Merge branch 'pm-opp' into pm

* pm-opp: (37 commits)
  PM / devfreq: Add required OPPs support to passive governor
  PM / devfreq: Cache OPP table reference in devfreq
  OPP: Add function to look up required OPP's for a given OPP
  opp: Replace ENOTSUPP with EOPNOTSUPP
  opp: Fix "foo * bar" should be "foo *bar"
  opp: Don't ignore clk_get() errors other than -ENOENT
  opp: Update bandwidth requirements based on scaling up/down
  opp: Allow lazy-linking of required-opps
  opp: Remove dev_pm_opp_set_bw()
  devfreq: tegra30: Migrate to dev_pm_opp_set_opp()
  drm: msm: Migrate to dev_pm_opp_set_opp()
  cpufreq: qcom: Migrate to dev_pm_opp_set_opp()
  opp: Implement dev_pm_opp_set_opp()
  opp: Update parameters of  _set_opp_custom()
  opp: Allow _generic_set_opp_clk_only() to work for non-freq devices
  opp: Allow _generic_set_opp_regulator() to work for non-freq devices
  opp: Allow _set_opp() to work for non-freq devices
  opp: Split _set_opp() out of dev_pm_opp_set_rate()
  opp: Keep track of currently programmed OPP
  opp: No need to check clk for errors
