TI did make a sink for V4L, if that is what you mean.  It doesn't  
create a V4L2 device, it uses one.  From this discussion, it sounds  
like you already have one and are looking for something to create the  
V4L device.

We are set to publish it in a week or two.  Contact me if you want to  
get early access.  I would have like to have seen it published earlier  
so that no one would need to contact me!
