各位好：
我在i.MX8QXP上适配一个MIPI-DSI接口1280*720 4*lane的显示器，需求时钟应该在64MHz左右，但是我在配置的时候，发现时钟最小只能配置到74.25MHz，当我配置时钟小于74.25MHz时，启动log如下，显示器并不能正常工作。

当配置时钟大于74.25MHz时，启动log如下。显示器相关初始化成功，但是显示效果仍然不正常。

我在论坛上看到一些相关的讨论
[drm] Cannot find any crtc or sizes
Display pixel clock limitation to 74.25 MHz
请问一下，我需要做什么配置，才能正确配置DSI的工作时钟为64MHz？
谢谢
