Merge tag 'input-for-v6.2-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - a new driver for Cypress Generation 5 touchscreens

 - a new driver for Hynitron cstxxx touchscreens

 - a new driver for Himax hx83112b touchscreen

 - I2C input devices have been converted to use i2c's probe_new()

 - a large number of input devices are now using
   DEFINE_SIMPLE_DEV_PM_OPS and pm_sleep_ptr() and no longer use
   __maybe_unused annotations

 - improvements to msg2638 touchscreen driver to also support msg2138

 - conversion of several input deevine bindings to yaml/DT schema

 - changes to select touch drivers to move handling of wake irqs to the
   PM core

 - other assorted fixes and improvements.
