Okay, before I went too far I thought to download archives and found that Klimann has been working on this, but last post I see is April 2013. I picked through and got what I think are the last discussed of the 3 files omap-pcm3168.c pcm3168.c and pcm3168.h. I did not mean to cross paths with anybody. I will compare these to what I have worked up and see what I can contribute.
I am a bit confused about one thing though. When I began this (before I knew I might be stepping on somebody else's work) I downloaded 3.10 sources from kernel.org. I have previously and again grepped through the sources and I find no mention of pcm3168. Has this project just not made it that far? And do I have the latest versions (plucked from the text archives, or are they in a git somewhere that I don't know about?
