OK, no problem. Andrew said he's happy to hold off the driver merge
for a bit and we should be able to drop it in post-rc1 if we can get
it sorted out.

I don't want to make a big stink out of it. But I don't understand
why half (or 1/5th) of a driver is a particularly good unit of change.
1. basic functionality, 2. more stuff, 3. documentation, 4. kconfig or
some such splitup seems more appropriate if it really must be split,
but IMO each change should as much as possible result in a coherent
complete source tree before and after.

Anyway, yeah, no big deal so if Andrew decided to merge them together
or leave them split, I go along with that ;)
