标题: rk3399pro mipi输出dts配置为问题
各位大神好，我现在用rk3399pro开发板，用的是mipi0接口接lt8912(mipi转hdmi芯片)，我现在配置dts文件，让mipi0 接口输出mipi信号，我的dts配置如下：

修改rk3399.dtsi文件，

把 vopl节点的 status 设为"okay"

dsi: dsi@ff960000 {
compatible = "rockchip,rk3399-mipi-dsi";
reg = <0x0 0xff960000 0x0 0x8000>;
interrupts = <GIC_SPI 45 IRQ_TYPE_LEVEL_HIGH 0>;
clocks = <&cru SCLK_DPHY_PLL>, <&cru PCLK_MIPI_DSI0>,
<&cru SCLK_DPHY_TX0_CFG>;
clock-names = "ref", "pclk", "phy_cfg";
power-domains = <&power RK3399_PD_VIO>;
resets = <&cru SRST_P_MIPI_DSI0>;
reset-names = "apb";
rockchip,grf = <&grf>;
status = "okay";
#address-cells = <1>;
#size-cells = <0>;

把dsi节点的status设为"okay"

编译内核：
用的命令为：
make ARCH=arm64 firefly_defconfig
make -j8 ARCH=arm64 rk3399pro-firefly-aiojd4.img(用的是rk3399pro-firefly-aiojd4.dts )
内核运行，LOG打印出的错误如下所示：

请问：
（1）这种情况是mipi的dts配置不正确，rk3399pro mipi输出正确的dts配置是怎样的呢？
（2）rk3399pro 官方源码中，有一个rk3399pro-evb-mipi.dts文件，这个文件是否是正确的mipi dts配置。

（3）有大神做的rk3399pro mipi接口接lt8912(mipi转hdmi芯片)的项目吗，这种情况怎样配置mipi输出呢（是否把lt8912看做一个LCD屏）。
谢谢大家的不瑟吝教。

楼主你好，我也遇到了类似的问题，我想配置两个gpio做中断接收和使能，用的pro aiojd4的开发板，我是修改的rk3399-firefly-dts文件，编译内核命令和楼主一样，但是结果配置失败，
请问楼主解决问题了吗，可以分享下吗
