Yes and no :-)

It's part of my work to support colorspace conversion hardware. Now for 4.2 I merged
a lot of patches that pave the way for the remaining code to go in. But that remaining
code still needs to be cleaned up. My code can be found here:

http://git.linuxtv.org/cgit.cgi/hverkuil/media_tree.git/log/?h=csc

Unfortunately it's on hold because the CEC framework has priority for me (and Cisco).

In addition, for drm Intel is working on color manager code as well (see the patch
series titled "Color Manager Implementation" at dri-devel). I would like to be able
to share the low-level matrix/vector calculation code with them. So I am waiting to
see how that turns out.

So quite some work has been done, but it's not ready for merging.
