The driver currently has some limitations, in that it does not support the earlier s3c24xx socs, that cannot use every channel, but have special channel requirements for specific slave-targets. Another limitation is, that it currently does not support scatter-gather lists with more than element, due to me not understanding sg at first. While it does not hinder the usability, as all applicable Samsung drivers currently use only 1-element-lists, I plan to fix this in the next revision. In any case, I would be thankful for pointers to the obvious mistakes I'll probably have made, due to this being my first travel into dmaengine-land.
