Great news :)

I just tested your tree with my custom Overo-based board (OMAP3630). I
see some new warnings popping up, nothing dramatic at first glance. I
will continue testing to see if I lost something in the transition.

IMHO one remaining issue is the missing binding for the camera interface
(ISP). I saw recently an RFC from Sebastian Reichel to add the necessary
binding [1], but this work will probably take some time. So probably a
quirk is necessary here to bring up this IP.

Best regards,

Florian
