Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input
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 Input: synaptics-rmi4 - using logical instead of bitwise AND Input: powermate - fix oops with malicious USB descriptors Input: snvs_pwrkey - fix returned value check of syscon_regmap_lookup_by_phandle() MAINTAINERS: add devicetree bindings to Input Drivers section Input: synaptics-rmi4 - add device tree support to the SPI transport driver Input: synaptics-rmi4 - add SPI transport driver Input: synaptics-rmi4 - add support for F30 Input: synaptics-rmi4 - add support for F12 Input: synaptics-rmi4 - add device tree support for 2d sensors and F11 Input: synaptics-rmi4 - add support for 2D sensors and F11 Input: synaptics-rmi4 - add device tree support for RMI4 I2C devices Input: synaptics-rmi4 - add I2C transport driver Input: synaptics-rmi4 - add support for Synaptics RMI4 devices Input: ad7879 - add device tree support Input: ad7879 - fix default x/y axis assignment Input: ad7879 - move header to platform_data directory Input: ts4800 - add hardware dependency Input: cyapa - fix for losing events during device power transitions Input: sh_keysc - remove dependency on SUPERH ...
