I was aware of that and was going to handle S5PC210 (S5PV310) wariant in another separate patch. Your proposal looks OK but I am still working on how to use the extended capabilities of S5PC210 and for now I decided to just mask out the additional registers at offset 0x200 and above. This is for backward compatibility and also I do not see much advantage from using all 32 registers just an overhead of setting them up. So for now let us leave the CIO*SA(n) definition as is and after I work out a relevant output DMA usage scheme I will change it, possibly in the way you suggested.
