标题: ubuntu 内核编译添加mipi 配置编译失败
想添加mipi 显示, 按照官网的wiki:
1. 在arch/arm/configs/firefly_linux_defconfig 中添加了三个mipi的配置,
2. 复制 kernel/include/dt-bindings/display/screen-timing/lcd-h546dlb01-mipi.dtsi 到arch/arm/boot/dts/ 路径下
3. 在rk3288-firefly.dts 中添加了 #include "lcd-h546dlb01-mipi.dtsi ",
在没有添加mipi配置的时候, 编译都正常,编译的ubuntu系统可以运行,
添加mipi时, 编译kernel的时候信息:

看信息是dts文件的对应行存在格式错误，检查下格式问题

嗯，这个是官方提供的lcd dts 文件，我什么都没有改

WIKI上驱动开发部分是基于Android进行说明的，而且也不是说直接使用那个lcd文件。
可以参考SDK的文档进行配置：SDK/docs/Develop reference documents/DISPLAY/Rockchip_DRM_Panel_Porting_Guide_V1.6_20190228.pdf
