@Poofjunior Thanks for submitting!

Any chance you can split the PR to have one per board?
Additionally, while we do not enforce it, it would be great if you could:

• Include brief description of the device (e.g: Reserve cuTTLefishFip board #1 and Reserve Hobgoblin device #3)
• Make sure that the repositories have a valid device.yml

As a side note, and this is more from the AIND side, I thought the valve-controller was not going to be deployed yet, since it was mainly designed as an "abstract" device implemented, for now, by the delphi-controller. Is this still true?

Finally, it would be nice to discuss how to keep track of these boards that share the hardware target. We have had some of these discussions in the past (e.g. Behavior board hw1.2 and 2.0, Input/Output expander, Cuttlefish and Hobgoblin) but it seems like this case keeps coming back over and over again. Maybe its time to change the way the WhoAmI works to allow people to spin off their own devices a bit more easily.
