As far as I can tell, there is no way to specify values for ABS-"keys" in the
device tree binding.
While both the device tree binding and the gpio-keys driver could possibly be adapted to
support this, it makes sense to me to describe joysticks in a separate binding and keep
the driver implementations apart.
In addition to this, auto-repeat and the sys fs disable interface for individual keys
does not make sense for joysticks.
In my mind, keyboards and joysticks are different enough.
Thanks for looking at this,
Hans
