I'm pretty sure we already have other platforms with an ATU. Those all just represent it with the other ctrl registers? So maybe this is TI specific that it is separate. Or should have some conditional like 'if the ATU space is separate, the reg-name should be atu'. > (The old way of getting the configuration address space from "ranges" > is deprecated and should be avoided.) > - num-lanes: number of lanes to use > -- > 2.17.1 > _______________________________________________ linux-arm-kernel mailing list linux-arm-kernel@lists.infradead.org http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
