Here's the set of 3 patches against the Simon Horman's 'renesas.git' repo, 'renesas-next-20130722' tag. Here we add the HPB-DMAC platform code working on the R8A7778 and enable DMA for SDHI0 on BOCK-W. The patchset depends on the R-Car HPB-DMAC driver patch posted earlier. [1/2] ARM: shmobile: r8a7778: add HPB-DMAC support [2/2] ARM: shmobile: BOCK-W: enable DMA for SDHI0 The former patch #1 has been merged to the next patch moving the data from the now removed <mach/dma.h> to <mach/r8a7778.h>.
