Definitely not. The component stuff is there to sort out the subsystems which expect a "card" but in DT we supply a set of components. It's not there to sort out dependencies between different subsystems. I've no idea why your patch to add the deferred probing hasn't been acked by Mike yet, but that needs to happen before I take it. Or, split it up in two so I can take the clkdev part and Mike can take the CCF part. -- FTTC broadband for 0.8mile line: 5.8Mbps down 500kbps up. Estimation in database were 13.1 to 19Mbit for a good line, about 7.5+ for a bad. Estimate before purchase was "up to 13.2Mbit". _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
