Or maybe it's identical to the CM3? It's supposed to be a drop in replacement
after all - and the other differences (wifi chip, usb hub) of the 3+ should not
apply to a CM.
So I guess either you send a patch to Linux that adds the cm3plus and only
changes the compatible/model properties over cm3 or we make the dtb name in
this patch the cm3 one.
