[PATCH v4 0/3] GENPD API improvements

[Dmitry Osipenko <digetx@gmail.com>]

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.

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.

  PM: domains: Make set_performance_state() callback optional
