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.
