Operating stable without reduced chip life at 1Ghz needs several technologies working: The technologies involve - SmartReflex - DVFS As this cannot directly specified in the OPP table as dependecies in the devicetree yet, use the turbo flag again to mark this OPP as something special to have some kind of opt-in. So revert commit 5f1bf7ae8481 ("ARM: dts: omap36xx: Remove turbo mode for 1GHz variants") Practical reasoning: At least the GTA04A5 (DM3730) has become unstable with that OPP enabled. Furthermore nothing enforces the availability of said technologies, even in the kernel configuration, so allow users to rather opt-in.
