Hi,

This is a continuation of [1], where Ulf Hansson suggested to factor out
GENPD patches into a separate series. This series is a prerequisite for
the power domain driver of NVIDIA Tegra SoCs.

[1] https://patchwork.ozlabs.org/project/linux-tegra/list/?series=221130

Changelog:

v4: - Updated the "Make set_performance_state() callback optional" patch.
      Now the case where one of intermediate domains doesn't implement
      the set_performance_state() callback is handled properly, thanks
      to Viresh and Ulf for catching this drawback and suggesting the fix.

    - Added more r-bs from Ulf Hansson and Viresh Kumar.

v3: - Added r-b from Ulf Hansson.

    - Added new patch "Make of_genpd_add_subdomain() to return -EPROBE_DEFER",
      which was suggested by Ulf Hansson.

    - Improved "Add "performance" column to debug summary" patch by
      correcting the formatting of debug output, which had a superfluous
      whitespace.

Dmitry Osipenko (3):
  PM: domains: Make set_performance_state() callback optional
  PM: domains: Make of_genpd_add_subdomain() to return -EPROBE_DEFER
  PM: domains: Add "performance" column to debug summary
