$ 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.
