2023-05-17Input: Switch i2c drivers back to use .probe()Uwe Kleine-König
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.

2023-05-05Input: edt-ft5x06 - add delay after waking upPhilipp Puschmann
The touch controller needs some time to wake-up after setting the wake-up gpio. 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. The datasheet sets the wake-up time to 5 ms, although it is not entirely clear.

2023-05-05Input: cyttsp5 - implement proper sleep and wakeup proceduresMaximilian Weigand
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.

2023-05-01Input: cyttsp4_core - change del_timer_sync() to timer_shutdown_sync()Duoming Zhou
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.

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.

2023-03-17Input: hideep - optionally reset controller work mode to native HiDeep protocolHans de Goede
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.

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.

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.

SIMPLE_DEV_PM_OPS() is deprecated as it requires explicit protection against unused function warnings. The new combination of pm_sleep_ptr() and EXPORT_GPL_SIMPLE_DEV_PMU_OPS() allows the compiler to see the functions, thus suppressing the warning, but still allowing the unused code to be removed. Thus also drop the __maybe_unused markings. It also rolls in the EXPORT_SYMBOL() so that we only export it if CONFIG_PM_SLEEP.

Note that we are replacing an unconditional call to the suspend and resume functions for sleep use cases with one via pm_runtime_force_suspend() / pm_runtime_force_resume() that only do anything to the device if we are not already in the appropriate runtime suspended state. Signed-off-by: Jonathan Cameron <Jonathan.Cameron@huawei.com> -- I 'think' this should be fine in that it can only reduce the number of unnecessary suspends. If anyone can test that would be great.

The majority of all pxa board files has not been touched in a long time, and no users have spoken up in favor of keeping them around. This leaves only support for the platforms that were already converted to DT, as well as the gumstix and spitz/akita/borzoi machines that work in qemu and can still be converted to DT later.

2023-01-09Input: ipaq-micro-ts - use DEFINE_SIMPLE_DEV_PM_OPS() and pm_sleep_ptr()Jonathan Cameron
This driver never used the older SIMPLE_DEV_PM_OPS() but instead just set two of the callbacks directly. Skip that deprecated macro and go straight to the new form that avoids the need for guarding or marking callbacks __maybe_unused. -- It is possible there is some subtle reason why only two of the callbacks normally set by SIMPLE_DEV_PM_OPS() are set. As such, this one needs some closer reading than many of the others.
