使用以下示例 dts 叠加 (.dtso)，在克隆模式下启用单链路 OLDI。代码也可以从 Beyond SDK GitHub 页面 获得。

• 每个 LCD 供应商都有唯一的时序参数，并在 DTS 文件中针对（例如）Rocktech LCD 定义了一个兼容字段，如上所示。兼容字段映射到名为 panel-simple.c 的文件。文件位于内核目录 drivers/gpu/drm/panel 下。在 panel-simple.c 文件中，时序参数由 SK-LCD1 供应商定义。
• 对于克隆模式下的单链路 OLDI，使用 dss0 将视频信号传输至 OLDI TX0 和 OLDI TX1。在克隆模式下，两个 olditx IP 均已启用。因此，dss0 vp0 下有两个端点。
• 这种模式与 OLDI（双链路）模式的区别在于 dual-lvds-odd-pixels 和 dual-lvds-even-pixels，同时保留强制实施单链路克隆模式的配套节点。
• 有两个独立的显示节点，每个节点都有一个端口 (port@0)。
