The driver currently exposes several YUV formats but fails to properly program all the registers needed to display such formats. Add the right programming sequences so that overlay windows can be used to accelerate color format conversions in multimedia playback use-cases. Signed-off-by: Thierry Reding <treding@nvidia.com>
