A digital joystick driver needs to report three states per axis: min,
max and neutral. The hardware only have two signals per axis(i.e. up
and down) however. See http://wiki.icomp.de/wiki/DB9-Joystick
This makes gpio-keys pretty much impossible to use for joysticks - as
the driver only

All right, I find it a bit like whacking

Why do we need this new driver when we have gpio-keys driver that can be

While both the device tree binding and the gpio-keys driver could possibly
This series adds a driver for digital joysticks connected
via GPIOs.
Tested on Rasperry Pi and Minnowboard MAX using evtest.
The DSDT AML-code snippet below illustrates how to configure a joystick
on the Minnowboard MAX, using the new _DSD support in the kernel.
