Which odd warning?
I don’t get any warnings when running (or at least warnings related to rig, because I get warnings related to other yamls):
make dt_binding_check DT_SCHEMA_FILES=Documentation/devicetree/bindings/rng/brcm,bcm2835.yaml

Why not?
Wouldn’t just be required for brcm,bcm6368-rng?
Anyway, I can omit this, since it would be the same for clocks and those aren’t required either.
