Merge tag 'input-for-v6.6-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/input

Pull input updates from Dmitry Torokhov:

 - a new driver for Azoteq IQS7210A/7211A/E touch controllers

 - support for Azoteq IQS7222D variant added to iqs7222 driver

 - support for touch keys functionality added to Melfas MMS114 driver

 - new hardware IDs added to exc3000 and Goodix drivers

 - xpad driver gained support for GameSir T4 Kaleid Controller

 - a fix for xpad driver to properly support some third-party
   controllers that need a magic packet to start properly

 - a fix for psmouse driver to more reliably switch to RMI4 mode on
   devices that use native RMI4/SMbus protocol

 - a quirk for i8042 for TUXEDO Gemini 17 Gen1/Clevo PD70PN laptops

 - multiple drivers have been updated to make use of devm and other
   newer APIs such as dev_err_probe(), devm_regulator_get_enable(), and
   others.
