With the SM8650-HDK, a Display Card kit can be connected to provide a VTDR6130 display with Goodix Berlin Touch controller. In order to route the DSI lanes to the connector for the Display Card kit, a switch must be changed on the board. The HDMI nodes are disabled since the DSI lanes are shared with the DSI to HDMI transceiver. Add support for this card as an overlay and apply it it at build-time to the sm8650-hdk dtb.
