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

-	  This driver implements basic keypad functionality
-	  for keys connected through TCA6416/TCA6408A IO expanders.
-
-	  Say Y here if your device has keys connected to
-	  TCA6416/TCA6408A IO expander. Your board-specific setup logic
-	  must also provide pin-mask details(of which TCA6416 pins
-	  are used for keypad).
-
-	  If enabled the entire TCA6416 device will be managed through
-	  this driver.
