Support for DMM and tiled buffers. The DMM/TILER block in omap4+ SoC provides support for remapping physically discontiguous buffers for various DMA initiators (DSS, IVAHD, etc) which do not otherwise support non-physically contiguous buffers, as well as providing support for tiled buffers.
See the descriptions in the following two patches for more details.
Andy Gross (1): drm/omap: DMM/TILER support for OMAP4+ platform
Rob Clark (1): drm/omap: add GEM support for tiled/dmm buffers
