Hmm...I hadn't thought of that. I can respin the dts to be
cyrus_5020.dts, and provide a cyrus_5040.dts later. That version of
the product doesn't exist yet. Does that make sense?

Well that's just a stupid mistake I made when I remade the device tree
by copying the 5020. I'll fix this.

I wondered about the allcaps, too, but there are already systems
floating around, possibly with dtbs with that compatible in there. I'm
reluctant to change it.
