The DaVinci maintainers are queuing GPIO patches for their driver
for this merge window, so requesting them to apply this patch.

I wont be sending any more pull requests for v3.14. Even if I send, the
ARM-SoC maintainers will not take it anyway. So likely this wont get
into v3.14. For v3.15, Linus should be able to queue it as dependencies
would have made it into the kernel by then.

Thanks,
Sekhar

But as it is a fix I believe the ARM SoC maintainers will apply it
directly to the davinci branch.

Wolfram: I suggest you send this patch with my ACK directly
to arm@kernel.org and ask it to be applied to the davinci branch
in the ARM SoC tree.

Sorry I did not realize this is a fix.

This would work too, I guess. Wolfram, can you please keep me in CC too
in case questions/actions come up?

Sekhar, I assume this is an ack from you too?  If so, Wolfram, please
include that in the patch submitted to arm-soc.

Wolfram, if you have not sent it already, please add:

Acked-by: Sekhar Nori <nsekhar@ti.com>

The branch to which the patch will be applied is davinci/gpio on
git://git.kernel.org/pub/scm/linux/kernel/git/arm/arm-soc.git. Please
rebase on this branch so it applies cleanly.

Thanks,
Sekhar

This patch is not in 3.14 yet. Are there any chances to have it in 3.14, 
as it introduces merge conflicts with future patches?

Hi Wolfgang,

should we take 1/7 and 6/7 via the mips tree ?
