Pull input layer updates from Dmitry Torokhov: - evdev interface has been adjusted to extend the life of timestamps on 32 bit systems to the year of 2108 - Synaptics RMI4 driver's PS/2 guest handling ha beed updated to improve chances of detecting trackpoints on the pass-through port - mms114 touchcsreen controller driver has been updated to support generic device properties and work with mms152 cntrollers - Goodix driver now supports generic touchscreen properties - couple of drivers for AVR32 architecture are gone as the architecture support has been removed from the kernel - gpio-tilt driver has been removed as there are no mainline users and the driver itself is using legacy APIs and relies on platform data - MODULE_LINECSE/MODULE_VERSION cleanups * 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input: (45 commits) Input: goodix - use generic touchscreen_properties Input: mms114 - fix typo in definition Input: mms114 - use BIT() macro instead of explicit shifting Input: mms114 - replace mdelay with msleep Input: mms114 - add support for mms152 Input: mms114 - drop platform data and use generic APIs Input: mms114 - mark as direct input device Input: mms114 - do not clobber interrupt trigger Input: edt-ft5x06 - fix error handling for factory mode on non-M06 Input: stmfts - set IRQ_NOAUTOEN to the irq flag Input: auo-pixcir-ts - delete an unnecessary return statement Input: auo-pixcir-ts - remove custom log for a failed memory allocation Input: da9052_tsi - remove unused mutex Input: docs - use PROPERTY_ENTRY_U32() directly Input: synaptics-rmi4 - log when we create a guest serio port Input: synaptics-rmi4 - unmask F03 interrupts when port is opened Input: synaptics-rmi4 - do not delete interrupt memory too early Input: ad7877 - use managed resource allocations Input: stmfts,s6sy671 - add SPDX identifier Input: remove atmel-wm97xx touchscreen driver ...

-Driver for tilt-switches connected via GPIOs
-============================================
-
-Generic driver to read data from tilt switches connected via gpios.
-Orientation can be provided by one or more than one tilt switches,
-i.e. each tilt switch providing one axis, and the number of axes
-is also not limited.
-
-
-Data structures
----------------
-
-The array of struct gpio in the gpios field is used to list the gpios
-that represent the current tilt state.
-
-The array of struct gpio_tilt_axis describes the axes that are reported
-to the input system. The values set therein are used for the
-input_set_abs_params calls needed to init the axes.
-
-The array of struct gpio_tilt_state maps gpio states to the corresponding
-values to report. The gpio state is represented as a bitfield where the
-bit-index corresponds to the index of the gpio in the struct gpio array.
-In the same manner the values stored in the axes array correspond to
-the elements of the gpio_tilt_axis-array.
-
-
-Example
--------
-
-Example configuration for a single TS1003 tilt switch that rotates around
-one axis in 4 steps and emits the current tilt via two GPIOs::
