  OPP: Prevent creating multiple OPP tables for devices sharing OPP nodes
  OPP: Use a single mechanism to free the OPP table
  OPP: Don't remove dynamic OPPs from _dev_pm_opp_remove_table()
  cpufreq: mvebu: Remove OPPs using dev_pm_opp_remove()
  OPP: Create separate kref for static OPPs list
  OPP: Don't take OPP table's kref for static OPPs
  OPP: Parse OPP table's DT properties from _of_init_opp_table()
