Merge tag 'input-for-v6.17-rc0' of git://git.kernel.org/pub/scm/linux/kernel/git/dtor/inputHEADmaster
Pull input updates from Dmitry Torokhov:
- updates to several drivers consuming GPIO APIs to use setters
returning error codes
- an infrastructure allowing to define "overlays" for touchscreens
carving out regions implementing buttons and other elements from a
bigger sensors and a corresponding update to st1232 driver
- an update to AT/PS2 keyboard driver to map F13-F24 by default
- Samsung keypad driver got a facelift
- evdev input handler will now bind to all devices using EV_SYN event
instead of abusing id->driver_info
- two new sub-drivers implementing 1A (capacitive buttons) and 21
(forcepad button) functions in Synaptics RMI driver
- support for polling mode in Goodix touchscreen driver
- support for support for FocalTech FT8716 in edt-ft5x06 driver
- support for MT6359 in mtk-pmic-keys driver
- removal of pcf50633-input driver since platform it was used on is
gone
- new definitions for game controller "grip" buttons (BTN_GRIP*) and
corresponding changes to xpad and hid-steam controller drivers
- a new definition for "performance" key
