Hi Chris, Simon, Vinod (in alphabetical order :-) )

Formally patches in this series belong to your 3 trees: 1-3 and 7 
(documentation, sent later separately) to DMA, 4 and 6 to ARM/shmobile, 5 
to MMC. However, they can actually be safely applied in any order, as long 
as per-tree patches are kept together. Even if the DMA portion is applied 
last, the MMC driver will find DMA DT bindings in the DT, will request 
channels, but no DMA channels will be found, then the driver will fall 
back to PIO.

So, it's up to you to decide, whether to pull these patches separately via 
respective trees, or have some of them acked and push all of them via one 
tree.

Thanks
Guennadi
