Now that the omapdss interface has been reworked so that omapdrm can use dispc directly, we have been able to fix the remaining functional kms issues with omapdrm. And in the mean time the PM sequencing and many other of that open issues have been solved. So I think it makes sense to finally move omapdrm out of staging.
