Maybe they don't know better.. Christoph approached me privately (through Matus, because he was in the PHY driver header, I guess). I tried to collect as much information as possible and then posted it to the LKML. I don't see anything wrong here. I already mentioned I don't have any hardware to test. So all I tried to do was to help Christoph get a device tree blob to easily test on its hardware. -michael > Kernel development is fundamentally a difficult, frustrating and > depressing activity. _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
