No, you don't need to send another patch. I already merged just this one
(the DT documentation) with my own small fixes, with a plan to go into
4.5. You only need to send another version of patch 2 (the driver).

During the merge window, I'm stashing changes in l2-mtd.git's 'next'
branch, so we can keep stuff that's going to 4.5 separate from stuff
thats getting merged to 4.4 right now. You can see it here for now:

http://git.infradead.org/l2-mtd.git/shortlog/refs/heads/next

After the merge window closes (probably on Sunday), I'll bring this into
+master.

Brian
