Thanks for all you tiresome work dealing with the feedback from the
community and me and thank you for the cooperation so far.

You have managed to convert this display driver from something based on
a wrong abstraction to a driver that not only are using the latest DRM
infrastructure but also now have the correct structure and correct
bindings.

There are still things we can improve - but rather than doing it
alone we are better served with the driver applied to drm-misc-next
so we are more that can help and maybe even contribute.

Patches applied to drm-misc-next.
