Hi,

This series is a prerequisite for the power domain driver of NVIDIA Tegra
SoCs [1]. It extends the GENPD core with a better support of performance
states and eases linking of child/parent PDs for the PD drivers.

Changelog:

v5: - Renamed genpd_xlate_performance_state() and its arguments like it
was requested by Ulf Hansson and Viresh Kumar in a v4 review.

- Added r-b from Ulf Hansson to "Make set_performance_state() callback
optional" patch.

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
