Subject: [PATCH] arm64: dts: rockchip: add adc joystick to Odroid Go Advance
From: Heiko Stuebner <heiko.stuebner@...obroma-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@...obroma-systems.com>

This still needs the iio-joystick driver to get merged first.
