There is here no commit msg, no explanation.As I wrote in the cover letter, this and previous commits make things work on Exynos3250 (ARTIK5 precisely). I can't explain why. I read everything I could about this HW and there were no details about automatic CS handling other than how to turn it on and off.
At least this information would be useful. If vendor kernel also does it, that's another argument to use, since there are no better ones...
