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."
