It is a daughter board.

Weighing up to include a DTS and overriding nodes versus splitting
out the commons into a DTSI let to the latter:
Overriding DTB nodes is a mess since it makes it unnessesarily complex
to understand what happens and is hard to debug. I spend quite some
time of my life to get a clou, why a DTB of a board is messed up and
why changes got lost. Including DTS files is a matter of taste and none
of my flavors.
Overlay would be an option, if there is a way to load the overlay
without touching the bootloader or during kexec.
