Merge tag 'input-for-v6.12-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - support for PixArt PS/2 touchpad

 - updates to tsc2004/5, usbtouchscreen, and zforce_ts drivers

 - support for GPIO-only mode for ADP55888 controller

 - support for touch keys in Zinitix driver

 - support for querying density of Synaptics sensors

 - sysfs interface for Goodex "Berlin" devices to read and write touch
   IC registers

 - more quirks to i8042 to handle various Tuxedo laptops

 - a number of drivers have been converted to using "guard" notation
   when acquiring various locks, as well as using other cleanup
   functions to simplify releasing of resources (with more drivers to
   follow)

 - evdev will limit amount of data that can be written into an evdev
   instance at a given time to 4096 bytes (170 input events) to avoid
   holding evdev->mutex for too long and starving other users

 - Spitz has been converted to use software nodes/properties to describe
   its matrix keypad and GPIO-connected LEDs

 - msc5000_ts, msc_touchkey and keypad-nomadik-ske drivers have been
   removed since noone in mainline have been using them

 - other assorted cleanups and fixes
