Afaik, we haven't do much (or any?) maintenance on tilcdc_slave_compat.c since it was written, so from our perspective it's been a minimal burden. Is it creating burden for others? Is the approach done with tilcdc_slave_compat.c something that's not recommended? I'm sure similar situations happen with other drivers too, and I think it's a good idea to have a recommended way of keeping compatibility.
