Sorry for the late reply! I will apply it after 4.19-rc1 released. Thanks! Best Regards, Wei

The clocks property should either be present for all the CPUs of a cluster or none. If these are present only for a subset of CPUs of a cluster then things will start falling apart as soon as the CPUs are brought online in a different order. For example, this will happen because the operating system looks for such properties in the CPU node it is trying to bring up, so that it can register a cooling device. Add missing clocks property.
