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.
