Hi Rob,

Soon (in linux-next, but off by default) this will be a warning for
undocumented compatible string. Use a real device.

Two questions:
(1) I guess this is also true for "PATCH 2/4", where you already added
your Reviewed-by?
(2) I'd add the "jedec,spi-nor" because, that is the one I target. But
before doing so, I'd need to add the otp subnode to the spi-nor
schema, correct? Otherwise, the schema validation will fail. Eg.
