+PSCI v1.0 onwards, supports OS-Initiated mode for powering off CPU domains
+from the firmware. Such PM domains for which the PSCI firmware driver acts
+as pseudo-controller, may also be specified in the DT along with the domain
+idle states.
+
+The domain definitions must follow the domain idle state specifications per
+[3].
+
+The domain idle states must be specified using the optional node -
+
+- domain-states
+
+The domain states themselves must be compatible with 'arm,idle-state' defined
+in [1]  and need to specify the arm,psci-suspend-param property for each idle
+state. More information on defining CPU PM domains is available in [4].
+
