I have a list of drivers that I determined to be likely
unused as well and found a few more input drivers
that were unused in 2022:

CONFIG_KEYBOARD_ADP5520/CONFIG_PMIC_ADP5520
CONFIG_KEYBOARD_ADP5589
CONFIG_INPUT_AD714X
CONFIG_TOUCHSCREEN_AD7877

As far as I can tell, these all lost their last device
definition, or they never had one and are impossible to
be used with device tree data.
