Color keying can be > source color keying or destination color keying. > > OMAP3 has three pipelines one graphics plane and two video planes.

Also we should have the CID to > enable/disable the color keying functionality. > > Please let us know your opinions/comments. > > [Shah, Hardik] Hi Any comments on above IOCTLs, Hans/Mauro, Shall I send patch to add these new ioctls.
