I cross-referenced the processor part number with the description from a distributor, and the part number also lists 375MHz, so I think we should leave 456 disabled. adam > + > &sata { > status = "okay"; > }; > -- > 2.20.1 > > > _______________________________________________ > linux-arm-kernel mailing list > linux-arm-kernel@...ts.infradead.org > http://lists.infradead.org/mailman/listinfo/linux-arm-kernel
