As of now, there is no plan to move the older Samsung platforms to
DT-based model. Moving to DT-based model requires people with the
board support upstreamed for older Samsung SoC's to sign up for the dt
conversion process without which testing will not be possible. So for
now, we will have to maintain the old drivers also.

Thanks,
Thomas.
