Thx for clarificationIf that is all you got of warnings you don't need to worry.
Those are all dtb warnings. It means that the dtsi-files are not quite following the format rules, but it's always been like that for qcom dtsi's.
Yes, i awared of this too, i have some experience in this part on my old device, and in fact i found a comprehensive guide to compile the kernel of my current device, so should be no problem i guess, thxAfter you unlock bootloader, it should be fine, judging from a compilation perspective. Sometimes the official source lacks things, which could make the kernel either not work, or only partially work.
