Yeah, and let's not forget MSM8998/SDM835, because it wouldn't be fair that only the other SoCs get all the love! ^_^ Regards.

I had a quick look at the CAF branch seems like with minor changes we can have it working since the delta from 8996 appears minimal. I'll give it a try once I get my hands on a 8998 MTP. > Regards.
