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.
