drm: introduce a capability flag for syncobj timeline support
Unfortunately userspace users of this API cannot be publicly disclosed yet. This commit effectively disables timeline syncobj ioctls for all drivers. Each driver wishing to support this feature will need to expose DRIVER_SYNCOBJ_TIMELINE. v2: Add uAPI capability check (Christian) Signed-off-by: Lionel Landwerlin <lionel.g.landwerlin@intel.com> Reviewed-by: Christian König <christian.koenig@amd.com> (v1) Cc: Dave Airlie <airlied@redhat.com> Cc: Daniel Vetter <daniel.vetter@ffwll.ch> Cc: Christian König <christian.koenig@amd.com> Cc: Chunming Zhou <david1.zhou@amd.com> Reviewed-by: Dave Airlie <airlied@redhat.com> Reviewed-by: Chunming Zhou <david1.zhou@amd.com> Signed-off-by: Dave Airlie <airlied@redhat.com> Link: https://patchwork.freedesktop.org/patch/msgid/20190416125750.31370-1-lionel.g.landwerlin@intel.com
