Hi,

Running next-20130827 I get the following probe failure on mx6:

[drm] Supports vblank timestamp caching Rev 1 (10.10.2010).
[drm] No driver support for vblank timestamp query.

I haven't started debugging it yet, but just wanted to know if someone
has already seen this problem or have any suggestions.
