Hi,

nice to see this work going on. For subsequent revisions, can you please
also Cc the Tegra mailing list (linux-tegra at vger.kernel.org) as well as
the Tegra platform maintainers (that's Jon Hunter and myself). This will
make sure that more people with an interest in this will see your work.
Not everyone follows dri-devel, linaro-mm-sig or linux-media.

Thanks,
Thierry
