drm: add atomic properties
Once a driver is using atomic helpers for modeset, the next step is to switch over to atomic properties. To do this, make sure that any modeset objects have their ->atomic_{get,set}_property() vfuncs suitably populated if they have custom properties (you did already remember to plug in atomic-helper func for the legacy ->set_property() vfuncs, right?), and then set DRIVER_ATOMIC bit in driver_features flag. A new cap is introduced, DRM_CLIENT_CAP_ATOMIC, for the purposes of shielding legacy userspace from atomic properties. Mostly for the benefit of legacy DDX drivers that do silly things like getting/setting each property at startup (since some of the new atomic properties will be able to trigger modeset). Signed-off-by: Rob Clark <robdclark@gmail.com> [danvet: Squash in fixup patch to check for DRM_MODE_PROP_ATOMIC instaed of the CAP define when filtering properties. Reported by Tvrtko Uruslin, acked by Rob.] Signed-off-by: Daniel Vetter <daniel.vetter@ffwll.ch>
