rk3399pro mipi_dsi输出的问题
你好：现在我用rk3399pro开发板开发项目，其中用到mipi_dsi接口输出视频， mipi_dsi接口接了一个lt8912芯片（mipi转hdmi）。
我现在移植mipi_dsi驱动，如下是我的移植操作：
一.由于要用到mipi接口，所以先要在menuconfig里打开mipi。
（1）-> Device Drivers
| -> Graphics support
| -> Rockchip Misc Video drive
| -> LCD Panel Select (rk mipi dsi lcd)
（2）-> Device Drivers
| -> Graphics support
| -> Rockchip Misc Video driver
| -> RockChip display transmitter support
RK32 RGB to DisplayPort transmitter support
Rockchip MIPI DSI support
配置完上面的驱动保存后，打开.config文件，如果文件里面有如下3条数据，说明配置成功。
CONFIG_LCD_MIPI=y
CONFIG_MIPI_DSI=y
CONFIG_RK32_MIPI_DSI=y
还有个驱动需要勾选上
-> Device Drivers
| -> Graphics support
| -> Display Panels---><*> support for simple panel
二打开mipi后，在kernel 目录下执行
make -j8 ARCH=arm64 rk3399pro-firefly-aiojd4.img 命令，编译内核，编译不成功，报如下错误。drivers/built-in.o：在函数‘edp_psr_state’中：/home/wzb/rk3399-pro/Android8.1/AIO-RK3399ProJD4/firenow-oreo-rk3399pro/kernel/drivers/video/rockchip/transmitter/rk32_dp.c:1460：对‘rk_fb_poll_wait_frame_complete’未定义的引用/home/wzb/rk3399-pro/Android8.1/AIO-RK3399ProJD4/firenow-oreo-rk3399pro/kernel/drivers/video/rockchip/transmitter/rk32_dp.c:1460:(.text+0x48e38):

请问下，是否有别的配置项没有配置呢。请不瑟吝教，谢谢。
不需要再配置defconfig，默认的已经支持mipi dsi leung先森 发表于 2020-5-19 14:49

谢谢，我按默认配置，修改rk3399.dtsi文件，&dsi{status="okay"} 。内核运行后，一直打印下述错误：

这个东西不是这样改 的，其实网上也有一些说明，例如
https://blog.csdn.net/manshq163com/article/details/54598455
你这个驱动应该就是让他上电初始化，然后dts按照mipi dsi的修改方法去配置1080P的timing以及一些必要的command，具体还是要看这个IC的datasheet。
