+   int opal_sensor_group_enable(u32 group_hndl, int token, bool enable);
+
+OPAL call to enable/disable the sensor group using a handle to identify
+the type of sensor group provided in the device tree.
+
+For example this call is used to disable/enable copying of sensor
+group by OCC to main memory.
+
+The call can be asynchronus, where the token parameter is used to wait
+for the completion.
