想添加mipi 显示, 按照官网的wiki:
- 在arch/arm/configs/firefly_linux_defconfig 中添加了三个mipi的配置,
- 复制 kernel/include/dt-bindings/display/screen-timing/lcd-h546dlb01-mipi.dtsi 到arch/arm/boot/dts/ 路径下
- 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:
