Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:
 "Items of note:

   - evdev users can now limit or mask the kind of events they will
     receive.  This will allow applications such as power manager or
     network manager to only be woken when user presses special keys
     such as KEY_POWER or KEY_WIFI and not be bothered with ordinary
     key presses coming from keyboard

   - support for FocalTech FT6236 touchscreen controller

   - support for ROHM BU21023/24 touchscreen controller

   - edt-ft5x06 touchscreen driver got a face lift and can now be used
     with FT5506

   - support for Google Fiber TV Box remote controls

   - improvements in xpad driver (with more to come)

   - several parport-based drivers have been switched to the new device
     model

   - other miscellaneous driver improvements"
