Tiling and Isometric Lightweight Engine for Rotation (TILER) driver

Dynamic Memory Manager (DMM) is a hardware block made by Texas Instruments. Within the DMM exists at least one TILER hardware component. Its purpose is to organize video/image memory in a 2-dimensional fashion to limit memory bandwidth and facilitate 0 effort rotation and mirroring. The TILER driver facilitates allocating, freeing, as well as mapping 2D blocks (areas) in the TILER container(s). It also facilitates rotating and mirroring the allocated blocks or its rectangular subsections.

How does this relate to DRM/GEM? I don't understand too much about graphics drivers, but it does sound like there is some overlap in functionality.

I guess at the very least the DMM should live in drivers/gpu/ instead of drivers/misc, but perhaps it could be integrated more closely with the existing code there.
