Merge branch 'pm-opp'

* pm-opp:
  PM / Domains: Propagate performance state updates
  PM / Domains: Factorize dev_pm_genpd_set_performance_state()
  PM / Domains: Save OPP table pointer in genpd
  OPP: Don't return 0 on error from of_get_required_opp_performance_state()
  OPP: Add dev_pm_opp_xlate_performance_state() helper
  OPP: Improve _find_table_of_opp_np()
  PM / Domains: Make genpd performance states orthogonal to the idlestates
  OPP: Fix missing debugfs supply directory for OPPs
  OPP: Use opp_table->regulators to verify no regulator case
  OPP: Remove of_dev_pm_opp_find_required_opp()
  OPP: Rename and relocate of_genpd_opp_to_performance_state()
  OPP: Configure all required OPPs
  OPP: Add dev_pm_opp_{set|put}_genpd_virt_dev() helper
  PM / Domains: Add genpd_opp_to_performance_state()
  OPP: Populate OPPs from "required-opps" property
  OPP: Populate required opp tables from "required-opps" property
  OPP: Separate out custom OPP handler specific code
  OPP: Identify and mark genpd OPP tables
  PM / Domains: Rename genpd virtual devices as virt_dev
