Can we override this in the -u-boot.dtsi file? -- Tom$ grep -RI "clock-frequency = <2600000>" . ./arch/arm/dts/logicpd-torpedo-som.dtsi: clock-frequency = <2600000>; ./arch/arm/dts/omap3-igep.dtsi: clock-frequency = <2600000>; ./arch/arm/dts/omap3-beagle.dts: clock-frequency = <2600000>; ./arch/arm/dts/omap3-evm-common.dtsi: clock-frequency = <2600000>; ./arch/arm/dts/logicpd-som-lv.dtsi: clock-frequency = <2600000>; ./arch/arm/dts/omap3-beagle-xm.dts: clock-frequency = <2600000>; All of these would benefit.
