This computes what exactly changed in the modeset configuration, i.e. whether a full modeset is required or only an update of the framebuffer base address or no change at all. In the future we might add more checks for e.g. when only the output mode changed, so that we could do a minimal modeset for outputs that support this. Like the lvds/eDP panels where we only need to update the panel fitter. Reviewed-by: Jesse Barnes <jbarnes@virtuousgeek.org> Signed-Off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
