器件型号：AM623工具/软件：
我正在尝试确定要在 OLDI 接口上使用 LCD 面板的正确器件树设置。 示例和参考资料似乎非常稀缺、似乎需要改用 VOUT 接口、它在我们的电路板上与其他信号绑定在一起。
我找到的最佳参考是：
在 AM62P 上集成 LVDS 面板
我正在查看 DTS 中的各种示例（这是 6.12 内核）、并将所有这些的 DTS 拼在一起、这显然不是 100%正确的。 似乎也有一些从 dss -> dss0 等重命名的内容、但我不清楚这是特定于处理器还是所有 DTS 中没有更新。
当 I boot 时、我得到：
[ 20.932104] platform 30200000.dss：递延探头待定：tidss：OLDI0 无电池板/桥接器。
我不是 100%确定它是什么 — 这里的驱动程序代码是相当粗糙.
DTS 粘贴在此处。 原谅所有评论的部分 — 正如我所说的,它是从不同的部分组装（和剪切和粘贴丢失的缩排）。 请告诉我我可以提供哪些其他信息。
