dt-bindings: display: rockchip: Add schema for RK3588 DW
From: Heiko Stuebner <heiko.stuebner@...> Date: Wed, 6 Nov 2024 10:15:29 +0100
Commit-Message
The Display Serial Interface 2 (DSI-2) is part of a group of communication protocols defined by the MIPI Alliance. The RK3588 implements this specification in its two MIPI DSI-2 Host Controllers that are based on a new Synopsys IP. Tested-by: Dmitry Yashin <dmt.yashin@...> Reviewed-by: Rob Herring (Arm) <robh@...> Signed-off-by: Heiko Stuebner <heiko.stuebner@...>
