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.

The IPU has other units missing in this patch:

- CMOS Sensor Interface (csi)
- Video Deinterlacer (vdi)
- Sensor Multi FIFO Controler (smfc)
- Image Converter (ic)
- Image Rotator (irt)

So expect more files to come in this directory.

Do you have a schedule for that? Are you waiting for more customer
projects at Pengutronix to do that?

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 would be great to finally have full IPU/VPU/GPU support for i.MX5
into upstream. As you already know, Linaro also have some video
support for i.MX5 in this head:
http://git.linaro.org/gitweb?p=landing-teams/working/freescale/kernel.git;a=shortlog;h=refs/heads/lt-3.2-imx5

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.

Is there a plan to merge all these developments into upstream?

From our side: definitely! Everything is posted here on the lists when

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