2017-02-09Input: add driver for Zeitec ZET6223Jelle van der Waa5-0/+312
This is a basic driver for the Zeitec ZET6223 I2C touchscreen controllers. The driver does not support firmware loading, which is not required for all tablets which contain this chip.

2017-02-09Input: joydev - do not report stale values on first openRaphael Assenat1-5/+13
Postpone axis initialization to the first open instead of doing it in joydev_connect. This is to make sure the generated startup events are representative of the current joystick state rather than what it was when joydev_connect() was called, potentially much earlier. Once the first user is connected to joydev node we'll be updating joydev->abs[] values and subsequent clients will be getting correct initial states as well. This solves issues with joystick driven menus that start scrolling up each time they are started, until the user moves the joystick to generate events. In emulator menu setups where the menu program is restarted every time the game exits, the repeated need to move the joystick to stop the unintended scrolling gets old rather quickly...

2017-02-09Input: synaptics-rmi4 - forward upper mechanical buttons to PS/2 guestBenjamin Tissoires3-16/+95
On the latest series of ThinkPads, the button events for the TrackPoint are reported through the touchpad itself as opposed to the TrackPoint device. In order to report these buttons properly, we need to forward them to the TrackPoint device and notify psmouse to send the button presses/releases.

2017-02-09Input: synaptics-rmi4 - clean up F30 implementationDmitry Torokhov1-182/+144
This patch does several cleanup changes to F30 code - switch to using BIT() macro - use DIV_ROUND_UP() where appropriate - factor out code setting up and reporting buttons - use single loop when reporting buttons: arithmetic is cheap compared to conditionals and associated branch misprediction.

2017-02-09Input: synaptics - use SERIO_OOB_DATA to handle trackstick buttonsDmitry Torokhov2-14/+13
Instead of using custom method of "passing" extended buttons from the touchpad to trackstick, let's switch to the newly introduced SERIO_OOB_DATA channel. Tested-By: Benjamin Tissoires <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>
2017-02-09Input: psmouse - add a custom serio protocol to send extra informationBenjamin Tissoires3-6/+47
The tracksticks on the Lenovo thinkpads have their buttons connected through the touchpad device. We already fixed that in synaptics.c, but when we switch the device into RMI4 mode to have proper support, the pass-through functionality can't deal with them easily. We add a new PS/2 flag and protocol designed for psmouse. The RMI4 F03 pass-through can then emit a special set of commands to notify psmouse the state of the buttons. This patch implements the protocol in psmouse, while an other will do the same for rmi4-f03. Signed-off-by: Benjamin Tissoires <[email protected]> Signed-off-by: Dmitry Torokhov <[email protected]>

2017-02-01Input: refuse to register absolute devices without absinfoDmitry Torokhov1-0/+6
If device is supposed to send absolute events (i.e. EV_ABS bit is set in dev->evbit) but dev->absinfo is not allocated, then the driver has done something wrong, and we should not register such device. Otherwise we'll crash later, when driver tries to send absolute event.

Usually userspace sends SND_BELL and SND_TONE events, and by the time pwm_beeper_suspend() runs userpsace is already frozen, but theoretically in-kernel users may send these events too, and that may cause pwm_beeper_event() scheduling another work after we canceled it.
