连接方式为：cpu -> 941 -> 同轴线 -> 924 -> 1280*800 lvds
一，按941寄存器配置例子设置，如下图所示
941寄存器如下：

我最初分别用941 ，924的pattern 模式测试lcd，显示均没问题。
然后，我用cpu输出的dsi，发现花屏，并且941的状态寄存器显示dsi error，dsi phy error，我不知道怎么解决？
二是，941进行probe时，系统的dsi部分还没输出dsi信号。
所以，我在941 probe时，使用schedule_delayed_work延迟给941 初始化寄存器，确保dsi输出之后，再init 941寄存器，但失败了
