2017-02-20Input: zet6223 - export OF device ID as module aliasesJavier Martinez Canillas
The I2C core always reports a MODALIAS of the form i2c:<foo> even if the device was registered via OF, this means that exporting the OF device ID table device aliases in the module is not needed. But in order to change how the core reports modaliases to user-space, it's better to export it. Before this patch: $ modinfo drivers/input/touchscreen/zet6223.ko | grep alias alias: i2c:zet6223 After this patch: $ modinfo drivers/input/touchscreen/zet6223.ko | grep alias alias: of:N*T*Czeitec,zet6223C* alias: of:N*T*Czeitec,zet6223 alias: i2c:zet6223 Signed-off-by: Javier Martinez Canillas <javier@osg.samsung.com> Signed-off-by: Dmitry Torokhov <dmitry.torokhov@gmail.com>

Instead of supporting legacy platform data (of which we have no mainline users) and OF-based properties, let's switch to generic device properties. This will still allow legacy boards to use the driver (by defining property sets and attaching them to the drivers) and will simplify probe and make driver usable on ACPI-based systems as well.

2017-02-12Input: tsc2004/5 - fix regulator handlingDmitry Torokhov
In case of an optional regulator missing, regulator core will return ERR_PTR(-ENOENT) and not NULL, so the check for missing regulator is incorrect. Also, the regulator is not optional, it may simply be missing from platform description, so let's use devm_regulator_get() and rely on regulator core to give us dummy supply when real one is not available.

2017-02-09Input: joydev - do not report stale values on first openRaphael Assenat
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: psmouse - add a custom serio protocol to send extra informationBenjamin Tissoires
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.
