You most likely want to preserve it, while keeping a sensible polling frequency, so that userspace will be aware of the current CPU temperature. <100> sounds like a sensible value here. Konrad

Hence no need to configure polling frequency. I will remove polling-delay-passive/polling-delay. Thanks & Regards, Manikanta.
