the IPU code could still use a bit of testing, and I hope adding
features like VGA output on common development boards will increase the
amount of scrutiny this code will get.
I expect the structure of the IPU drivers to change when the common
display framework gets introduced at last, also requiring changes to the
device tree bindings, and I'm a bit reluctant to push for mainline
proper while the bindings are still not clear.

Philipp
