2024-11-07Input: ads7846 - add dummy command register clearing cycleMarek Vasut
On STM32MP135F with XPT2046 touch controller attached to SPI bus, it has been observed that the touch controller locks up after Linux kernel has finished booting. Adding a dummy cycle on the SPI bus seems to mitigate the lock up. The XPTEK XPT2046 controller seems to be an identical clone of TI TSC2046, the datasheet seems to be a clone of the TI part as well, text seem to be word to word identical, except all the pictures have been drawn again. This touch controller is present e.g. on WaveShare 3.2inch RPi LCD (B) panel, the DTO provided by WaveShare uses 50 kHz SPI clock for this touch controller, which is unusually low and possibly might have been used as some sort of workaround for an issue. The SPI LCD on the same bus uses 16 MHz clock. SPI bus DT properties spi-cs-setup-delay-ns, spi-cs-hold-delay-ns, spi-cs-inactive-delay-ns, spi-rx-delay-us, spi-tx-delay-us set to range of 500ns..5us seem to have no impact on the behavior of the touch controller, the lock up always occurs. The STM32MP13xx SPI controller users GPIO control for the nCS pins. Since the dummy cycle happens after the controller has been put into power down mode and both ADC and REF regulators have been disabled, the cycle should have no impact on the configuration of the controller, i.e. it should be a NOP. It is unclear whether this problem is specific to this cloned XPT2046 controller, or whether this is also present on TSC2046. A test on either TSC2046 or ADS7846 would be very welcome.

2024-11-05Input: introduce notion of passive observers for input handlersDmitry Torokhov
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.

2024-11-02Input: fix regression when re-registering input handlersDmitry Torokhov
Commit d469647bafd9 ("Input: simplify event handling logic") introduced code that would set handler->events() method to either input_handler_events_filter() or input_handler_events_default() or input_handler_events_null(), depending on the kind of input handler (a filter or a regular one) we are dealing with. Unfortunately this breaks cases when we try to re-register the same filter (as is the case with sysrq handler): after initial registration the handler will have 2 event handling methods defined, and will run afoul of the check in input_handler_check_methods(): input: input_handler_check_methods: only one event processing method can be defined (sysrq) sysrq: Failed to register input handler, error -22 Fix this by adding handle_events() method to input_handle structure and setting it up when registering a new input handle according to event handling methods defined in associated input_handler structure, thus avoiding modifying the input_handler structure.

2024-10-24Input: edt-ft5x06 - fix regmap leak when probe failsDmitry Torokhov
The driver neglects to free the instance of I2C regmap constructed at the beginning of the edt_ft5x06_ts_probe() method when probe fails. Additionally edt_ft5x06_ts_remove() is freeing the regmap too early, before the rest of the device resources that are managed by devm are released. Fix this by installing a custom devm action that will ensure that the regmap is released at the right time during normal teardown as well as in case of probe failure. Note that devm_regmap_init_i2c() could not be used because the driver may replace the original regmap with a regmap specific for M06 devices in the middle of the probe, and using devm_regmap_init_i2c() would result in releasing the M06 regmap too early.

2024-10-04Input: serio-raw - fix potential serio port name truncationDmitry Torokhov
When compiling with W=1 the following warnings are triggered: drivers/input/serio/serio_raw.c: In function ‘serio_raw_connect’: drivers/input/serio/serio_raw.c:303:28: error: ‘%ld’ directive output may be truncated writing between 1 and 11 bytes into a region of size 7 [-Werror=format-truncation=] 303 | "serio_raw%ld", (long)atomic_inc_return(&serio_raw_no)); atomic_inc_return() returns an int, so there is no reason to cast it to long and print as such. Fix the issue by removing the cast, printing it as unsigned decimal, and expanding the name from 16 to 20 bytes to accommodate the largest possible port number.

2024-10-04Input: serio_raw - use guard notation for locks and other resourcesDmitry Torokhov
Use guard notation when acquiring mutexes and spinlocks, and when pausing and resuming serio port. Such guard notation makes the code more compact and error handling more robust by ensuring that locks are released in all code paths when control leaves critical section.
