In general it's not a good idea for individual drivers to add top-level
meson.build options. If every driver does this for all its options we will
have an unmanageable set of hundreds of options. Unfortunately, though, I
don't see a really good way to replace this with something other than a
build option - I assume it's not just good enough to check which of the
dependencies is found/not-found? Is there some way that this can be a
generic option, that may be applicable to other drivers? Could the option
be instead to prioritize FIPs compatibility?
