Actually it is documented here:
Documentation/devicetree/bindings/arm/omap/omap.txt

In order to move all OMAP drivers to DT - as Benoit already mentioned -
we need additional work in DT.
At this point of time if we add the DT representation we anyways need to
change it as the core will receive the features, and we still need to
fall back to hwmod to get the drivers working.
As soon as we can migrate away from the hwmod we will do, but having
this in place helps us to migrate other parts to DT.
