The main "issue" with the series is its dependency on Laurent Pinchart's
Common Display Framework (or rather on the progress of its upstreaming).
I'm planning to discuss this in details in during the Linaro Connect in
Dublin, but generally, if it's not getting merged in the next window,
I'll spin the series to use the standard video modes bindings instead of
CDF. This will make me hurt on Versatile Express, but should work for
others.
