ARM: dts: rockchip: add focaltech touchscreen to
From: Heiko Stuebner <heiko.stuebner@...> Date: Fri, 21 Dec 2018 17:10:12 +0100
Commit-Message
The Edison tablet uses a Focaltech touchscreen, with one speciality that the touchscreen resolution doesn't match the display resolution (1024x768 vs. 1280x600) which userspace will have to compensate for. Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
