I have to say I don't know much about DMM, but my understanding is that DMM is a bigger entity, of which TILER is only a small part, and DMM manages all memory accesses.
Can there be other users for the DMM than DRM? I know there could be other users for the TILER, and I know you want to combine that with the DRM driver, but I'm wondering about the other parts of DMM than the TILER.
Somehow having a DMM driver inside omapdrm sounds strange.
The DMM does indeed contain a number of entities. However, the TILER portion is the only part that requires a driver. All other register modifications (LISA map settings, EMIF, etc) are done statically in the loader or u-boot and never changed again. As such, DMM has become synonymous with TILER.
