Things are making progress. The intention is to get the base patches
into staging; however, the holiday season made the progress a bit slow
recently.

We don't have a fixed schedule; things make progress according to what
our projects make possible. The more customers we get behind this
effort, the more time we can spent on it.

- CSI is running on MX6 here
- Deinterlacer is WIP on MX53
- VPU was posted today, based on the Vista Silicon patches; we can do
  encoding and decoding, but not in all possible formats
- scaler works here
- We have a m2m plugin for GStreamer (which needs polishing as well, but
  works)

That's quite an old tree... especially the port to 3.5 made a lot of
headache until all the oftree and clock issues were solved. However,
it's still good for reference.

it's in a state that we think we can show it to you folks.
