Be worth noting a little more explicitly in the commit message
you updated this logic as part of the move. I would even be
tempted to put it as a separate patch personally.

It is probably better to leave these two structures exported from
the primary module. These devices could technically have SPI
support added in the future and it might as well reuse these same
data structures.
