Interconnect provider can't be optional if interconnect properties present in a device-tree because drivers that use ICC path will get -EPROBE_DEFER until ICC provider is registered. Older device-trees don't have ICC properties, and thus, the ICC users/consumers will get a dummy NULL ICC path in this case. I.e. ICC core handles this for us. _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/dri-devel
