Hans de Goede 6f29d3b277 Input: gpio_keys_polled - add support for abs/rel axis
This changAdd support for EV_ABS / EV_REL events to the gpio-keys-polled driver.


The driver already allows specifying what type of events (key / rel / abs)
a button generates when pressed, but for rel / abs axis we also need to
specify which value this specific gpio represents.

One use case is digital joysticks / direction-pads which are hooked up to
gpio, in this case we've left and right buttons which we want to map to
EV_ABS, ABS_X and we want generate events for left with a value of -1 and
for right with a value of +1 (and similar for up / down and ABS_Y).
