Merge tag 'input-for-v5.19-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - a new driver for the Azoteq IQS7222A/B/C capacitive touch controller

 - a new driver for Raspberry Pi Sense HAT joystick

 - sun4i-lradc-keys gained support of R329 and D1 variants, plus it can
   be now used as a wakeup source

 - pm8941-pwrkey can now properly handle PON GEN3 variants; the driver
   also implements software debouncing and has a workaround for missing
   key press events

 - assorted driver fixes and cleanups
