I'm trying to, but getting a non-clock-related problem on the i.mx51 babbage board
with current kernel preventing the display from coming up at all:

    [    0.824712] [drm] Supports vblank timestamp caching Rev 2 (21.10.2013).
    [    0.831411] [drm] No driver support for vblank timestamp query.

I believe this should be fixed by

Thanks,
With that patch and Lucas' patch series applied, I can confirm to have working a console on DVI!
