I'm not quite sure what you're saying. There are no ifdefs in the driver
related to CONFIG_DMA_OF, so there's no code (ifdefs) that could benefit
from (be removed due to) assuming that.

Do you mean this driver should be updated to support the generic DMA DT
bindings? Yes, that's true. However, a patch to do so would be
completely unrelated. We've been holding off doing such a conversion
until the dmaengine core support for CONFIG_DMA_OF is in the kernel, so
we can use it.
