Merge tag 'input-for-v6.18-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - Conversions to yaml/json schema and fixes for input-related device
   tree bindings

 - New drivers:
     - Awinic AW86927 haptic chip
     - Hynitron CST816x series controller
     - Himax HX852x(ES) touchscreen controller

 - Fix uinput to not leak kernel memory via a gap in
   uinput_ff_upload_compat structure

 - Prevent overflow in pressure calculation in tsc2007 driver causing
   phantom touches

 - Make the Atmel maxTouch driver support generic touchscreen
   configuration (flip, rotate, etc)

 - Drop support for platform data in tca8418_keypad, pxa27x-keypad,
   spear-keyboard and twl4030_keypad drivers, they all now rely on
   generic device properties for configuration

 - Other assorted changes and fixes
