OMAP3+ supports both device tree and non-device tree boot. Device tree bindings for OMAP3+ is supposed to be added via dts following: Documentation/devicetree/bindings/power/opp.txt
Since we now have device tree entries for OMAP3+ cpu OPPs, The current code wrongly adds duplicate OPPs. So, dont register OPPs when booting using device tree.
