Modified: trunk/target/linux/lantiq/dts/TDW89X0.dtsi Log: lantiq: TDW89x0 - increase spi frequency Use the same max spi frequency as set in u-boot. According to the datasheets, the Q64-104HIP as well as the Winbond 25Q64FVSIG support spi frequencies up to 50 MHz. During my tests, the Q64-104HIP couldn't be recognized/initialized if the frequency was > 40MHz. Both chips do support fast read as well. While touching the dts file, I fixed the dtc compiler warnings.
