Title: mipi_dphy0 enabling error in dts file
I'm trying enable to mipi dsi on RK3566-PC.
For that I'am using this documantation. https://download.t-firefly.com/product/Board/Common/Document/Developer/Rockchip_Developer_Guide_DRM_Panel_Porting_CN.pdf
In this documantation there is a step for  enable to mipi_dphy0.
When I change the device tree for enable to mipi_dphy0, I take a kernel dts build error.

When I added the code in following file to kernel/arch/arm64/boot/dts/rockchip/rk3566-firefly-roc-pc-mipi101_M101014_BE45_A1.dts file,
&mipi_dphy0 {
status = "okay";
}

&mipi_dphy1 {
status = "disabled";
}

I took the error at following line:

scripts/kconfig/conf  --syncconfig Kconfig

How can I enable the mipi_dsi0 like says on documentation ?

syntax error because you are missing a ";" at end of "}"
BUT this is not the point.
There's no mipi_dphy nodes in RK356x but video_phy instead. The doc you read is not suitable for RK356X
You can find more accurate docs under docs/ in SDK
rk3566-firefly-roc-pc-mipi101_M101014_BE45_A1.dts is already well configured, you can find video_phy0 is enabled in it.
So you don't need to modify anything about dts, mipi dsi0 works if you choose the right mk file when building, for example:

# choose to build ubuntu firmware with mipi support
./build.sh roc-rk3566-pc-mipi-ubuntu.mk
# start build
./build.sh
