Well, the whole point of the new compatible string format is that it
can be generated by boot firmware at runtime, so I don't have a static
DTS with this that I can check into the kernel tree. The first user of
these bindings will be the
arch/arm64/boot/dts/qcom/sc7280-herobrine-villager-r0.dts board that's
already in the tree, but since these nodes get generated you won't see
them in that file. It's kinda like /chosen/kaslr-seed, that's also a
valid binding with a schema description that's actively being used but
doesn't show up in any DTS file checked into the tree.
