A very common case is for MFDs where you've got a core driver which is
either being newly added or as far as external interfaces go having some
defines added to it and then a bunch of basically unrelated driver
patches.  There is often a build time dependency (not so much with the
newly added stuff) so there is an actual dependency but no meaningful
overlap with reviews.  You get a similar thing with people bringing up
new SoCs where they send a minimal set of drivers in the initial series
so people can usefully test.
