This is the first set of omap cleanup patches for v3.8 merge 

window to remove most of the remaining plat includes to get us
 closer to ARM common zImage support.
 
 To avoid a huge amount of trivial merge conflicts with includes,
 this branch is based on several small topic branches coordinated
 with the driver subsystem maintainers. These branches are based on
 v3.7-rc1 and can also be merged into the related driver subsystem
 branches as needed:
 
 omap-for-v3.8/cleanup-headers-prepare   few trivial driver changes
 omap-for-v3.8/cleanup-headers-dma       move of the DMA header
 omap-for-v3.8/cleanup-headers-gpmc      GPMC and MTD changes
 omap-for-v3.8/cleanup-headers-mmc       MMC related changes
 omap-for-v3.8/cleanup-headers-dss       DSS related changes
 omap-for-v3.8/cleanup-headers-asoc      ASoC related changes
 
 Note that for the dma-omap.h, it was decided that it should be
 is completed. For the related discussion, please see:
 
 https://patchwork.kernel.org/patch/1519591/#
 
 After these patches we still have a few plat headers remaining
 that will be handled in later pull requests.
