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

Pull input subsystem updates from Dmitry Torokhov:

 - a big update from Mauro converting input documentation to ReST format

 - Synaptics PS/2 is now aware of SMBus companion devices, which means
   that we can now use native RMI4 protocol to handle touchpads, instead
   of relying on legacy PS/2 mode.

 - we removed support from BMA180 accelerometer from input devices as it
   is now handled properly by IIO

 - update to TSC2007 to corretcly report pressure

 - other miscellaneous driver fixes.
