This patch series adds more register documentation for shdma, and replaces
some hardcoded numbers by defines.
[1/4] dmaengine: shdma: Add more register documentation
[2/4] ARM: shmobile: dma: Use defines instead of hardcoded numbers
[3/4] sh: dma: Use defines instead of hardcoded numbers
[4/4] dmaengine: shdma: Use defines instead of hardcoded numbers

Hi Geert,
in order to try and create a smoother path for changes in this area to land
I have pushed them to the shdma-for-v3.17 branch of my renesas tree
on kernel.org. It is merged into the devel and next branches of that tree
and should appear in linux-next in the near future.
My intention is to send a pull-request for this branch once it has sat
in next for a short time. I hope that this approach is useful to all parties.

I am dropping this patch from the shdma-for-v3.17 branch (which I am
preparing for Vinod) as it depends on a patch in another branch of my tree
(which I am preparing for arm-SoC).
Could you please repost this patch once the other patches
in this tree have been accepted by Vinod.
Thanks
