It seems I need to scrap this plan actually. Rob hit me with the clue bat on irc, and omapdrm does in fact install the "rotation" prop on the crtc. So I guess I need to rename the "rotation" prop to something else "crtc-rotation" maybe? Anyone have a good name up their sleeve?

To recap, you mean that the CRTC rotation property is to be the control over the rotation of the primary plane, and that we need a new property name for "rotate the world"? In which case, I'd suggest "rotate-all" since it seems akin to the action that you take upon setting it (as opposed to the state of the planes). -Chris
