So calculate the size of the data buffer on the driver probe, as well as the data retrieval command, and then use them in the ISR.

2023-04-02Input: tsc2007 - enable cansleep pendown GPIOBenjamin Bara1-15/+2
When a hard IRQ is triggered, the soft IRQ, which decides if an actual pen down happened, should always be triggered. This enables the usage of "can_sleep" GPIO chips as "pen down" GPIO, as the value is not read during the hard IRQ anymore. This might be the case if the GPIO chip is an expander behind i2c.
