The Timberdale FPGA video driver has not seen any real development
since 2011 (and very little before that).

One of the problems with the timblogiw driver is that it uses videobuf
instead of the newer vb2 framework. The long term goal is to either
convert or remove any driver still using videobuf. Since none of the
core v4l developers has the hardware, we cannot convert it ourselves.

As far as I can tell it was only used in an Intel demo board in 2009
using Meego:

http://www.chinait.com/intelcontent/intelprc/admin/PDFFile/20106411545.pdf

which has since been superseded.

Moving this driver to staging is the first step towards removal. After 2 or
3 kernel cycles it will be removed altogether unless someone steps up to
clean up this driver.

- checks for ->mode_fixup in non-atomic helpers from Carlos Palminha, plus
  removing dummy funcs from drivers. Carlos promised to follow up with
  more, since there's lots more silly dummy functions around.
- dma-buf patches from Tiago, except the ioctl itself (that needed a
  respin to address review from David Herrmann)
- encoder mask for atomic from Maarten

wouldn't wait.  If you moved the cursor fast enough, we could
potentially wrap around the display list memory area and overwrite the
existing display list while it was still being scanned out, resulting
in the HVS scanning out garbage or just halting.

Instead of making cursor updates wait for scanout to move to the new
