It is a bit unwieldy. Perhaps *.dtsp, *.dtsip would be better.

Not without editing all the device tree files; any property (or node)
name the starts with a # must be escaped; changed from "#foo" to "\#foo"
to avoid cpp attempting to interpret it as a pre-processor directive.

.S means assembly. (that's why I went with .dts-cpp rather than .dts.cpp).
