This is a reduced version of the patchset which adds power management
support to NVIDIA Tegra drivers. Viresh Kumar asked to send these PD/OPP
patches separately for now to reduce the noise and finalize the review.

I implemented new get_performance_state() GENPD callback as was discussed
in v8. GR3D driver patch shows how it's used by consumer drivers, which
is a good example because 3d driver supports both cases of a single and
multi-domain hardware, it also uses OPP API more extensively than other
drivers.

Dmitry Osipenko (8):
  opp: Add dev_pm_opp_from_clk_rate()
  opp: Allow dev_pm_opp_set_clkname() to replace released clock
  opp: Change type of dev_pm_opp_attach_genpd(names) argument
  PM: domains: Add get_performance_state() callback
  soc/tegra: pmc: Implement get_performance_state() callback
  soc/tegra: Add devm_tegra_core_dev_init_opp_table_simple()
  gpu: host1x: Add host1x_channel_stop()
  drm/tegra: gr3d: Support generic power domain and runtime PM
