Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
Pull input subsystem updates from Dmitry Torokhov:
"- we finally merged driver for USB version of Synaptics touchpads
(I guess most commonly found in IBM/Lenovo keyboard/touchpad combo);
- a bunch of new drivers for embedded platforms (Cypress
touchscreens, DA9052 OnKey, MAX8997-haptic, Ilitek ILI210x
touchscreens, TI touchscreen);
- input core allows clients to specify desired clock source for
timestamps on input events (EVIOCSCLOCKID ioctl);
- input core allows querying state of all MT slots for given event
code via EVIOCGMTSLOTS ioctl;
- various driver fixes and improvements."
