Subject: [PATCH 0/2] PM / OPP: updates to enable sharing OPPs info

From: Sudeep KarkadaNagesha <sudeep.karkadanagesha@....com>

These are couple of updates to existing PM/OPP library to support
sharing of OPPs between different device nodes.

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.

Sudeep KarkadaNagesha (2):
  PM / OPP: add support to specify phandle of another node for OPP
  PM / OPP: check for existing OPP list when initialising from device
    tree
