i.MX6DL - How many framebuffer can I use?

[호영노]

I used I.MX6DL. It has 1 IPU.

I used fb0 to camera output. and fb1 to QT's application area.

These are out put to LVDS. 

And I can mirroring the fb0 or fb1 to fb2. fb2 is output to External monitor. 

But I need 2 of framebuffer (fb0 and fb1 ) output to external monitor.

Is there any method to adding the 1 more framebuffer(fb3) in i.MX6DL ? 

Thanks.
