From: Heiko Stuebner <heiko.stuebner@theobroma-systems.com>
Add the now usable adc-joystick node that describes the analog joystick connected to two saradc channels from the rk3326 soc.
Signed-off-by: Heiko Stuebner <heiko.stuebner@theobroma-systems.com> --- This still needs the iio-joystick driver to get merged first. See http://lore.kernel.org/r/20200517194904.34758-1-contact@artur-rojek.eu
