This gets iATU register area from reg property. In Synopsys DWC version 4.80 or later, since iATU register area is separated from core register area, this area is necessary to get from DT independently.

Keystone has the same 'atu' resource setup. Please move its code to the DW core and use that. Rob _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
