Merge tag 'input-for-v5.20-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - changes to input core to properly queue synthetic events (such as
   autorepeat) and to release multitouch contacts when an input device
   is inhibited or suspended

 - reworked quirk handling in i8042 driver that consolidates multiple
   DMI tables into one and adds several quirks for TUXEDO line of
   laptops

 - update to mt6779 keypad to better reflect organization of the
   hardware

 - changes to mtk-pmic-keys driver preparing it to handle more variants

 - facelift of adp5588-keys driver

 - improvements to iqs7222 driver

 - adjustments to various DT binding documents for input devices

 - other assorted driver fixes.
