Writing comments in device tree files is the same as writing comments in C, with the same syntax. As can be seen below, you can choose to comment out sections by using /* and */, or you can comment out lines using //.
As mentioned previously, device tree files can use #include to include .dtsi, .dts, as well as C header files. This means macros can be used in device tree files, as seen above. Such is the case with many device tree files in the arch/arm/boot/dts directory.
