Device tree error while building kernel

[imankianian]

I get lots of device tree errors while building kernel. It seems there are some labels that are used in some dts files but not defined or included in their headers. I fix them by including the dtsi file which defined the label in the header of dts file, but again I get the same errors for some other labels. Is the device tree complete? Or am I missing something here? Here is an example of the errors I get:

Error: ../arch/arm64/boot/dts/qcom/sdm845-cdp.dtsi:236.1-27 Label or path dsi_r63417_truly_1080_cmd not found
