Pull input updates from Dmitry Torokhov:
"The most notable item is addition of support for Synaptics RMI4
protocol which is native protocol for all current Synaptics devices
(touchscreens, touchpads). In later releases we'll switch devices
using HID and PS/2 protocol emulation to RMI4.
You will also get:
- BYD PS/2 touchpad protocol support for psmouse
- MELFAS MIP4 Touchscreen driver
- rotary encoder was moved away from legacy platform data and to
generic device properties API, devm_* API, and can now handle
encoders using more than 2 GPIOs
- Cypress touchpad driver was switched to devm_* API and device
properties
- other assorted driver fixes"
* 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (40 commits)
ARM: pxa/raumfeld: use PROPERTY_ENTRY_INTEGER to define props
