Is the driver stack completely opensource?
If you don't include the trusted application(firmware) then yes.
I can't post it in a short time, because the firmware is not released 
yet. While the v4l2 still lacks many features I need here. If I release 
it in a short time, you would just get a version that outputs non-tile 
linear pixel formats here, the tile formats were only used for internal 
buffers.

Besides this TEE in our platform is not optee, even I posted it I don't 
think it could be merged in a short time.
