* Input: add driver for power button on Dell Wyse 3020Lubomir Rintel2020-12-093-0/+181
| | | | | | | | | | | | | | | | | | | | This adds support for the power button attached to the Embedded Controller on a Dell Wyse 3020 "Ariel" board. The Embedded Controller's SPI interface is actually capable sending and receiving the PS/2 keyboard and mouse protocol data, which looks like a good fit for a serio driver. Howerver, I don't know of any machines where this is actually used. My board only has a single power button and no way to connect an actual keyboard or a mouse. Using the atkbd driver with serio would be an overkill and would be inconvenient for the userspace. Therefore this driver registers an input device that is only capable of reporting the power button presses and releases.

* Input: gtco - remove driverDmitry Torokhov2020-12-093-1056/+0
| | | | | | | | | | | | | | | | The driver has its own HID descriptor parsing code, that had and still has several issues discovered by syzbot and other tools. Ideally we should move the driver over to the HID subsystem, so that it uses proven parsing code. However the devices in question are EOL, and GTCO is not willing to extend resources for that, so let's simply remove the driver. Note that our HID support has greatly improved over the last 10 years, we may also consider reverting 6f8d9e26e7de ("hid-core.c: Adds all GTCO CalComp Digitizers and InterWrite School Products to blacklist") and see if GTCO devices actually work with normal HID drivers.

* Input: Add "inhibited" propertyPatrik Fimml2020-12-021-7/+105
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Userspace might want to implement a policy to temporarily disregard input from certain devices, including not treating them as wakeup sources. An example use case is a laptop, whose keyboard can be folded under the screen to create tablet-like experience. The user then must hold the laptop in such a way that it is difficult to avoid pressing the keyboard keys. It is therefore desirable to temporarily disregard input from the keyboard, until it is folded back. This obviously is a policy which should be kept out of the kernel, but the kernel must provide suitable means to implement such a policy. This patch adds a sysfs interface for exactly this purpose. To implement the said interface it adds an "inhibited" property to struct input_dev, and effectively creates four states a device can be in: closed uninhibited, closed inhibited, open uninhibited, open inhibited. It also defers calling driver's ->open() and ->close() to until they are actually needed, e.g. it makes no sense to prepare the underlying device for generating events (->open()) if the device is inhibited. uninhibit closed <------------ closed uninhibited ------------> inhibited | ^ inhibit | ^ 1st | | 1st | | open | | open | | | | | | | | last | | last | | close | | close v | uninhibit v | open <------------ open uninhibited ------------> inhibited The top inhibit/uninhibit transition happens when users == 0. The bottom inhibit/uninhibit transition happens when users > 0. The left open/close transition happens when !inhibited. The right open/close transition happens when inhibited. Due to all transitions being serialized with dev->mutex, it is impossible to have "diagonal" transitions between closed uninhibited and open inhibited or between open uninhibited and closed inhibited. No new callbacks are added to drivers, because their open() and close() serve exactly the purpose to tell the driver to start/stop providing events to the input core. Consequently, open() and close() - if provided - are called in both inhibit and uninhibit paths.

| | | | | | | | | | | | | | | | | | | | | | | | | In omap4_keypad_probe, the patch fix several bugs. 1) pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to pm_runtime_put_noidle will result in reference leak. 2) In err_unmap, forget to disable runtime of device, pm_runtime_enable will increase power disable depth. Thus a pairing decrement is needed on the error handling path to keep it balanced. 3) In err_pm_disable, it will call pm_runtime_put_sync twice not one time. To fix this we factor out code reading revision and disabling touchpad, and drop PM reference once we are done talking to the device.
