Currently all the cpu nodes are parsed until the OPPs are found. This is essential to support cpuhotplug without having to replicate OPP information in all the cpu nodes. However in systems with multiple cpu power domain, its better to have OPP entry for each cpu. To avoid replication, phandle can be specified to the node which contains the full OPP information.
