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

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
