Subject: [PATCH 9/9] arm64: dts: rockchip: Add the Video-Demo overlay for Lion Haikou
From: Heiko Stuebner <heiko.stuebner@...rry.de>
The video-demo adapter also works on the Lion SoM when running
on a Haikou baseboard, so add an overlay for it.
Signed-off-by: Heiko Stuebner <heiko.stuebner@...rry.de>
