Ok, I wanted to just test -next, but the latest is still of 22 Aug and 
that's too old. So, I took the current sh-mobile tree and merged your 
tree on top. There was 1 merge conflict in arch/arm/Makefile, but that's 
unrelated. After doing that I've discovered the following problems:

1. you applied a wrong version (v1) of my patch "DMA: shdma: support the 
new CHCLR register layout" - not v2, whose patchwork ID I provided:

> DMA: shdma: support the new CHCLR register layout
> pw ID: 2825593

I suggest to revert that commit and apply the correct one.

2. you missed this patch:

> DMA: shdma: move two macros to a header
> pw ID: 2831934

Please, pick it up too, even though it's just a cosmetic one.

3. Your merge:

commit ba1e06e3dff9a0bb0758d169e50cbb04a67a402c
Merge: daabb76 74cd26c
Author: Vinod Koul <vinod.koul@...el.com>
Date:   Sun Aug 25 13:22:06 2013 +0530

    Merge branch 'topic/sh' into next

    Conflicts:
        drivers/dma/sh/shdmac.c

dropped a "const" from a variable, which now generates a compiler warning. 
I'll send an incremental fix for that soon.

After fixing all the above the tree seems to be in a proper state. After 
your tree is fixed we can push ARM patches too.

Thanks
Guennadi
