Ping? This panel is needed for a system I am working to get upstreamed.
I can confirm that the timings are in use several months and well tested.

FYI The dts for the board using this panel is now in linux-next.
Is there something more I need to do to get it queued?
They are my first patches for the drm subsystem, so I may be 
unfamiliar with the customs.

I just checked; the patches still apply cleanly against linux-next.
