Hi Dave,
It's already -rc8, so this pull request is very late. Sorry about that. Still,
it'd be great to see this go in, as we've had issues with omapdrm for years,
which we've not been able to fix properly (like warnings/crashes when unloading
modules, page-flips tearing, race issues with fbs). All those problems seem to
be gone after this rewrite of omapdrm for atomic modesetting, and the resulting
code is much cleaner and more maintainable.
This has been mostly tested on OMAP4 Pandaboard, with single and dual displays.
Tomi
