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.
    [    0.837632] imx-drm display-subsystem: bound imx-ipuv3-crtc.0 (ops ipu_crtc_ops)
    [    0.845214] imx-drm display-subsystem: bound imx-ipuv3-crtc.1 (ops ipu_crtc_ops)
    [    0.852720] imx-drm display-subsystem: failed to bind display@di0 (ops imx_pd_ops): -19
    [    0.860994] imx-drm display-subsystem: master bind failed: -19

Will try to debug this later.

Regards,
Wladimir
