This improves the tw686x driver, adding support for features that were formerly
only available in the staging tw686x driver.
Krzysztof, please let us know if there are features that you need that are not
available in this driver. Otherwise I plan to remove the staging driver for
kernel 4.9.
Ezequiel, as a future follow-up patch it might be nice to automatically choose
between contig/memcpy and sg based on the requested field format.
Right now this is determined by dma_mode, but that can be improved.
It would also simplify the dma_mode since that would then be a bool saying
whether or not it should memcpy for stability.
I'm not postponing merging this series for that since this is already a
substantial improvement.
Regards,
Hans
