打开lcdc显示就会打印：rk3288-lcdc lcdc0: blank mode:0
可以把指令贴出来看看
比较长我把整个屏参贴上来把，请看！

打开lcdc显示就会打印：rk3288-lcdc lcdc0: blank mode:0
可以把指令贴出来看看

为什么点双MIPI屏的时候会出现这个LOG信息？

[ 1.427218] rk_fb_trsm_ops_get:un supported transmitter:0!
这个没什么关系，这个对应的是SCREEN_NULL
<0x39 0x11>;<0x39 0x29>中：0x39改成0x05试试
双MIPI的话把rockchip,dsi_id = <0>;这个改成rockchip,dsi_id = <2>;
参考：Documentation/devicetree/bindings/video/rockchip_mipidsi_lcd.txt

按照您这个更改了效果还是一样的！
没有显示。MIPI的这些初始化命令都没写进去，写进去的话屏上的几个电压会改变的
rockchip,cmd_debug = <0>;
改为1,看看有没有指令打印的信息

rockchip,cmd_debug = ;

你的意思是看有没有写入的指令把，有的，我在驱动里面直接打开的！

刚刚好我调了一个双MIPI这个分辨率的驱动，参考一下，看看有没有什么配置差异或者先把clk降一些，改成clock-frequency = <128000000>;

HI 屏参这块就寄存器的值和IO的区别，您是否可以将你那边点这个双MIPI屏的整个更改的PATCH上传我看下，我看下是否是我哪里没有更改到，我目前的更改都是按照RockChip_DSS Development Guide v1.2.pdf这个文档里面说的配置来更改的！
