I'll take a bash at it, although as there seems to be no binding doc 
for the driver and I can't find any other board that has axp209 
regulators defined I may need a bit of help to get this right.

What additional patches are we talking about?  The following:
regulator: axp20x: Use parent device as regulator configuration device
i2c: mv64xxx: continue probe when clock-frequency is missing
or are there others I'd need to pick out of linux-next?

linux-next 20140926 doesn't build for me:

   LD      init/built-in.o
kernel/built-in.o: In function `cputime_adjust':
:(.text+0x25588): undefined reference to `__bad_cmpxchg'
:(.text+0x255f8): undefined reference to `__bad_cmpxchg'
/data/linux/source/linux-next-org/Makefile:956: recipe for target 'vmlinux' failed

I suppose as a result of https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/kernel/sched/cputime.c?id=eb1b4af0a64ac7bb0ee36f579c1c7cefcbc3ac2c

having reverted that one, the resulting kernel doesn't want to talk 
to my SD card.  Both your tree and 3.16 work fine though.

Anyway, v2 on it's way.
