Well this is not the omap_hsmmc.c driver, this is the one for earlier hardware that's available on omap1 and 2420. All the later ones use the omap_hsmmc.c driver instead. So this one we cannot make DT only unless we make mach-omap1 DT only, which is doable, but may never happen because of the effort needed. Most of the effort would be quite trivial, except for the conversion to use the common clock framework.
