I'll put my hand up as a user of it. I run every release kernel
on KS8695 platforms, though I don't tend to do much testing of
rc kernels on it.

I am happy enough to ack and test changes, if no one else wants to
do it. I don't expect to do any real active development on it though.
I do have some board files that would have been nice to push into
mainline, but I have been holding off (for quite a while), hoping
that someone might support DTs on this sub-arch.
