2022-09-14dt-bindings: input: Convert mtk-pmic-keys to DT schemaAngeloGioacchino Del Regno
Convert the mtk-pmic-keys to DT schema format. The old binding was missing documentation for key press/release interrupts, even though it was supported in hardware and driver, so support for the same was added during the conversion.

2022-09-14Input: synaptics - enable InterTouch for the ThinkPad P1 G3Lyude Paul
Noticed this while trying to debug some unrelated issues: this laptop has the ability to use rmi4 but doesn't by default. So let's fix that. Tested locally, including mouse buttons, on my ThinkPad P1 G3. This might also enable the X1 Extreme G3, but I don't have such a system to test locally (presumably Mark can chime in if that's the case).

2022-09-14Input: iqs7222 - set all ULP entry masks by defaultJeff LaBundy
Some devices expose an ultra-low-power (ULP) mode entry mask for each channel. If the mask is set, the device cannot enter ULP so long as the corresponding channel remains in an active state. The vendor has advised setting the mask for any disabled channel. To accommodate this suggestion, initially set all masks and then clear them only if specified in the device tree.

2022-09-06Input: xpad - add support for XBOX One Elite paddlesChristopher Crockett
An effort has been made to support every official model and firmware version I could track down info on. The following controllers _should_ have working paddles with this PR: - Xbox Elite (**untested**) - Xbox Elite Series 2 on early firmwares (**untested**) - Xbox Elite Series 2 on v4 firmwares (Tested v4.8.1908.0) - Xbox Elite Series 2 on v5 pre-BLE firmwares (**untested**) - Xbox Elite Series 2 on v5 post-BLE firmwares (Tested v5.13.3143.0) This patch also introduces correct handling for the Elite 1 controller and properly suppresses paddle inputs when using a custom profile slot. Starting with firmware v5.11, certain inputs for the Elite 2 were moved to an extra packet that is not enabled by default. We must first manually enable this extra packet in order to correctly process paddle input data with these later firmwares.

2022-09-06Input: xpad - fix wireless 360 controller breaking after suspendCameron Gutman
Suspending and resuming the system can sometimes cause the out URB to get hung after a reset_resume. This causes LED setting and force feedback to break on resume. To avoid this, just drop the reset_resume callback so the USB core rebinds xpad to the wireless pads on resume if a reset happened. A nice side effect of this change is the LED ring on wireless controllers is now set correctly on system resume.

2022-08-30Input: adp5588-keys - support gpi key events as 'gpio keys'Nuno Sá
This change replaces the support for GPIs as key event generators. Instead of reporting the events directly, we add a gpio based irqchip so that these events can be consumed by keys defined in the gpio-keys driver (as it's goal is indeed for keys on GPIOs capable of generating interrupts). With this, the gpio-adp5588 driver can also be dropped. The basic idea is that all the pins that are not being used as part of the keymap matrix can be possibly requested as GPIOs by gpio-keys (it's also fine to use these pins as plain interrupts though that's not really the point). Since the gpiochip now also has irqchip capabilities, we should only remove it after we free the device interrupt (otherwise we could, in theory, be handling GPIs interrupts while the gpiochip is concurrently removed). Thus the call 'adp5588_gpio_add()' is moved and since the setup phase also needs to come before making the gpios visible, we also need to move 'adp5588_setup()'. While at it, always select GPIOLIB so that we don't need to use #ifdef guards.

2022-08-16i2c: Make remove callback return voidUwe Kleine-König
The value returned by an i2c driver's remove function is mostly ignored. (Only an error message is printed if the value is non-zero that the error is ignored.) So change the prototype of the remove function to return no value. This way driver authors are not tempted to assume that passing an error to the upper layer is a good idea. All drivers are adapted accordingly. There is no intended change of behaviour, all callbacks were prepared to return 0 before.

2022-08-16gpio: pca953x: Make platform teardown callback return voidUwe Kleine-König
All platforms that provide a teardown callback return 0. New users are supposed to not make use of platform support, so there is no functionality lost.

2022-08-16leds: lm3601x: Improve error reporting for problems during .remove()Uwe Kleine-König
Returning an error value in an i2c remove callback results in a generic error message being emitted by the i2c core, but otherwise it doesn't make a difference. The device goes away anyhow and the devm cleanups are called. So instead of triggering the generic i2c error message, emit a more helpful message if a problem occurs and return 0 to suppress the generic message. This patch is a preparation for making i2c remove callbacks return void.

The mutex might still be in use until the devm cleanup callback devm_led_classdev_flash_release() is called. This only happens some time after lm3601x_remove() completed.

2022-08-16leds: lm3697: Remove duplicated error reporting in .remove()Uwe Kleine-König
Returning an error value from an i2c remove callback results in an error message being emitted by the i2c core, but otherwise it doesn't make a difference. The device goes away anyhow and the devm cleanups are called. As lm3697_remove() already emits an error message on failure and the additional error message by the i2c core doesn't add any useful information, don't pass the error value up the stack. Instead continue to clean up and return 0. This patch is a preparation for making i2c remove callbacks return void.
