Only nit is that the timings_set flag isn't very descriptive, but that's not the fault of this patch. Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org>

Yeah, that's just an artifact from the old crtc helper code, with the new compute_config callbacks we could precompute sane crtc timings. I'll fix this up for 3.12 > Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Picked up for -fixes, thanks for the review. -Daniel

We might want to switch around the core code to just fill in defaults, but this code predates the pipe_config modeset rework. And in the old crtc helpers we did not have a suitable spot to do this.
