1.我显示器的连接线，插入开发板的一端（公头）连的是b11，b10，a11，a10引脚，怀疑是和开发板的送出端（母头）没有对应上，我想确认把开发板送出端（母头）的A10,A11,B10,B11配置成信号的输出端口不知道怎么弄；
2..我的显示设备插手机正反插都是没有问题的，但是插我们的开发板却没有办法点亮，想请教软件如何自动适配
3.我通过添加打印发现设备插入时，调用到了drivers/gpu/drm/rockchip/cdn-dp-core.c 中的cdn_dp_get_port_lanes()函数，而里面读取到的lane=4，这是否说明开发板没有配置成2lane输出，如果是的，我应该如何配置？我有尝试直接在这个函数里修改成2lane，没有作用。
