Setting this flag might fix that. How would you recommend proceeding with this patch ? I can drop the eee-broken-1000t property as I didn't notice any issue, or keep with the risk that it my be cargo-cult. This is beyond my area of expertise, so I can perform tests if I get clear instructions, but I don't think I can investigate alone at this point. -- Regards, Laurent Pinchart _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
